The welded pipe equipment for producing thick pipe and thin pipe can be the same, but the design requirements for the welded pipe mould are not the same. If you change or remain unchanged a little, there will be a big difference in the use effect. Here's the differentiation of the first group.

Why do we talk about the first group of welded pipe moulds? This is because we get such a phenomenon in our daily work and customer feedback, that is, the first group of welded pipe moulds often do not arc, or the same design, which can be used in this company, but after changing to another company, the effect will not work. This involves two problems, One is the problem of design, and the other is the problem of using habits of welded pipe workers. Let's talk about the problem of design. The design of the first group of dies for thick pipe and thin pipe is slightly different. For thin pipe, we need to press the die down so that the arc can be started. If the die can not be pressed down, then the edge can not be warped, that is, the arc can not be started. However, for thick pipe, the die at the same arc position can not be started, because the die can not be pressed down or pressed down, The arcing is too big. That's why the mold design of welded pipe is different for thin pipe and thick pipe with the same size.

This is just one of the design factors, as well as strength factor, quantity factor and so on. Each factor can put forward different requirements for the design of welded pipe mould, so the design of welded pipe mold is not simple.
