A333 GR.4 Low temperature carbon steel pipe
gnee has 14 steel production lines, 10 processing equipment for processing, bending, painting, heat treatment, cutting, drilling, beveling, tempering, surface treatment, complete testing equipment and strong technical force. The annual production capacity is more than 60,000 tons.
A333 GR.4 low temperature seamless steel pipe is made of carbon and other elements silicon, aluminum, phosphorus and sulfur. The tensile strength is 485MPa and the yield strength is 310MPa.
It is worth noting that the carbon content of A333 GR.4 carbon alloy steel pipe is relatively shallow, usually less than 0.5%. Therefore, compared with high carbon pipe steel, A333 GR.4 seamless pipe has excellent weldability and ductility at extreme temperatures. A333 GR.4 alloy pipe is widely used in pipelines transporting fluids due to its excellent low temperature resistance and corrosion resistance, such as pipelines transporting oil, natural gas, natural gas, water and some solid materials.
