For conventional pipe welding equipment, the arrangement is generally 3314 or 4414, but for some pipes with specific production requirements, the arrangement is not like this. For example, for thick wall pipe welding equipment, the arrangement of sizing sections is more. So why should there be more groups of Sizing Sections of thick wall pipe welding equipment?

The design of thick wall pipe welding machine is different. Since it is thick wall pipe, it is not easy to form, so it needs slow forming, and slow forming corresponds to lengthening the layout and designing more deformation groups to achieve the deformation effect. Generally, the sizing section of thick wall pipe is designed for at least 5 groups of archways, and some even reach 7 groups, so as to meet the deformation needs of thick wall pipe.

If the pipe you produce is thick wall pipe, you must check the number of groups in the sizing section. If it is less, it will certainly affect the production. It is better to change the design and improve the forming effect.
