According to the production process,square pipe is divided into:hot rolled seamless square pipe ,cold drawn seamless square pipe, extruded square pipe without dimension, welded square pipe. The welded square pipe is divided into: (a) according to the process of an arc welded square pipe, resistance welded square pipe (high frequency, low frequency), gas welded square pipe, furnace welded square pipe (b) according to the weld of straight welded square pipe, spiral welded square pipe Square tube material classification. Square tube according to material: ordinary carbon steel square tube, low alloy square tube. General carbon steel is divided into: Q195, 0215.0235, 0275SS400, 20# steel, 45# steel, etc. : low alloy steel is divided into Q345, 16N, 0390, ST53-2, etc. |
