alloy steel seamless steel pipe
PIC-(alloy steel seamless steel pipe)
Seamless pipe for fluid transport generally used in water, oil, gas and other fluids, the main conduit for conveying fluid project and large equipment. The main materials are # 10#, # 20, ASTM A106 Gr.B and so on. In addition to the fluid medium such as water, oil, solutions and other liquid media, cement, grain, coal and other solid media, under certain conditions can also flow. Fluid seamless tube fluid tube is one of the most widely used products.
