Get to know about Stainless steel pipes: varieties, types and its advantages

The problem with most metals is their high susceptibility to moisture. That is why pipes made of iron or steel are rarely used in construction today.

However, metals have one advantage over other materials - high strength. The solution to the problem with the appearance of corrosion on pipes can be called the use of stainless steel.

Popularity of stainless steel pipes:

The main performance characteristics determine the popularity of stainless steel pipes. Today they are used in a wide variety of industries. Of course, plastic pipes are most often used in everyday life, but in some cases only pipes made of this steel are suitable for installation work.

The cost of the product in question depends on the following points:

• Used steel grade. The peculiarities of the applied production technology determine the steel grade, which also determines the performance.

• Geometric parameters: wall thickness, wall length, section shape. The complexity of the production technology, as well as the amount of material used, depends on the geometric parameters.

• Manufacturing method used. There are many methods for the production of stainless steel pipes; the cost of production depends on their characteristics.

• Isolation available. Some products are supplied with an insulating layer that significantly increases the service life of such pipes.

• Pipes are selected according to the permissible indicators of mechanical stress and chemical attack.

Section geometry

When choosing pipes, the first thing to pay attention to is the geometry of the section. During construction, a profile pipe is often used. The section geometry determines the main performance characteristics:

• The complexity of the installation work.

• The effectiveness of the system being created.

• Product cost.

Note that pipes of the same geometry can be produced in a variety of ways, which determines the marking, product cost, and other performance characteristics.

Round section

The most widespread are pipes with a round profile due to the fact that this shape has the highest aerodynamic performance. The production of pipes with a circular cross-section can be carried out using coiled sheet steel or using seamless technology.

Electric-welded round pipes are divided into the following groups according to the production method:

• Straight seam.

• Spiral seam.

• Straight seam can be characterized by the fact that they can withstand a small load.

Pipes in which the seam is represented by a spiral can have a diameter from 530 to 1420 mm.


various areas of industry, road construction, the creation of industrial pipelines. They can be conditionally divided into the following groups:

1. General purpose.

2. For use in the construction of oil and gas pipelines.

3. Creation of highways.

Straight seam versions have a diameter of 16 to 1,420 mm. They are conventionally divided into the following groups:

1. To create highways.

2. General purpose.

3. For laying oil and gas pipelines.

Considering pipes that have seams, we note that despite the improvement of production methods, it is the place of metal connection that has the least strength: the joint is the place of concentration of the load. To increase the strength of pipes, a seamless production method was developed.

The seamless design is characterized by the fact that it has the same strength index along the entire length. The peculiarities of this production method are that the product is obtained by pulling it out of a hot billet. In addition, the cold rolling method can be used, which has quite a few features.

The pull method is more suitable for the production of small diameter pipes. This is due to the peculiarities of the production technology. Large diameter products are produced by cold rolling. Seamless pipes are often used in the petrochemical industry because of the high demands placed on such pipelines.

The profile version of the pipes is characterized by the fact that it has a rectangular, square or oval cross-section in cross section. Increased resistance to deformation and corrosion leads to widespread use in construction. When using steel with a high thickness index, the resulting product is quite durable.

The most common cross-sectional shapes of a profile pipe are:

1. Square: In the production of this version, hot-rolled strip is used, which is supplied in accordance with GOST 8639-82. Section sizes vary from 15 by 15 mm to 300 by 300 mm. Pipes of this type are used to create supports, posts and frames. Large square pipes are suitable for a wide variety of construction work to create structures that will be subjected to mechanical stress.

2. Rectangular: Rectangular stainless steel pipes are manufactured in accordance with GOST 8645-68. The section is classified by size into small (from 20 by 10 mm to 50 by 40 mm), medium (from 60 by 30 mm to 120 by 80 mm), large (from 140 by 60 mm to 200 by 100 mm). Rectangular pipes are more popular than square pipes. This is due to the lower cost, as well as the ability to distribute the load.

3. Oval: Oval pipes are quite rare, mainly used in the creation of ventilation systems. The oval shape defines uneven load distribution.

Today on the construction market there is a huge number of varieties of profile pipes, which allows you to choose the most suitable design options.
