Abstract
The invention discloses a lined stainless steel pipe joint. The lined stainless steel pipe joint comprises a joint body, wherein the inner wall of the joint body is provided with a protective layer; the protective layer includes an anticorrosive coating and a heat-resistant layer; the anticorrosive coating is arranged on the top of the heat-resistant layer; the anticorrosive coating includes a graphene epoxy zinc rich coating layer, a zinc silicate coating layer and a polytetrafluoroethylene coating layer; and the heat-resistant layer comprises a silicone resin layer, a phenolic resin layer and a hydrogenated butyronitrine resin layer. By means of the lined stainless steel pipe joint, through the cooperation of the joint body, the protective layer, the anticorrosive layer, the heat-resistant layer, the graphene epoxy zinc rich coating layer, the zinc silicate coating layer, the polytetrafluoroethylene coating layer, the silicone resin layer, the phenolic resin layer and the hydrogenated butyronitrine resin layer, the problem that the service life of an existing stainless steel pipe joint is affected due to the different transmission mediums in use is solved, so that the maintenancecost is reduced, and the practicability of the stainless steel pipe joint is improved.
Description
technical field [0001] The invention relates to the technical field of stainless steel pipes, in particular to lined stainless steel pipe joints. Background technique [0002] Stainless steel pipe is a hollow long round steel material, which is widely used in petroleum, chemical, medical, food, light industry, mechanical instrumentation and other industrial pipelines and mechanical structural components. At the same time, it is light in weight, so it is widely used in the manufacture of mechanical parts and engineering structures, and is also commonly used as furniture and kitchen utensils. [0003] Stainless steel pipes are widely used in daily life. When connecting stainless steel pipes, stainless steel pipe joints need to be used. When the existing stainless steel pipe joints are used, due to the difference in the transmission medium, the service life of the stainless steel pipe joints is affected, increasing Reduce maintenance costs and reduce the practicality of stainl...
