Welded steel pipe is divided into straight welded pipe and spiral welded pipe according to the form of weld. Classification by production method: process classification - arc welded pipe, resistance welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe. Straight seam welding is used for small diameter welded pipe, while spiral welding is used for large diameter welded pipe; According to the end shape of steel pipe, it can be divided into circular welded pipe and special-shaped (square, rectangular, etc.) welded pipe; According to the material and use, it can be divided into mining fluid transportation welding steel pipe, low pressure fluid transportation galvanized welding steel pipe, belt conveyor roller electric welding steel pipe, etc | Standerd | GB ASTM A53 ASME SA53 JIS DIN |
