The invention discloses a stainless steel clad plate-welded steel pipe, and relates to the technical field of a steel pipe. The stainless steel clad plate-welded steel pipe comprises a steel pipe body, and the steel pipe body comprises a stainless steel layer, a fire protection layer, an insulating layer and an inner layer. The left end of the outer surface of the steel pipe body is in threaded connection with a first threaded sleeve, the left side of the first threaded sleeve is fixedly connected with a first ring flange, and a limiting groove is formed in the left side of the first ring flange. The outer surface of the steel pipe body is detachably and fixedly connected with a first fixed block, a first connecting groove is formed in the top of the first fixed block, and a second connecting groove is formed in the top of the first fixed block. The right end of the outer surface of the steel pipe body is in threaded connection with a second threaded sleeve. By the structure of the first threaded sleeve, the first ring flange, the limiting groove, the second threaded sleeve, a second ring flange, a limiting strip and threaded holes, the steel pipe body can be conveniently mounted.
Description
technical field [0001] The invention relates to the technical field of steel pipes, in particular to a stainless steel composite plate welded steel pipe. Background technique [0002] Steel pipes are used to transport fluids and powdery solids, exchange heat, and manufacture mechanical parts and containers. The manufacture of ships, boilers, and aircraft, the manufacture of thermal power boilers after World War II, the development of the chemical industry, and the drilling and transportation of oil and gas have all vigorously promoted the development of the steel pipe industry in terms of variety, output and quality. [0003] At present, the existing stainless steel composite plate welded steel pipes on the market have the disadvantages of inconvenient installation and lack of fire protection and heat preservation. The existing stainless steel composite plate welded steel pipes are generally made of pure stainless steel, which not only consumes materials, but also has a sing...
