9Cr2Mo Material Pipe Making Equipment Molds Steel Duct Mill Rolling
Dies Tube Roller Spacers
Product Profile
Welded pipe mould tube roller die is a necessary hardware accessory
for manufacturing metal straight seam welded pipe. Under the action
of the external force of the welded pipe mould, the steel coil is
gradually forced to be cold rolled and curled in the arc of the
tube roller, and then welded to obtain the closed welded pipe.
Usage
Welded pipe molds are used to produce stainless steel profiles,
copper, aluminum, and iron profiles, as well as high-frequency
welded pipes. The quality of the roll determines the quality of the
product.

About Us
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.
