welded pipe machinery

Welded pipe machinery is one of main products of  Company. We could provide production line based on customer's requirements. There are two forming methord of the ERW pipe line.  One is Cage Forming Machine and another one is FFX forming Machine. The biggest different is the SSF has better performance when the thickness of pipe is thicker.

We have the ability of design, manufacture, erection and commissioning. The most important we can ensure the good service after-selling. Our equipments have been exported to Germany (Cut-to-length line), India (hydrotester and end beveling machine), Spain (whole spiral pipe mill), Malaysia (whole spiral pipe mill), South Africa (ERW) etc. One of the attachments is our customer reference and machines pictures. It can prove that we are experienced with overseas project.

Welded Pipe Making Machine

Something about Welded Pipe Making Machine
1.This kind of production line is mainly used for manufacturing welded pipes, especially for stainless steel pipe,carbon mild steel pipe,metal iron, copper,alumium steel pipe and so on.

2. The finished pipe shape decided on tube mould.

3. Widely used in industry and decoration,such as:chemical,building,office and household furniture,stair handrail etc.

4. Our main product: industrial pipe making machine,decorative pipe making machine

Carbon steel tube mill is designed to produce round tube diameter of  32-100mm
Wall thickness : 1.5-4.5mm (carbon steel)
The Carbon steel tube mill is designed for forming pipes and tubes on one continuous line with steel strip, which was slit by slitting line to fit pipe or tube diameter. Using high frequency induction heating, this line is capable of producing section material of various diameters and sizes by squeezing weld seam together into closed shape.
