Thin-walled stainless pipe: sale delivery pipe stainless price excellent- stainless steel pipes available. Advantages of corrugated stainless pipes for water supply, installation and maintenance rules

Modern plumbing equipment makes the installation process of communication systems less time consuming. More recently, manufacturers of such products presented another novelty - stainless corrugated pipe. Based on this material, it is possible to create gas supply, water supply and heating systems. Durable and flexible material is very popular among craftsmen.

  Corrugated Pipe Features

For the first time, a corrugated stainless pipe for water supply was used by Japanese experts. Gradually, products conquered the European market.

Among the characteristic features of corrugated stainless steel water pipes are:

• The ability to withstand high pressure   with a slight wall thickness (from 0.25 to 0.3 millimeters). This property allows the installation of tubular products in systems operating autonomously and centrally.
• The use of high quality steel with a special chemical composition as a raw material. The concentration of the constituent components is controlled with particular accuracy.
• The ability to bend the product with a minimum radius. Depending on the design features, this indicator can have a value of 30 to 150 millimeters. This greatly simplifies the installation of the system.
• Simple processing. The ability to cut corrugations with conventional scissors or grinders is very important. However, experts recommend using a special pipe cutter (read: "").
• Long tube products. The corrugated metal pipe for water supply is supplied with bays in which lengths of material of length are laid. This allows you to install the system with a minimum number of connections, which increases the hermetic properties of the system.
• High temperature resistant. Corrugated stainless steel pipe can withstand a fairly high temperature. The linear expansion coefficient of this material is much lower than that of plastic counterparts.

  The technology of manufacturing pipes for water supply

The manufacturing process for corrugated stainless steel tubular products is fully automated. The absence of a human factor provides high precision   performing basic technological operations.

The most reliable are Japanese-made products. But the ratio of price and quality meets the goods of companies from Latvia.

The production of stainless pipes for water supply consists of several main stages:

• In the first step, the steel strip is pretreated. After that, the workpiece is fed to the molding line, where the tape is bent until a cylindrical workpiece is obtained.
• Then the joint is welded. This process takes place automatically in a special environment of inert gases.
• Next, rolling smooth workpiece using parts of different diameters. The result of this process is corrugation for stainless steel water pipes.
• The final stage is the cutting of products into parts of a certain length. Most often, it is cut into pieces of not more than 50 m, which are wound into a bay. This makes transportation of material more convenient and also facilitates installation work.

The depressions and protrusions may have different parameters, since each manufacturer produces products in accordance with their Technical Specifications and Standards. It is worth noting that this does not affect the quality of tubular products.

  Advantages and disadvantages of corrugated pipe

Comparing corrugated pipes for water supply with similar products from other materials, one can note the great superiority of corrugated pipes.

This is due to the main advantages of the material:

• Durability. Water pipes made of stainless corrugated tubular products can be operated forever. Only o-rings have a limited life.
• The combination of ductility and rigidity. The optimal ratio of these properties makes the material resistant to water hammer.
• Flexibility. Thanks to this quality, you can perform turns without using special tools.
• When freezing the working fluid, corrugated stainless pipes for water supply do not deform and do not burst.
• Corrugated pipe can be installed under the skin, plaster and even under concrete screed.

  Stainless corrugated pipe assembly

Corrugated stainless steel pipes are used to assemble water pipes. In some cases, it is possible to install material for gas supply and as an adapter in heating systems.

Fittings for connecting corrugated water pipes must exactly correspond to the list recommended by the manufacturer of corrugated pipe products. Purchasing cheaper connection elements can cause an emergency.

The installation of a corrugated steel pipe system is carried out similarly to pipe products from other materials. However, the flexibility of the corrugated pipe makes the installation process easier and faster.

Installation of the pipeline is carried out in a certain sequence:

• The distance between the connection points is measured, an addition to the bend is made and the desired piece of material is separated. For cutting, you can use a pipe cutter or other cutting tool.
• At the fitting, the union nut is loosened with a special key and the tubular is inserted into the inner part of the fastener until it stops.
• Using the same wrench, the nut on the fitting is tightened, completely fixing the product inside the fitting.
• Performing bends, the pipeline is given the necessary configuration. To fix the pipe on the wall, special fasteners are used.
• The system supplies a working fluid to check for leaks. If there are no leaks, you can start operating the pipeline.

For any technical product, there are certain rules for installation and operation. Perform these steps with a corrugated pipe in accordance with the following requirements:

• Installation of corrugations for water pipes should only begin after a complete check. In this case, cracks, dents and kinks are not allowed.
• It is not recommended to use fittings that are made of corrosive material to join.
• On supply pipes made of ferrous metal, a water filter must be installed in front of the brass fitting.
• When installing corrugated material, its twisting should be avoided.
• Do not allow the stainless steel pipe to come into contact with ferrous metal, which may be corroded.
• It is best to fix the corrugation with stainless steel products. For reliable fixation, you can use plastic fasteners. Non-ferrous metal fasteners will give greater elasticity to the created communication.
• Using a stainless corrugated water pipe in the system of additional floor heating, additional connections should not be allowed. It is very important that the segment is solid.
• Do not use electric shocks on stainless steel products.
• Bend and unbend the product should be the minimum number of times. The best option for this parameter is indicated in the passport.

  Regulatory documents

Information regarding electric-welded steel products is specified in GOST 10705-80. The same document describes the requirements that corrugated products must meet for communication systems, including water and gas.

Product quality is determined by the results of the tests to which selected samples of manufactured products are subjected.

The quality of the seam is checked by additional testing with hydraulic pressure.

The chemical composition of steel is regulated by GOST 22536.0.

Annealed stainless steel corrugated pipe is produced in accordance with paragraphs GOST 9941-81. They contain information regarding heat-deformed seamless products.

The main regulatory document in this area is the ISO 10806 standard adopted by the International Organization for Standardization in 2003.

Pipes for hot and cold water: which are better?

Before buying pipes for a water supply system, it is necessary to determine the conditions of its operation, maximum temperature   and pressure in the pipes.

The main types of pipes for water supply systems:

• corrugated stainless steel pipes - the most modern and durable option;
• copper pipes;
• steel pipes;
• metal-plastic pipes;
• polyethylene pipes   for water supply;
• polypropylene pipes   for water supply.

Corrugated stainless steel pipes for water have a number of significant advantages over other types of pipes: corrosion resistance, long service life (limited only by the life of the sealing rings in the joints), the ability to withstand mechanical damage and temperature extremes. Water pipes made of stainless corrugated pipe are the best choice both in terms of quality and in terms of cost.

Copper pipes - have some limitations during operation, there should be no impurities in the liquid passing through them, and the transported liquid itself should not be alkaline or acidic. If the operating rules are not followed, the pipeline quickly deteriorates. In addition, copper water pipes are significantly more expensive than flexible stainless corrugated water pipes.

Steel pipes - obsolete material for the construction of water supply systems, is unacceptable for cold water supply for two reasons - corrosion (condensate forms both on the surface of the pipes and inside); mineral deposits and sand inside the pipes.

Plastic pipes - easy to use, easy to bend, but since the pipes are made of materials with different expansion coefficients, with constant changes in pressure in the pipeline, leaks in the pipes may occur.

Polyethylene pipes for water supply are not resistant to ultraviolet radiation, which reduces their service life.

Polypropylene pipes for water supply have difficulties with maintenance   and repair.

The main characteristics of corrugated pipes for water supply

Corrugated stainless steel pipes are resistant to aggressive environments, as well as to acid and alkaline. The service life of a corrugated pipe for water is estimated at decades, more than 30 years. The appearance of rust is excluded, both inside the pipeline and outside. Stainless steel tolerates negative temperatures, the corrugated pipe line withstands temperatures of transported liquids above 100 degrees, as well as high water pressure in the pipes.

An important feature of corrugated stainless steel pipes is a fairly easy installation that does not require special equipment.

Due to the fact that corrugated pipes for water supply from stainless steel are delivered in bays of 50 m each, the number of connecting fittings for them is reduced (in comparison with other types of pipes), which allows to increase the life of the pipeline and reduce its cost.

Since ancient times, mankind has always strived for comfortable housing. Whether it was the first skin on the cave floor or ultra-modern heating systems - it all comes down to a person’s desire to live comfortably. Now we get gas, electricity, and water through the pipes. Previously used alloys for pipe production were short-lived and subject to corrosion, so they were replaced by corrugated culverts, which have a huge advantage over outdated water supply systems.

General information

Corrosion-proof corrugated pipes were invented by the Japanese in the last century. Experts around the world have recognized that stainless steel pipes have more advantages than those made of metal-plastic or polypropylene. In the modern world, it is considered that South Korea is the largest producer of corrugated pipes. Korean companies export their product to dozens of countries.

On the market is an abundance of variety of stainless corrugated tubes. You can purchase both Korean-made and analogues.

Water supply, which is made of corrugated products, has several times more advantages than metal pipelines. Due to the low thermal deformation, the lines do not bend, and such are often used for sewer systems. Corrugated pipes are very easy to cut, you only need a hacksaw for metal or another type of tool.

Corrugated stainless plumbing products have one distinctive characteristic feature. From other pipes, they are distinguished by the presence of a huge number of stiffeners. Models with a smooth surface can be laid only at a certain distance. Stiffening ribs make it possible to bend work at any angle. These products are manufactured using new technologies for the smelting of metals. Therefore, the corrugated pipe is durable and hardy.

Main varieties

To date, two types of pipes are available: those designed for sewerage and analogues for carrying out work on pulling power and low-current cables (computer UTP and telephony). Cast iron pipes have not been used for water supply for a long time, as new improved options have appeared. Classification of stainless corrugated pipes by strength:

1. Lungs.
2. Heavy.
3. Extra heavy.

Whatever the type of product, there are two methods for their manufacture: with a probe and without a probe. The probe, in turn, is a coarse wire that is part of the corrugation and serve to conveniently lay the corrugated pipe.

But it is customary to classify corrugated stainless options based on their diameter. And the diameter can be 15. 20, 25 or 32 millimeters. There is, of course, the production of pipes with a different diameter. But this happens on order and in small batches.

Scope of use of stainless corrugated pipes

Corrugated stainless steel pipes can be used in various fields. This fact is due to affordability and good technical characteristics. Application:

• heating systems (underfloor heating is especially popular);
• plumbing hot and cold water;
• air conditioning devices;
• fire extinguishing systems;
• electrical wiring.

Due to its excellent strength (since the main material is stainless steel), stainless pipes can be mounted on all possible types of production (chemical, agricultural, medical). Such products are easy to transport, do not lose their unique qualities even when pressed. What can not be said about plastic pipes.

Corrugated pipes are very often used for piping water to a dwelling and connecting plumbing to risers. Flexibility allows you to install it in distant places where it is impossible to install smooth pipes. And aesthetics do not require the destruction of walls. Very easy to install, for which you need a few wrenches.

Advantages and disadvantages

Stainless corrugated pipe has many advantages that prevail over the negative sides. The main advantages of using:

1. Long service life: this is facilitated by the material from which they are made, because stainless steel is not susceptible to corrosion, rot. This is what means that these kinds of products last forever.
2. Resistant to water shocks.
3. Excellent elasticity: no special tools are required to bend the corrugated pipe. In this case, the passage channels remain unscathed, there are no cracks.
4. They can be in contact with any material: such a pipeline can be poured with concrete, sheathed with plasterboard or any other material.
5. Not afraid of mold, insects.
6. Minimum installation time: extremely easy to install, no need to solder and weld anything. But the main thing is that this speed does not imprint on quality.
7. Light weight, quiet operation.

Nothing is perfect, so stainless steel corrugated tubes have a number of disadvantages:

1. First of all - a high price (but, depending on what to compare, for example, a copper pipe will cost several times more than this type of pipe).
2. Monitoring and replacing fittings. Over time, the o-ring loses its primary properties, so it must be replaced in order to maintain the tightness of the system.
3. Corrosion-proof corrugated pipe can become dirty, the difficulty is that due to the many bends it is very difficult to clean.

Today, every home has a wide variety of communication systems. The most important is centralized and sewage water supply. For this, numerous varieties of pipes are used.

In past years, heavy massive pipes made of cast iron were used for heating. But progress does not stand still, the material has also changed, from which pipes for sewage and water supply began to be made.

Cast iron pipes completely replaced lightweight modern designs. Various types of alloys were used to make such pipes, but they quickly rusted and collapsed. They were replaced by corrugated culverts and sewers.

These parts are lightweight, made of several types of material, and have excellent properties.

Varieties of corrugated pipes

Corrugated parts, made of stainless steel, in most cases are used for mounting ventilation pipes. They protect electrical wiring, sewer and plumbing systems. The price of such pipes is quite high. They withstand surges in temperature and high pressure.

PVC corrugated pipes   apply much more often. They are characterized by increased strength, their price is quite affordable. In addition, such PVC products are not deformed and can be operated for many years in the sewage system.

To protect the wires, a corrugated pipe made of PVC is mainly used. The price of such products is low, and the part is highly practical.

A disadvantage of corrugated PVC pipes is their easy ignition.

Corrugated stainless pipes

Water supply and sewerage systems made of corrugated stainless pipes have a lot of positive qualities when compared with ordinary metal water pipes.

In the manufacture of such corrugated elements, high quality stainless steel having the appropriate chemical composition is used. Thanks to this, such material acquires several positive characteristics:

When the wall thickness of the corrugated pipe reaches 0.3 mm, it can be mounted in places of high fluid pressure. Therefore, it has found wide application in heating, sewage and water supply systems.

Installation of stainless sewer corrugated products is much easier due to the flexibility of the material. The price of such work is available to anyone.

Corrugated stainless materials resistant tolerate high temperatures. They have low thermal deformation, therefore, the line does not bend, unlike polypropylene communications. They are often used for laying sewer systems.

Such a product easy to process. It is easily cut with any hand tool. You can use a grinder or other tool.

The plant produces stainless corrugated pipe in long coils. This makes it possible to reduce the number of joints when laying the line. No brass fittings required.

Key Features of Corrugated Stainless Pipe

Some features of corrugated water pipes

Their important difference is the presence of a large number of stiffeners. All ordinary models have a smooth surface, they can be laid only at a specific distance.

In a corrugated part, the stiffeners resemble folds that allow it to bend in any direction at any angle.

This product is manufactured using a special technology for the remelting of material. It turns out a high-strength design with great endurance. The part can bend regardless of the angle of bend, which is very important when laying sewers.

One of the positive qualities of this corrugated water pipe, is the application of welding. The corrugation is bent in any direction, and the length of the bay is enough to equip the water supply in any working area.

To further strengthen the corrugation, carry out its reinforcement. To improve the strength properties of a corrugated pipe, it is made of several materials.

If you want the water supply system laid in your house or site to exist for many years without repair, you can advise using corrugated pipes. As a result, you get a reliable and very durable design.

We can safely say that carbon ends its service and is inferior to the more promising analogue of stainless steel. The first consumes an operating resource too quickly, lends itself to corrosion and various internal deposits, which reduces the diameter of the product and affects the quality of the transported water. It is more rational to buy a stainless steel pipe. This product is devoid of the mentioned disadvantages due to the presence in the composition of more than 13% chromium. This feature influenced the resistance to destructive effects, up to 50% nitric acid.

Scope and advantages

In Moscow, a stainless steel pipe is used in the implementation of various tasks:

• installation of water supply networks - for transporting hot and cold liquids;
• the device "warm floor";
• stretching gas communications;
• development of fire extinguishing systems where water is used.

As a basis for heating and water supply, such seamless products are considered ideal. The cost of a stainless steel pipe is relatively low, and the operational characteristics are several times higher than those of analogues from other materials. Products differ:

• mechanical strength;
• resistance to corrosion;
• durability (service life - about 400 years);
• ensuring optimal quality of contacting water.

The indifference to alkalis and acids made them indispensable in the chemical, food and pharmaceutical industries. Needless to say, buying a stainless steel pipe for a heating boiler or water supply network is the best solution.

The product range includes different diameters: 12x0.8, 15x1.0, 28x12 and 35x1.5. Depending on the dimensions, the price per meter of a stainless steel pipe also differs.
