Medium-pressure steel wire reinforced plastic pipeline and pipe fitting connecting method

Abstract

The invention discloses a medium-pressure steel wire reinforced plastic pipeline and a pipe fitting connecting method. The medium-pressure steel wire reinforced plastic pipeline comprises pipes (1, 1' and 1''), inner bushings (2, 2' and 2''), fastening sleeves (3 and 3'), sealing rings (4, 4' and 4'') and connecting members (5, 5' and 5''), wherein the inner bushings (2, 2' and 2'') are arranged inside ports of the pipes (1, 1' and 1'') for supporting; the fastening sleeves (3 and 3') are fixed on the surfaces of the ports of the pipes (1, 1' and 1'') through a buckling device; the sealing rings (4, 4' and 4'') are sleeved at the ports of the pipes (1, 1' and 1''); and the connecting members (5, 5' and 5'') are connected to the fastening sleeves (3 and 3') or directly used for fastening the pipes (1, 1' and 1''). According to the medium-pressure steel wire reinforced plastic pipeline and the pipe fitting connecting method which are disclosed by the invention, an engineering medium-pressure pipeline and construction connecting scheme is developed, and the problem of pipe fitting connection in the application of the heavy-caliber high-pressure steel wire reinforced plastic pipeline is solved; and the caliber of the pipeline can reach 400mm, and the pressure can reach 10Mpa. The medium-pressure steel wire reinforced plastic pipeline and the pipe fitting connecting method can be better applied to engineering environments with high requirements, such as emergency transportation and the like.

Description

technical field [0001] The invention relates to a medium-pressure steel wire reinforced plastic pipe and a pipe fitting connection method, which can be well applied to engineering environments with high requirements such as emergency transportation. Background technique [0002] Steel wire reinforced plastic pipe is a new material pipe product independently developed by our country. Based on the manufacturing experience of traditional metal and non-metal composite pipes, the plastic main body and metal skeleton are organically combined into an overall reinforced structure, which retains the flexibility of plastic pipes. At the same time, the strength of steel material is introduced, and the advantages of plastic material and metal material are brought into full play. Due to the many advantages of steel wire reinforced plastic pipes, it has been widely used in engineering construction in recent years. Its performance is very good to meet the construction of municipal and indu...
