Precision Work Oval Pipe Forming Mould D2 Material Roller Spacers
Forming & Sizing Rollers with Cr12 Material
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.
Heat treatment way: There are four heat treatment way for your choose.
(1) Vacuum Heat Treatment :HRC 61-63
(2) Black treatment: HRC61-63
(3) Nit riding treatment: HRC61-63
(4) Vacuum Gas Quenching and Subzero Heat Treatment:HRC63-65
Warm reminding: Tube diameter≥133mm, HRC:58-61
Different heat treatment way , different price!
Tube Roller Process:
raw material - sawing material - rough processing - Drilling - fine finishing - roller polishing - Typing Code - semi-finished product inspection - heat treatment - grinding hole - horizontal die-cutting keyway - quality inspection - oil cleaning - the packaging

Tube Roller Packing :
(1) Rust-proof oil should be added to the export tube roller mold before removing the stains.
(2)Packing in wooden boxes, lined with paper and cloth, to avoid bruising, then use shockproof membrane.
(3)The most outboard wooden packing, all the goods shipped by sea require fumigation wooden boxes.
Q: Are you the manufacturer?

Q: What kind of payment term do you do?
A: We do T/T.
Q: What info do you need before giving me the price and proposal?
A: Since we design individual machines based on our customer's requirement, we need your desired products' basic dimensions, 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 a 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 a special team to do strict QA, this is one of our strengths:
(1)Every gearbox will be tested for 8 hours with oil inside to guarantee there is no leak.
(2)Every shaft will be inspected for centering jumpiness.
(3)Every roller will be checked to make sure it's 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 concentrating on pipe-making machines for more than 20 years. We have constructed many steady trading partners in Asia, Africa, the middle east, Europe, and South America throughout the years.
