    What are the provisions of the grooved pipe fittings

    Release date:2014-10-15

            The application of groove pipe connection technology makes the complicated pipeline connection process easy, fast and convenient. Make pipe connection technology a big step forward. Groove pipe connection operation is very simple, no special professional skills, ordinary workers after a simple training to operate. This is because the number of products has been part of the technology with fine factory way to dissolve in the finished product. A fitting connection is only a few minutes, the maximum limit of the technical difficulty of the field operation, save time, thus also stable the project quality, improve the efficiency of work. This is also the general direction of the development of the installation technology.
            Groove pipe fittings (clip) should be in accordance with the provisions of the connection?
            One, groove type connecting piece (pipe joint) and pipe trench depth should meet the national standard "automatic sprinkler system - trench pipe connector," the provisions of GB5131.11;
            Two, there are vibration places and buried pipeline should be flexible joints, other places are advised to use rigid joints, when the rigid joints, every 4 to 5 rigid joints should be set up a flexible joint;
            Three, when the mechanical three through, four connections, the size of the opening and the distance between holes should not affect the strength of the open pipe. Usually the maximum pore diameter should be less than 1 / 2 of the hole diameter of the pipe; when the open hole diameter is larger than that of the open hole pipe diameter of 1 / 2, should the card hoop triples, four-way pipe;
            Four, the open hole spacing and the size of the opening, the general should not be less than 2M. groove connection and other types of connection should be used when the conversion connector;
            Five, the groove connecting piece is connected with the pipe diameter, the appropriate use of trench connector reducers; in pipeline elbow shall not use the complement core; when the complement core, tee is available a, four-way should not more than two; nominal diameter greater than 50mm pipes should not be adopted with movable joint;
            Six, when connected by notching grooves, tube wall thickness should be with automatic sprinkler systems -- trench pipe connecting piece "GB5131.11 provisions, when the rolling grooves connected, the tube wall thickness should be with automatic sprinkler systems -- trench pipe connecting piece" GB5131.11 provisions;
            Seven, the groove joints should be the ethylene propylene diene rubber (EDPM) C type sealing ring, good elasticity, installed after pressing the C type sealing ring gap should be.
