Negotiation
Note: The sum of the columbium [niobium], and vanadium contents shall not exceed 0.06%. An alternative maximum may be established by mutual agreement between the purchaser and the manufacturer.
As we have different scope and specify different type of pipe, then the manufacturing process and required quality control test and inspection will be different to each other. so ,if you need steel pipe,please tell us the Specifications of yours,we will give you the best price and service!
