从China供应商批发进口Api 5l Welded Steel Pipes — FOB条款

Welded pipes is steel plate or steel belt, and the surface is a pipe with welding ribs after cutting, bending, welding and other processes. The main advantages of welded pipes are their lower inherent cost, narrower tolerances for wall thickness, concentricity (OD/ID) and internal surfaces that can be checked prior to manufacture. Welded steel pipe is divided into furnace welding pipe, electric welding (resistance welding) pipe and automatic arc welding pipe because of its different welding forms into straight seam welding pipe and spiral welding pipe two kinds, because of its end shape is divided into round welding pipe and special-shaped (square, flat, etc.) welding pipe. Seamed pipes offer tighter tolerances but thinner wall thickness rather than seamless pipes. Welding pipe can be used for water pipeline, gas pipeline, heating pipeline, electrical pipe and so on.
