What tests need to go through in the SPA-H bar production process

Beijing machining center has more than 1000 employees, including 360 technicians, 28 engineers, 6 senior welders, 15 professional welders, 52 bachelor's degree, 3 doctor's degree, and 8 R & D team. It is a professional SPA-H bar production team combining theory and practice. With an annual output of 80000 tons, looking forward to the future, our company continues to strengthen the advantages of SPA-H bar leading suppliers in the four steel fields of steel plate, steel pipe, stainless steel and special steel.

High quality pipeline steel plate is the key material for ERW line pipe, LSAW line pipe and SPA-H bar SSAW line pipe. It is widely used in oil, natural gas and water transportation pipeline construction, and can be used for manufacturing pressure fluid transportation construction.

The yield strength of Q690D steel plate is 690 Mpa and the impact temperature is - 20℃. SPA-H bar, Q690D steel plate has high strength, good plasticity and toughness, good weldability and good cold and hot performance. Q690D steel plate is mainly used to manufacture various large engineering structural components and construction machinery. Because of its high strength and good toughness, Q690D steel plate can reduce the self weight of components and meet the requirements of large-scale and lightweight engineering components and equipment under the condition of ensuring strength, stiffness and reliability.

Although SPA-H bar, low carbon steel has excellent plasticity, toughness and processing technology, its strength is low and its corrosion resistance is not strong enough. On the basis of ordinary low carbon steel, the low alloy structural steel with high strength, high toughness, good weldability and corrosion resistance can be obtained by adding a small amount of alloy elements and the total amount is less than 3%. Manganese is the main additive element in this kind of steel, and its content is about 1% ~ 1.6%.

10CrMo9-10 seamless pipe implements European standard EN 10216-2. The chemical composition of 10CrMo9-10 seamless pipe: C 0.08-0.14, Si ≤ 0.50, Mn 0.30-0.70, P ≤ 0.025, S ≤ 0.020, Cr 2.00-2.50, Ni ≤ 0.30, Mo 0.90-1.10, Al ≤ 0.04, Cu ≤ 0.03. The mechanical properties of 10CrMo9-10 seamless pipe: tensile strength: 450-530 MPa, yield strength: ≥ 280 MPa, elongation: ≥ 22%, impact energy: ≥ 40J. SPA-H bar, 10CrMo9-10 seamless pipe is a kind of high temperature and high pressure boiler steel, which is mainly used in the production of power station boiler, steam boiler equipment, pressure vessel, large pressure pipe, etc.
