Stainless steel pipe large diameter
Stainless Pipe large diameter has increased strength and anti-corrosion characteristics. This is an indispensable element of the oil and gas industry. These pipes are used for industrial containers, organization of the main pipelines and other. The pipes of large diameters are strategic products for our country, a key factor in ensuring the independence of domestic enterprises by the global metal recycling market conditions.
The sheet metal is purveying a shop where the cutting is made and plasma cutting process, then it is delivered to the receiving table further bending machine by rolling it into the shell. Ready-shell welded longitudinal seam welding semiautomatic protected by an inert gas, or the automatic submerged arc welding. These large diameter pipe blanks are checked on the geometrical parameters, the quality of welds and calibrated. Then comes the assembly. Shells dock along the length of several pieces and welded seams in the ring assembly stand. Finished pipes pass the final inspection on the quality of welded joints and the geometric dimensions, after which they issued a certificate of quality.
large-diameter pipe, metal cones and challenges of modern industry are widely used for the main pipelines, industrial containers, casings of pipelines, bridge piers. On welded pipes of large diameter (720 — 900 mm or more), there is a steady demand from refineries, engineering companies, mining and processing plants, and bridge building. They also find their way into sewage systems and, on the key areas of heating systems.
