TP347H large diameter thick wall φ 711mm*88mm seamless pipe is mainly used in hydrorefining unit projects and ten million tons of refining and chemical integration projects, with the production capacity of a single unit greatly improved, the diameter and wall thickness of stainless steel seamless pipe demand also increased.  Its process route is round steel, hot perforation, cold rolling, heat treatment,[TJC STEEL] inspection and test.  The TP347H φ 711mm*88mm pipe produced by the above process can meet the needs of various devices, especially high-pressure hydrogenation units.  

 

N08367 large diameter thin wall φ 711*11mm seamless pipe is mainly used in the field of nuclear power, with the trend of nuclear power, seawater cooling system seawater pipe due to long-term contact with seawater, more prone to local spot corrosion perforation, cracking phenomenon, N08367 as corrosion resistant seawater medium material,  Its high strength and corrosion resistance make it the best alternative to conventional duplex steel and expensive nickel-based alloys.  Its process route[TJC STEEL] is round steel, re-inspection, peeling, perforation.  Inspection, grinding, pickling, inspection, lubrication drying, cold rolling/drawing, degreasing, heat treatment, straightening, pickling passivation, finished product inspection, identification, packaging, shipping.  The N08367 φ 711mm*11mm pipe produced by the above process meets the requirements of the standard and technical conditions, and the comprehensive evaluation of corrosion resistance is h
