Groove pipe connection technology is also called card hoop connection technology, has become the liquid and gas pipeline associated devaluation process, although this process in domestic development time later than abroad, but due to the advanced nature of its technology, soon is accepted by the domestic market. Developed from the beginning of 1998, after just a few years of development and application, has gradually replaced the flange and welding of the two traditional ways of pipe connection. Not only the process is more mature, the market is generally recognized, but also a positive guidance of the national regulatory policies.
        Groove pipe fittings is very simple, do not need a special professional skills, ordinary workers after a simple training can mount. This is because the product has a large number of local precision process in factory way to dissolve waste in production. A pipes are associated and only a few minutes, maximum simplifies the field induction process difficulty, thrifty man hour, and also the stability of the engineering quality, improve the work efficiency. This is the general direction of the process of the device.
        Grooved pipe fittings, only in the surface of the connection pipe with a groove machine to squeeze out a groove, the groove pipe without damaging the structure of the inner wall, which is the unique process associated with the groove pipe fittings. If you use the traditional welding posts, many of the inner wall of the pipeline will be destroyed. And the standard rules on the galvanized pipe and plastic pipe, steel plastic composite pipe lining shall use of welding and flange connection, otherwise the demand for secondary disposal. The use of trench pipe fittings technology, the scene only needs cutting machine, groove machine and button bolt with the hand, construction organization. But the welding and flange connection, need complex equipment of power cable, cutting machine, welding machine and oxygen and acetylene gas, etc., it gives the construction organization and brings complexity and there is also the potential risks of the leakage and fire. Welding and cutting and welding slag, can not prevent the fall into the internal pipeline, used to produce pipes, valves and even equipment infarction and pollution tube water quality.
        Grooved tube is a new type of pipe fittings, which is also called the clamp connection, which has many advantages. Automatic take water fire extinguishing system design criteria is presented, the association of piping system should be the trench association or threaded connection, flange connection; system diameter equal to or greater than 100 mm of the pipeline should be segmented by flanges or trench related incident groove pipe connection technology is also called clamp associated technology, has become the liquid and gas pipeline associated devaluation process, although this process in domestic development time later than abroad, but due to the advanced nature of its technology, soon is accepted by the domestic market. Developed from the beginning of 1998 to now, after a few years of development and application, trench pipe has gradually replaced the flange and welding of the two traditional ways of pipe connection. Not only the process is more mature, the market is generally recognized, but also the positive guidance of the national regulations and policies.
