Cold rolled seamless pipe
Cold-rolled tubes designed for operation in a wide range of temperatures with a significant differential pressures. They are resistant to corrosion, have an attractive appearance, to meet modern health standards. They have a thinner wall than hot-rolled pipes, while they are more robust and durable than welded pipe. Reliability, durability, possibility of recycling of scrap for recycling, makes these pipes highly profitable.
Almost the only drawback — high price.
GOST 8734−75 regulates the manufacture of steel of cold and warm pipes of General purpose carbon steel or alloy steel. Depending on the purpose of the composition is normalized following GOST: 380−94; 1050; 4543 281 and 19. Technical requirements for steel pipes — defines the GOST 8733−78.

On the production of ships
steel 10 — GOST 1060−80;
Super thin for parts of machinery THAT 14−3-966−80.
Production of industrial and sanitary pipeline. Cold-drawn seamless pipe is relevant in energy, engineering, oil and gas and chemical industries, the military-industrial complex. Often these pipes serve as a template for the production of parts rolling in the engineering and design teams, in the most various spheres of modern economy.
