Tube forming & welding line


TIG Pipe welding technology and high-frequency Pipe Welding technology are the two important solutions for production metal pipe in the present market. With our engineers so many years experience in this roll forming industry, we have full ability to supply the right solution according to the client requirements or production sample.

HF-Longitudinal Tube Welding Lines Brief Introduction
Carbon steel pipe welding machine (HIGH FREQUENCY WELDING) or High-frequency longitudinally welded pipe production line is mainly used for the production of welded steel pipe of φ8 ~ φ610 mm and wall thickness of 0.5~ 20mm as well as the production of square, rectangular, and other custom seamless pipe profile. The line can manufacture welded pipes with good quality machining and high precision assembling at high speed.

If clients never mind the line speed, the argo arc welding style pipe forming and welding machine is the best choice for the thin wall welding profiles, because of its high welding quality and low cost, it is very popular in the market. The speed is 8-15m/min.

Manufacture of TIG-welded tubes
Tungsten-inert gas welding presents itself, in spite of competitive Laser welding, as an interesting alternative for the manufacture of high quality tubes. This technology is comparatively easy to master and the investment costs are low.
As with all other welding processes, the rollforming machine transforms the flat sheet metal into a tube. During the welding phase, an electric arc burns inside a protective gas covering (Argon-Helium mixture or pure Helium) between a non melting tungsten cathode and the strip edges. Multi-cathode welding torches are used when it is necessary to increase the welding speed or when producing tubes of large dimensions. Direct or alternating current is used according to the application in question.
DREISTERN supplies outstandingly successful TIG-welding installation for thin-walled stainless steel tubes or for aluminum-plastic composite tubes.
