High Strength Steel Construction Tubes High Productivity Direct Square To Square Pipe Mill
ERW Tube Mill with Turks-head Forming Technique Introduction:
Advantage of Turks-head Forming Technique:
1. Save rollers: part of the molds can be commonly used. Especially for square & rectangular pipe.
2. The Turks - head can be rotated, so the welding seam can be put in any position of the pipes.
3. It can prevent the surface of pipe from scratching.
4. The max thickness of the round pipe and square pipe can be same. (The upper limit of thickness for square pipe is always 1 mm
less than round pipe's using round-to-square forming method)
5. The production shape is much better, the shape of square & rectangular pipe is very neat.
6. The Turks - head put 4 sides of force on the pipe at same time, which can reduce the wear and tear of the mill, protect the tube mill,increase the using life.

Square Tube Mill Auxiliary Machines:
Customers can trust us to buy the auxiliary machines. Our choice of suppliers for the auxiliary parts is made after 22 years of experience.
Un-coiler
Function: Used for supporting strip steel coil and open it as strip steel so as to make preparation for the pipe forming process.
Shearing butt welding
2 Types: Automatic & Manual
Function: Shear & end welder parallel cuts the head of the strip coming out of uncoiler and the tail of the strip steel going into the accumulator, and weld them together to form a smooth and continuous line of strip steel.
Strip Accumulator
Function: Accumulator is used to accumulate strip steel from uncoiler and provide strip steel to forming unit. It leaves time for the shear & end welder for strip welding and stores certain amount of strip for continuous forming.
Solid State High Frequency Welder
Function: The welder is used for welding edge heating with high-frequency heating device. The whole set of solid-state H.F welder comprises of rectifying cabinet, inverter, output cabinet, connecting optical fiber, closed loop water cooling system, central operator console, and mechanical adjustment device.
Saw Cutting System
Function: Flying saw is used to cut tube during static and motion status in continuously production into desired length.
Straightening Machine
Function:Straightening machine is a finishing equipment for the high-frequency straight seam welded pipe production line, which is used to straighten the steel pipe to eliminate the stress and bending after the steel pipe forming and welding.
Company Introduction
FAQ:
Q:Are you manufacturer?
A:Yes,we are manufacturer. We have 4 factories ( Machining, Assembling, Heat treatment, and
Moulding ). We also have our own R&D department. Welcome to visit us.
Q:What kind of payment term do you do?
A: We do T/T and L/C.
Q:What info do you need before giving me the price and proposal?
A: Since we design individual machine based on our customer's requirement, we need your desired
products' basic dimension, including all the pipe diameter(or tube length), thickness range , usage,
raw material steel grade, coil weight, and degree of automation.
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
solve the raw material (steel coil) purchase, worker training, international market price, and more.
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 pipe making machines for more than 20 years. We have constructed many
steady trading partners in Asia,Africa, middle east, Europe, and South America throughout the years.
Our innovative designed production line and each single unit of the production line are not only
economical but also practical.
