Abstract

The invention discloses an inner lining stainless steel pipe fitting joint. The inner lining stainless steel pipe fitting joint comprises pipe bodies, a first clamping plate, a second clamping plate and a sealing ring, wherein a first connecting hole is formed in the front face of the first clamping plate; a first connecting block is transversely and fixedly connected to the left side of the outersurface of the first clamping plate; and a first fixing block is transversely and fixedly connected to the right side of the outer surface of the first clamping plate. Through the cooperation of thefirst clamping plate, the second clamping plate, the sealing ring, the first connecting block, a first sealing gasket, a first placing groove, the first fixing block, a second sealing gasket, a secondplacing groove, a second fixing block, a second connecting hole, a semi-threaded bolt, a nut and a third through hole, the joint of the two pipe bodies can be effectively connected and sealed, and the maintenance of a pipeline by a maintainer is facilitated; and meanwhile, the problems that a joint of a traditional flange connection mode cannot be reused and resources are wasted are solved, and the inner lining stainless steel pipe fitting joint has the advantage of secondary utilization and is worth popularizing.

Description

technical field [0001] The invention relates to the technical field of pipe joints, in particular to a lined stainless steel pipe joint. Background technique [0002] The lined stainless steel pipe is a bimetallic pipe made of carbon steel pipe as the base pipe, which is combined with the stainless steel lined pipe and the base pipe through the reduction method, cold expansion method, deflagration method or brazing method, and the traditional connection of the lined stainless steel pipe Different methods are divided into welded connection, threaded connection and flange connection, etc. However, when the steel pipe body is damaged and needs to be replaced in the traditional flange connection method, it is not convenient to connect the pipe body and the steel pipe because the flange plate and the steel pipe are welded. When the flange is disassembled, the damaged pipe body and the flange joint can only be replaced together, resulting in a waste of resources. Contents of the...
