Reasons For Wrong Edges Of Thick-walled Straight Seam Steel Pipes

So what is the reason for the misalignment of thick-walled straight-seam steel pipes?

First of all, you should check whether the sickle of the steel strip is bent. The bent sickle is a very important factor causing the edge error of the steel pipe.

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

Then, when the welding height of the steel lead and the tail weld is relatively large, if the weld height of the steel lead and the tail weld is not handled correctly during forming, it is easy to produce a large misalignment. If the lead of the edge steel is not repaired, If the shape and size of the tail are not good, it will easily cause hard bending of the steel strip during the docking process, resulting in misalignment.
If the edge of the strip is not good, it will also lead to edge errors of thick-walled straight seam steel pipes.
