Construction

ASTM A335 P11 P12 P22 steel pipe is a low carbon steel with specific chemical composition and mechanical property requirements, and its hardness and strength can be improved through different heat treatment methods.

API 5L X70 PSL2 pipes are widely used in the oil and gas industry, including oil and gas fields, refineries, natural gas transportation and other fields.

ASTM A134/ASME SA134 Carbon Steel funnels are reasonable for bowing, for flanging, for welding, and so on.

STPG370 is a low-carbon steel pipe material commonly used in some low-pressure pipeline systems.
