In the past few years since I entered the industry, the demand for large-diameter longitudinal welded pipe, especially industrial welded pipe, is increasing every year. Otherwise, more and more welding pipe enterprises will not transform to produce large-diameter longitudinal welded pipe. What are the production methods of large-diameter welded pipe? Today, we GXG technology will take you to know.

The production mode of large-diameter longitudinal welded pipe is usually based on continuous production mode and intermittent production mode. Continuous production mode is to use pipe welding machine for continuous production and process steel coil into welded pipe. This investment is relatively large, because the price of a large pipe welding machine often needs more than one million, which is a great burden for many enterprises, But the efficiency and stability of production are OK.

The intermittent processing method is to use the bracket welding method, first process a section of tubesheet into an unclosed tube, and then move it to the bracket for welding, so as to obtain a welded pipe. This operation is not high in cost investment, but the efficiency is not high enough, the welding stability is not so good, and there is a great chance of pipe damage at both ends of the pipe.

No matter which way you use to produce large-diameter longitudinal welded pipe, you need to start according to your actual situation.
