PIC-(Information of seamless steel pipes)
Full Information of seamless steel pipes
\
Seamless steel pipes 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 / A53 Gr.B, API5L 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.  

Our comany Produce and full stock for API 5L B, ASTM A106 GRB, ASTM A53 GRB.
