Cangzhou Bohai Steel Pipe Co., Ltd. production and supply elbow, and cheap. High manganese alloy elbow were used in the fluid flow alloy steel elbow offer more intense impact relatively strong pipeline; elbow nickel steel alloy material often used in high concentrations of oxidizing acids (nitric acid, sulfuric acid) at room temperature, etc. conveying pipe, but in the reduction of acid (hydrochloric acid, sulfuric acid, etc.) in the conveying pipe is badly corroded unless the concentration of hydrochloric acid is low; martensitic alloy elbow below 650 ℃ have higher high-temperature strength, resistance oxidation and corrosion resistance to moisture capacity steel elbow, but poor welding. Therefore, often used in high-temperature steam pipes, water gas pipeline. Implementation of the standards: GB / T12459-2005, GB / T13401, GB / T10752-1999. Cangzhou Bohai Steel Tube Co., Ltd. specializes in the production of alloy steel elbow 12Cr1MoV elbow, unified digital code: A31132. Standard: GB / T3077-1999 12Cr1MoV main features compared with 12CrMoV alloy steel pipe, with higher oxidation resistance and heat resistance. Creep limit strength and lasting value 12Cr1MoV steel is very close, and has a high plasticity in the case of persistent tension; the process of steel with good weldability, but before welding to be preheated to 300 ℃, after welding required in addition to the stress deal with.
