Longitudinal Zhenjiang, also known as welded steel pipe, steel plate or strip is formed by the coil is made of steel after welding. But less than ordinary strength seamless steel pipe, welding processes because of their differences into stove pipe, welding (ERW) pipe and automatic arc welded pipes. End of its round shape is divided into pipe and shaped (square, flat, etc.) pipe. 
 Professional distribution of various sizes and materials welded steel pipe, spiral welded pipe, thick-walled pipe, large diameter pipe, straight seam welded pipe, galvanized pipe, high frequency welded, non-label pipe, inch pipe and other pipes 

 Material Range: Q235 Q345b Q195 q215, etc. 
 Process: Electric arc welding gas welding resistance welding furnace 
 Specifications: Diameter: 15-820mm thickness :8-30 (special specifications and standards can call to order, also can produce British standard pipe) 
 Common standards: GB/T3091-2001 GB/T14291-2006 GB/T12770-2002 GB / T 3091-2001, etc. 
 Advantages: light, do not see the weld, remove the lubricant inside the burr can be electroplated.
