Whether it is the production enterprises of welded pipe molds or the welded pipe enterprises using welded pipe molds, many encounter a situation, that is, the welded pipe molds have cracked, so why does this happen and how should this situation be avoided? We GXG technology combined with daily experience to talk to you.

There are two reasons for the cracking of welded pipe mold: one is that the material of welded pipe mold is impure, that is, the material specification is not enough; However, the internal stress of the welded pipe die has changed. Whether it is improper heat treatment or improper use, there will be uneven stress. If there are hidden dangers of these two factors in your mold, there is a great chance that the mold will crack.

Now that the reason is found, it is simple. In terms of materials, select the welded pipe mold materials from large manufacturers, so that there can be a great guarantee in material purity and specification. In the heat treatment, we need to pay attention to the heat. We must not go too far. We must not have insufficient temperature, too high temperature, insufficient time or too long. We must carry out reasonable process processing according to the material properties. Finally, it is daily use. The production of welded pipe mold is specified according to some requirements of pipe materials. It is not allowed to produce thick wall pipe with thin-wall pipe, so the force will be different, resulting in too large internal stress change.

After mastering the production and use links of these welded pipe molds and doing a good job in daily management and control, I believe there will be no cracking of so many molds. If your welded pipe molds have this problem, you can contact our pipe rust steel technology and we will help you deal with it.
