high pressure flexible rubber pipe joint: 1.Floating flange type high pressure flexible rubber pipe joint: it is composed of colloid and two pieces of flexible flange. Colloid is by the inner layer and the outer layer of synthetic rubber, skeleton nylon cord, pressurizing steel ring, the gas blow molding process after high temperature vulcanization manufacture. It use pressure by the original 1.0MPa ~ 1.6Mpa (mechanical mould manufacturing process) increased to 2.5MPa ~ 4.0Mpa, especially in corrosion resistance, acid and alkali resistance, oil resistance of pipeline can show its special effects and improve the service life.
2. integral flange type high pressure flexible rubber pipe joint: it is by the colloid and two pieces of flange after special processes, using the gas blow molding process, and then through the high temperature vulcanization produced. The pressure from the original 1.0MPa ~ 1.6Mpa increased to 2.5MPa ~ 6.0MPa, especially in valve is connected with the outlet of the pipeline and pipeline in the settlement of the foundation, to prevent the pull off is its special function, and prolongs the service life of the high pressure flexible rubber pipe joint, to the user brought unexpected benefits.
