Product Description

Q235 SPHC ERW steel pipe Cutting Chamfer Automotive Welded Steel Tube

 

Application:Dashboard, Seat, Anti-collision Beam, Cylinder Shock Absorber, Door (Thermoform Tube)

 

size:L--2~12m OD--10~76mm WT--0.5~4mmmm

 

Manufacture method:The steel pipe shall be made of hot rolled steel strip or cold rolled steel strip by high frequency resistance welding method

 

Delivery State:Steel tube should be welding or heat treatment state delivery

Surface Quality:The internal and external surfaces of the steel tube are not allowed to have cracks, scabs, folds, delaminations, laps, and burns. Allows for scribes, scratches, misalignment of welds, burns, oxide scales, and external burr removal traces that are not more than a negative wall thickness deviation

 

Advantages: Good mold material, high quality of coolant and other production materials
