High frequency welded pipe equipment to produce welded pipe forming technology is developed in three stages according to time period and forming method: Roll Forming,Caga Forming, and Flexible Forming Excellent.

High frequency welded pipe equipment welded pipe forming technology includes two parts: rough forming and fine forming. It is the core of high-frequency welded pipe production technology. If the forming quality of the steel strip in the rough forming and finishing stages is not good or the forming is not in place, it is difficult to produce Produce high-quality welded pipes. Therefore, the forming technology determines the output, variety, quality, raw material and roll consumption of the high-frequency welded pipe, which is a matter of great concern to the design and manufacturing department and the user department of the welded pipe equipment.

Let's start to talk about the characteristics of these three molding technologies.

1. Roll forming technology

Roll forming technology adopts two-roll horizontal frame for rough forming and fine forming, and some vertical roll frames are set between the horizontal frames. For larger welded pipes, in order to improve the quality of deformation and reduce the speed difference, the roller adopts a combined roller. Because high frequency welded pipe equipment has fewer space constraints and greater adaptability, it can produce thin-wall welded pipes and is also suitable for thick-wall welded pipes. This roll forming technology has been used for a long time. However, a set of rolls is required for each size of welded pipe. Therefore, the more types and specifications of welded pipes, the greater the number of rolls and the greater the cost. In the absence of a rapid roll change device, the roll change time is very long, and generally requires 1 to 2 shifts of work time, which reduces the production efficiency and increases the product cost. Therefore, it is not suitable for small batch, multi-variety welded pipe production.
