High-Frequency Welded Pipe Mill Line

Economically speaking, the capacity of one line has a best range of welded pipe sizes. Therefore, the welded pipe production lines are divided into different models, ranging from small model to big model. In our company, based on our mature and stable technology, we divide the lines into following 15 models: HG20, HG32, HG50, HG60, HG76, HG89, HG114, HG165, HG219, HG273, HG325, HG377, HG426, HG508, and HG610.

Technically speaking, not all welded pipes can be made by one high-frequency straight welded pipe production line, and one line can produce a certain range of welded pipe sizes.

The most common section shapes are round, square and rectangular. Besides common sections, the line can also produce oval, polygon, and various heterogeneous section pipes.

The production line can be classified into four categories ,which are  API standard high-grade oil casing pipe & oil / gas transmission pipe mill (brand new  F.F pass craftswork ),straight-seam welded pipe production lines to produce pipes of small diameter but big wall thickness ,and plain liquid pipe making mill.

The HF straight-seam weled pipe production line is designed to roll different sizes of steel strips continuously into tube blanks through roller and heat them up throught highfrequency induction or direct contract ,and then weld the tube blanks into straight-seam steel pipe.
