Abstract

The invention discloses a durable seamless stainless steel tube, which comprises a hollow seamless steel tube body, wherein an inner zinc-plated layer is arranged on the inner wall of the hollow seamless steel tube body; an inner passivation film protection layer is arranged on the outer surface of the inner zinc-plated layer; an outer zinc-plated layer is arranged on the outer wall of the hollow seamless steel tube body; and an outer passivation film protection layer is arranged on the outer surface of the outer zinc-plated layer. Due to the mode, the durable seamless stainless steel tube is suitable to be used as a fluid pipeline, is high in strength, is difficult to corrode and is durable.

Description

technical field [0001] The invention relates to the technical field of seamless steel pipes, in particular to a durable stainless steel seamless steel pipe. Background technique [0002] Seamless steel pipes are widely used in industrial production, urban construction and other fields. The seamless steel pipe has a hollow section and is widely used as a pipe for conveying fluid. Compared with solid steel such as round steel, the steel pipe is lighter in weight when the bending and torsional strength is the same, and it is an economical cross-section steel. Existing seamless steel pipes have the disadvantages of being easily corroded and not durable when used as fluid pipes. Contents of the invention [0003] The technical problem mainly solved by the present invention is to provide a durable stainless steel seamless steel pipe, which can solve the problems existing in the prior art, is suitable for use as a fluid pipeline, has high strength, is not easily corroded, and is...
