Reworking of Steel Tube Product

Focusing on steel tubular products,the resent technology situation and the development assumption con- cerning reworking of steel products are described in the paper.Also briefed here are the characteristics of the steel tube worth reworking,and the reworking methods for such tubes.The remained and out-of-service steel tubes that are left from the society,and still keep their residual service life can be reworked with such methods as reducing,cladding,filling,cutting out and rolling,etc.so as to be turned into new steel products.As a result,the economic efficiency of steel products shall be enhanced.
