    PTFE Single Ball DN40 PN16 Flexible Rubber Joint Flange

    DN40-DN4000 High Elasticity Flexible Rubber Joint


    Flexible rubber joints are also called shock absorbers, flexible joints, rubber flexible joints, pipe shock absorbers, etc. It can solve the port deviation, axial expansion and misalignment of various pipelines. It is generally used in civil construction water supply and drainage engineering, fire fighting pipeline network pump room unit pipeline acceptance, sewage treatment pipeline connection, high-pressure gas-liquid chemical medium transportation, petroleum, Ship etc. It is the most commonly used rubber joint for pipe fittings in the world today. It has the advantages of reducing pipeline noise, good sealing, light weight, convenient installation and maintenance, and long service life.


    Craftsmanship


    The vulcanization technology is used to transform the linear molecular structure of the plastic rubber into a three-dimensional network structure. The inner layer is glued, the middle layer is reinforced with SNT series nylon 66 ultra-high-strength industrial silk cord fabric, and the outer rubber layer is composited with rubber curved spheres by injection pressure vulcanization. It consists of cast iron and forged metal flanges.


    Folding performance characteristics


    1. Small size, light weight, good flexibility, easy installation and maintenance.

    2. It can produce lateral, axial, and angular displacement during installation, and is not restricted by the non-through-core pipes and the non-parallel flanges.

    3. It can reduce the transmission noise of the structure while working, and has a strong vibration absorption capacity.
