Astm A335 P91 24”Sch60 Alloy Seamless Steel Pipe High Pressure Boiler Steel Pipe

 

product description

P91 steel is equivalent to the national standard 10Cr9Mo1VNb. T91/P91(10Cr9Mo1VNb)
Not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness and high and stable durable plasticity and thermal strength properties. When the service temperature is lower than 620℃, its allowable stress is higher than that of austenitic stainless steel. Above 550℃, the recommended design allowable stress is about twice that of T9 and 2.25Cr-1Mo steel.P91 seamless steel pipe has high high temperature strength, excellent anti-oxidation performance and good process performance.

 

Production process
Hot rolling (extruded seamless steel pipe): pipe billet → heating → perforation → three-roll oblique rolling, continuous rolling or extrusion → pipe → diameter (or diameter reduction) cooling pipe straightening → hydraulic test (or flaw detection) marking → storage.
cold drawn (rolled) seamless steel tube billet → heating → perforation → head → annealing → pickling → oiling (copper plating), multi-pass cold drawing (cold rolling)→ billet tube → heat treatment, straightening → water pressure test (flaw detection), marking → storage

 

P91 seamless steel pipe is widely used. It can be used as high-temperature superheater and reheater steel pipes for subcritical and supercritical boilers with wall temperature ≤625℃, as well as high-temperature headers and steam pipes with wall temperature ≤600℃, as well as nuclear power heat exchangers and furnace pipes for petroleum cracking units. With the development of large-scale power generation equipment in the direction of large capacity and high parameters, P91/T91 steel has become an ideal power plant boiler in the temperature range of 600~650℃ due to its high high temperature strength, excellent oxidation resistance and good process performance. steel.
The general-purpose P91 seamless steel pipe is rolled from ordinary carbon structural steel, low-alloy structural steel or alloy structural steel, and has the largest output. It is mainly used as pipelines or structural parts for conveying fluids.
According to different uses, it is divided into three categories: a, according to chemical composition and mechanical properties; b, according to mechanical properties; c, according to hydraulic test. Steel pipes supplied according to categories a and b, if they are used to withstand liquid pressure, shall also be subjected to a hydrostatic test.
P91 seamless steel pipes for special purposes include P91P91 seamless steel pipes for boilers, P91P91 seamless steel pipes for geological use, and seamless steel pipes for petroleum use.
