Thick wall pipe large diameter seamless steel tube, which belongs to the field of the iron and steel smelting. The method is widely applied to forming a process for manufacturing a large-diameter thick-wall seamless steel pipe which meets the quality requirement on a high-quality steel pipe without extra-heavy type forging and pressing equipment by combining a friction welding technology and a push pipe expanding technology of industries of aerospace, automobiles, petrochemical industry, nuclear power, and the like.
Thick-wall steel pipes with a diameter below 700mm are butted into a pipe blank with a certain length by adopting friction welding, and the butted pipe blank is expanded into a demanded specification on a push pipe expanding machine. The large-diameter thick-wall seamless steel pipe which is made of different materials, such as carbon structure, steel alloy structural steel, heat resistant steel, and the like, and has different specifications of the outer diameter of more than 720mm, the wall thickness 20-130mm and the length not larger than 12,500mm can be produced by adopting the method.
Widely used in architectural decoration, such as elevator decoration, luxurious doors, outdoor projects, wall decoration, advertisement nameplates, sanitary ware, ceiling, corridor, hotel hall, shop facade and also used in furniture, kitchenware, food industry, electronic industry, medical equipment, etc.
