3087 Seamless Steel Tubes yog cov pa roj carbon steel kav uas ua raws li GB 3087 tus qauv rau qis- thiab nruab nrab- siab boilers, featuring tensile lub zog ntawm 410-550 MPa thiab yield zog siab tshaj 245 MPa. Lawv muab cov cua kub zoo heev txog li 450 degree, ua rau lawv zoo tagnrho rau boilers, tshav kub exchangers, thiab siab -kub industrial pipelines.
