Corrugated stainless steel pipes: production and application features

Despite the fact that stainless steel pipes as a separate type have been used for a long time, corrugated stainless steel pipes appeared on our market only a few years ago. And immediately took a worthy place among buyers – because their performance properties are among the most attractive.

Advantages of corrugated stainless steel pipes

Corrugated stainless steel pipes can be annealed or not annealed. This classification is conditional, but it is this characteristic that determines the strength and reliability of the pipe. Meanwhile, all corrugated stainless pipes have a lot of advantages, the most significant of which we will consider later.

The maximum exploitation of the

According to manufacturers, the service life of corrugated stainless steel pipes is several hundred years. It is not yet possible to test this experimentally, since very little time has passed since the release of the first such pipe. However, it is known that the technical parameters of the pipe do not change during operation. And even if microcracks appear on the surface, this does not affect the overall condition.

Flexibility

This indicator is due to the fact that the pipe surface is corrugated. Thanks to this, it can be subjected to a variety of loads – from temperature changes to flexion and extension at almost any angle. In addition, such pipes practically do not change their structure even with strong impacts.

Reliability

This indicator is based on the fact that corrugated stainless steel pipes do not need to be constantly serviced. As a result, they can be installed even inside drywall walls. Such a pipe is installed once and for centuries, so we can definitely say that you will not have to disassemble the wall suddenly. In this regard, corrugated pipes are now increasingly used for laying cold and hot water supply systems.

Prevention of internal deposits

If you pay attention to the parameters of the inner surface, you will find information that it does not Deposit scale or other destructive elements. In this regard, such pipes are almost an ideal option for laying hot water systems. And even after a few years, the structure of this pipe will remain unchanged.

Easy to transport and store

Corrugated stainless types take up very little space when assembled. Thanks to this, they can be folded compactly on almost any site. In addition, such pipes can be transported over any distance without involving additional special equipment.

 Well, another advantage of corrugated stainless pipes is their high degree of environmental safety. When using such pipes, no harmful substances are released into the air. In addition, these pipes are not exposed to harmful bacteria, rodents and other harmful organisms, and also have a fairly presentable design.

Manufacturing technology and scope of application

Only steel with a high concentration of chromium and Nickel is used in the production of corrugated stainless pipes. This factor explains the fact that such pipes are reliably protected from harmful effects and corrosion.

Special attention should be paid to the production technology of corrugated pipes. In particular, it consists of several consecutive stages:

• Creating a pipe from a steel strip based on stainless steel;
• Using automatic welding, the tape is bent and its edges are connected to each other;
• A laser is used to check the quality of the weld and if any defects are detected they are promptly eliminated;
• With the help of a complex consisting of several shafts, a smooth steel pipe turns into a corrugated one;
• Thermal effect on the pipe to make it flexible. Applies only to annealed pipes;
• Creating multiple pipes from a single pipe by cutting them into individual products of the desired length;
• The folding of the individual pipes in the Bay.

 After completion of all technological procedures, the finished product must be pre-checked for the presence of microcracks and other defects. To do this, the pipe is placed in a liquid medium and is under high pressure for some time.

The most common application of corrugated stainless steel pipes is the construction of buildings and structures. In this field, corrugated pipes are used in the creation of hot and cold water supply systems, heating, Underfloor heating, gas supply systems, as well as in the installation of electrical wiring. If earlier, when organizing and carrying out repairs, it was necessary to disassemble almost the entire wall or floor, then with the advent of corrugated pipes, the need for this completely disappeared.

In addition, the use of corrugated stainless steel pipes in the housing and communal services system has become quite common. Here, fittings are used as additional equipment, but nevertheless, the characteristics of corrugated pipes make them almost irreplaceable. For example, dismantling old and installing new structures for various purposes, repairing electrical wiring or installing a chimney. All this has become much easier to do if a corrugated pipe is used as the main material. In addition, such products are increasingly used in agriculture, the food industry and other industries.

 Connection options for corrugated stainless pipes

As noted above, when connecting corrugated pipes, fittings are used. They can be of different types – plastic, metal, reinforced and conventional – the market for the production of fittings is currently very rich. But most importantly, with the help of fittings, you can connect pipes from the same material, or from different ones. Moreover, with the use of fittings, it is possible to connect corrugated and traditional metal pipes, as well as pipes of different diameters.

Please note that corrugated pipes and fittings are produced in different countries. If the most famous and most commonly used are corrugated pipes made in South Korea, it is impossible to find fittings from this country. This is due to the lack of their production in South Korea. However, fittings are manufactured in many other countries, so finding the right product for you is not a problem.

Despite the large number of manufacturers of fittings, all their products, in fact, are homogeneous. Moreover, we are talking not only about the material from which the fittings are made, but also about their appearance, which includes the following elements:

• Cap nut and housing;
• Locking ring made of metal or durable plastic;
• High quality silicone gasket

 Connecting the pipe with a fitting is quite simple. To do this, insert its end into the hole in the fitting and clamp it with a cap nut. The presence of a silicone gasket will prevent leakage of liquid from the pipe, and the locking ring will prevent deformation of the finished structure, which can occur during the operation of pipes at high pressure or extreme load.

Despite the variety of fittings, as already noted, their design is of the same type. In addition, they all function on the same principle. Connect the pipes using the fittings do not pose any difficulty. Even if you have no experience in this field, you can watch videos about the installation process and you will understand everything.
