Qian Xiang Yu machinery by the groove pipe connection CNN system, provide a full set of technical support, combined with the actual situation in China, using Neiyinwailian, developed the vacuum casting and lost foam casting two international advanced casting technique combined with vacuum expendable pattern casting process production equipment groove tube, the material is ductile iron QT450-10.
        The groove tube is also called the clamp connection. The main advantages are as follows:
        A fast, economic, the resettlement resettlement without extra skills, low repair rate, so it can reduce the work of comprehensive settlement 30-50%.
        Two, Christmas with groove type clamp approached and fittings place to start, simply mechanical assembly, without welding, no open flame, so that there is no welding slag turbid pipeline, to ensure safe site, start the fire ban conditions, especially as appropriate.
        Three, light clamp contact light weight, the number of bolts is small, easy to place, do not have to be extra skills.
        Fourth, reliable scientific and reasonable organization plotting, strange c type rubber sealing ring, to realize the triple seal, guarantee the sealed connection reliability.
        Five, occupied space minor groove type clamp contact link space accounted for about 70%, and due to the less number of fastening bolts and no object, especially practical conditions for the start of the space is narrow.
        Six, quick to take the groove clamp contact and the corresponding pipe fittings, start to do not need to be welded, do not have to two galvanized, two placement. Increase the placement rate.
        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.
