Lined pipe trench on the basis of a pipe trench is lined on the inside, this is a long time to be able to use plastic-lined pipe trench, lined trench tube manufacturers, can greatly reduce the risk of maintenance and replacement . Development of technology of a pipe lined with an interior of the pipe when the pipe trench lined Jinhua, allowing the use of the laying of the pipeline longer, consider lined pipe trench is formed with a groove so device is also more convenient, once by virtue of their own strengths into a high-volume commodity on the market, grooved border element with a high-strength ductile elongation. Municipal water supply pipes, the construction of water supply and drainage and agricultural use of the pipeline is still the primary category of plastic pipes, the use of the share of gas, heating, communications, silver plastic-lined pipe trench, as well as chemical, electric power, and other industrial areas continues to improve, lining plastic pipe fittings in trenchless category of use is also expanding. Groove Tube is referred to three, Stone, elbow, clamps and other fittings as classification lot of time in convergence, since each type of pipe has different needs. It said the first three-way convergence of mechanical, when convergence should look tee and hole gap, even after the various parts can be tightened. Mechanical tee opening gap not less than 500 mm, not less than 1000 mm mechanical four-Gong Li, at the time of convergence, which branch pipe diameter should be satisfied with the relevant regulations. Before convergence, should be sampled to view about 20%, respectively, view at least five directions, usually carefully observed surface and measuring tape data scale. Lined groove tube _ _ Jinhua plastic-lined pipe trench Chuanhai machinery provided by Chuanhai Machinery Co., Ltd. Weifang. Weifang Chuanhai Machinery Co., Ltd.
