Description




Application:Suitable for mechanical, construction and other structural purposes, and the straight seam welded steel pipe
with an outer diameter of not more than 711mm, can also be applied to general welded steel pipe for fluid transportation
size: L--4~12m OD--5~711mm WT--0.5~5.5mm
Grade:10,20,Q195,Q215,Q213,Q275
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
