ASTM A333 Gr.7 seamless steel pipe has hollow cross-section, which is widely used for transporting fluid, such as oil, natural gas, gas, water and some solid materials.
Compared with solid steel such as round steel, ASTM A333 Gr.7 seamless steel pipe is lighter in weight when bending and torsion strength is the same. ASTM A333 Gr.7 seamless steel pipe is a kind of economic section steel, which ASTM A333 Gr.7 seamless steel pipe is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipe, automobile transmission shaft, bicycle frame and steel scaffold used in construction.
