Seamless steel pipe 65x10mm GOST 8732 st 20 is a hot-rolled metal-roll made of steel, with a ring-shaped cross section. Pipes are produced by piercing a solid heated round billet on a special press. The resulting sleeve is then rolled out on rolling mills, forming the required diameter and wall thickness. The seamless hot-rolled pipe has a special strength, it is able to withstand significant mechanical loads and increased pressure of the working environment. Hot drawn pipes are manufactured from 16 mm to 720 mm in diameter with a wall thickness of 4 mm.


Seamless hot-rolled carbon steel tubes can withstand pressures of 16MPa. Structures and pipelines created from this solid rolled metal are very reliable, durable and resistant to external influences.


Due to the homogeneous surface structure, such pipes without welds can be processed by various metalworking methods, they are easy to rivet and cut, bend and drill. They are perfectly connected by electric welding, and withstand a pressure of 16 MPa. Due to its good performance, this seamless pipe is used in various industries. The price of this material allows you to create from it extended configurations of pipeline systems and overall metal structures.


This rolled product is needed in construction and mechanical engineering, it is used in the oil and gas industry and at chemical enterprises. Such a durable and reliable material is needed wherever it is necessary to prevent leakage of the working substance from pipelines.


       You can buy Seamless steel pipe 65x10mm GOST 8732 st 20 from us at the best price in Ukraine. A wide range of products allows us to quickly and efficiently fulfill any order, helping to complete any construction work on time.
