Pipe Heat Treatment Machine

Pipe Heat Treatment Machine takes the heating coils as main components, heat up the seam place on pipe or the whole pipe above steel critical temperature, the fine grain appear during this heat-treatment, and the pipe get better performance.

Description

Pipe Heat Treatment Machine For Pipe On The Prodution Line

During welding, compared with other place, the temperature on welding place is much higher. Due to thermal expansion, stress happens on weld-seam place and both the tensile and yeild strength there get down. After heat-treatment on seam place or whole pipe, the performance of the pipe get better.

Pipe Heat Treatment Machine takes the heating coils as main components, heat up the seam place on pipe or the whole pipe above steel critical temperature, the fine grain appear during this heat-treatment, and the pipe get better performance.

On-line annealing of steel pipe welds is an advanced process for the production of high-strength steel pipes, which can eliminate welding residual stress and improve the structure of the structure, so that the weld and its heat-affected zone have the same structural structure, toughness and strength properties as the base metal.

It is widely used in oil pipelines, large diameter steel pipes, stainless steel pipe welds on-line annealing and other high-quality steel pipe manufacturing industries.
