Materials include:20#, 35#, 45#, 16Mn, 27SiMn, 13CrMo44(A335P12, STFA22, 15CrMo), 12Cr1MoV, 10CrMo910(A335P22, 12Cr2Mo, STFA24), A335(STFA25, Cr5Mo), A335P9(Cr9Mo, STFA26), A335P91(T91), A335P92 (WB36), steel 102 (12Cr2MoWvTiB)Stainless tubes (TP321H, 1Cr18Ni9Ti, TP304H, TP316L, TP347, 0Cr18Ni9Ti), GH3030, GH3039, GH2080, 17-4ph, 0Cr17Ni4CuNb etc.Executive standard: national standard gb5310-95, JISG3457, German standard din17175-79, American standard ASTM, ASME, etc.
The nominal diameter of the pipe is not equal to the inside diameter and the outside diameter, such as Nominal diameter is 100 mm screw steel tube 5, 108 * 102 * 5 several kinds, 108 for the outer diameter of the pipe, said the pipe wall thickness, therefore, the inner diameter of the steel pipe for (108 * 5-5) = 98 mm, it is not completely equal to the difference between the double wall thickness reduction steel pipe diameter and nominal diameter is close to the inner diameter, and is not equal to the inner diameter of a pipe diameter of the specifications of the name, with a nominal diameter in the design drawings, in order to according to the nominal diameter pipes, pipe fittings, flanges, gaskets, etc can be determined structure size and connection size, nominal diameter using sign DN, said using diameter in the design drawing, A table of piping specifications should also be made to indicate the nominal diameter and wall thickness of a particular pipe. Now China's steel production capacity is also surplus, market forces will adjust, the market plays a decisive role in the allocation of resources and better play a role. Some people hope that economic development will be stable all the time, which is the ideal state of the planned economy, but in fact, it cannot be achieved. A lot of economies are wave type development, wave type development just accords with the economic rule. For example, many steel enterprises are losing money now, so they have to close down and turn around. To survive, it is necessary to strive for innovation and development, such as research and development of new products, do everything possible to reduce costs, work hard in environmental protection, transformation and development, and explore the road of transformation and upgrading, China's iron and steel industry can enter a new stage of development.
