Seamless steel pipe 21x2mm GOST 8734 st 20

Seamless pipe 21x2mm GOST 8734 st 20 is one of the types of rolled metal, widely in demand in construction and when laying communications. The products have no joints, including a welded seam, are completely sealed and are distinguished by the highest strength characteristics. Such products are able to withstand high pressure, including hydraulic, are reliable, resistant to water hammer.

Pipes of this category are often used in the chemical, mining and processing industries, in construction, when laying pipelines, and in mechanical engineering.

Thick-walled, large-section seamless tubing is used to transport liquids and gases under high pressure. Pipes with a smaller wall thickness are more often used for the construction of television and radio poles.

For the production of cold-rolled pipes of a seamless type, structural steels (of various degrees of strength) are used. Rolled steel manufacturing technology includes 2 stages:

calibration of the blank sleeve on a special rolling mill (at this stage, the main characteristics of the products are established - wall thickness and section size);

the billet is processed at a cold rolling mill, where it is reduced to those parameters that are provided by GOST.

Cold rolled seamless pipes are available in various capacities. The choice of rental should be made taking into account this characteristic and the purpose of the purchase.

ADVANTAGES OF SEAMLESS PIPES:

high indicators of reliability and elasticity;

resistance to mechanical stress, pressure;

exposure to various types of processing;

good weldability;

high level of thermal conductivity.
