ERW pipe produce progree:
Incoming raw material inspetion,confirm thr raw material is no problem before production.
Cut the steel coil to fit pipe.
ERW the raw marteril to round or other shape of tubes.
Cold drawn the ERW tubes reach a higher tolerance and good mechanical properties.
Test UT ECT flaring tests and flatten testing.
Application:
Dust cover tube
Steering column tube
Oil tank tube
Transmission shaft tube
Automobile front and rear axle tube
Pneumatic pump tube
Director tube
Quick detail:
Product:Precision ERW welded pipes
Material: 1020 Q235 Q195 etc.
Production Technology: ERW + Cold drawn.
(DOM)Drawn Over Mandrel :
The first stages of manufacturing : ERW ,but in the finishing stages : Entire flash weld is removed and the tube is clod drawn over a mandrel.which provides the tube with a better dimensional tolerances,good surface finish and the strongest weld strength achievable.
