The welded pipe production line can meet more requirements of customers in terms of steel pipe specifications and models. The investment is low, but the production efficiency is relatively low, and the annual output is generally 100000~250000 tons.

The straight seam high frequency welded pipe (ERW) of the welded pipe production line is produced by using the pulse current and proximity effect of high-frequency current to heat and melt the edge of the pipe material after the hot rolled plate is formed by the forming machine, and working pressure electric welding is carried out under the influence of the extrusion roller.

Welded steel pipe, also known as welded pipe, is made of thick steel plate or hot-rolled strip by electric welding after being rolled and formed. The production and processing process of welded steel pipes is simple, with production efficiency, many types and sizes, and less machinery and equipment, but the general compressive strength is less than seamless splicing steel pipes.

Classification by production mode: Classification of processing technology - arc welded pipe, resistor welded pipe, (high frequency, low frequency) gas welded pipe, furnace welded pipe.
