Product Description

Welding Tube moulds,tube forming rollers,weld pipe die
Product Details:
The main products of our company include welding pipe roll die and cold roll forming die.Based on the demand of customers,our company undertakes various round pipe,cold roll formed,round-square,directly square,double curved surface straightening roll and double involute die,etc. with materials of GCr15, cR12, Cr12MoV, SKD11, D2, Cr12Mo1V1, 3Cr2W8V, H13, 9Cr2Mo, and wear resistant RE high chrome cast iron.
Round pipe die covers various sizes of dia 8-711mm,and the side of square pipe die can be as long as 600mm.
U-shaped die can be 630×432×6,while U-shaped,T-shaped,Z-shaped and V-shaped steel piles can also be made.
Our company also designs and manufactures abnormally shaped dies of shapes according to customers' requirements.

Our Advantage:
A.Advanced groove deformation technology
After  years  of  practice  and  exploration,  our  company   starts  from  the corporate   status  quo,  using  a
combination   of molding   concept,  that  one  set  of  rollers  can  produce  dozens   of standard   square  and
rectangular tube, to  achieve roll change  not unloading roll  axis, the change time  is greatly reduced,  the unit
performance greatly improving , roll costs being reduced .

B.Strict raw material control

1.Germany imported portable spectrum analyzer  
(Handheld * Fluorescence BRUKER SI TITAN MODE1600 ) Inspect the chemical composition of raw materials.
2.Metallurgical Microscope MV6000
Monitor the  transformation process  of the  fiber tissue  before and after heat treatment quenching
3.Germany   imported   desktop  direct   reading   optical spectrum analyzer
Inspection of the chemical composition raw materials
4.Digital ultrasonic flaw detector
Flaw detection for the raw materials, heat-treated roll, finished products before shipment.

C.Professional heat treatment technology
Unique heat treatment technology gives full play to comprehen-sive mechanical property of the  material, and the roll has better
characteristics of  wear resistance, durability and  fatigue resis-tance.
During  heat  treatment  process,   computer  control  is  applied(±1°)to ensure quenching quality.

D.Excellent equipment is an important guarantee to make quality rollers.



E.Roller quality was widely praised by users due to its strict quality standard and meticulous product inspection.
