Product Details
1. Double heads Decoiler (Hydraulic model)
It is used to support the coil and provide raw materials for the production line. The reel is cantilever type.
2. Shearing & Welder
To connect the strips after cutting the preceding coil tail end and the succeeding coil top end and being welded together by CO2 gas shielding welding to keep the Pipe Welding Line running continuously.
3.Horizontal accumulator
Storage of steel coil, Advantage: The feeding is more stable, without bending, while reducing the resistance of the feeding, it will not cause damage to the galvanized layer surface, and the noise is relatively lower.
4.Forming and Sizing Machine
The steel strip of a certain width is bent into corresponding specifications of round pipe, rectangular pipe or open profile through roll forming.This unit consists of five parts: forming machine, welding machine, cooling part, sizing machine, and straightening machine.
5.High Frequency Welding Equipment
Tube Mill High Frequency Welder is specially designed for straight seam welding.The high power capacitor C and inductor coil L compose current-mode parallel upper-voltage resonance circuit, which doesn’t need output transformer.
6. Cooling
Cool down quickly, Fixed welded pipe shape
7. Cold Flying Saw
Cut pipe, Low inertia DC motor through mechanical transmission device, measuring, calculate and driving saw car at the same speed with the high-speed running pipe, then cut off the pipe with specified length.
8. Run out table(Stacking Packing Machine)
It’s a packaging equipment designed especially for steel pipe industry, which can realize automatic stacking the tubes or pipes into hexagonal or square shapes, and then Automatic bundling, Sloping, Digital Weighter
9.Straightening device
Straightening of finished pipes with sizing, The upper, lower, left and right positions of the vertical roller of the straightening machine can be adjusted to ensure the outer diameter of the finished rigid tube
About Us

A:Yes,we are manufacturer. We have 4 factories ( machining, assembling, heat treatment,and mould factory)And we have our own R&D department. Welcome to visit us.
Q:What kind of payment term you can do?
A: We can accept T/T and L/C.
Q:What info you need before you make the proposal?
A:The pipe diameter , thickness range , usage, raw material steel grade, coil weight and automatic degree.
Q: What should I do if I just start a new business?
A:Contact us immediately ,we provide free consultant for pre-sales service .Also we can help you to solve the raw material (steel coil) purchase,worker training,international market price.
Q:How do you do QA?
A:We have special team to do strict QA,this is one of our strengths:
(1)Every gear box will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for the centering jumpiness.
(3)Every roller will be checked to make sure its in the range of tolerance critical parts will be inspected for all dimensions.
Q:Why I should choose you,what are the differences between you and other Chinese suppliers?
A:We are concentrate on this industry for more than 20 years,and especially in pipe making machines. Our pipe making machine line directly export to Russia,Vietnam,lndia,Indonesia,and many other countries in Asia, Africa, middle east and South America.
