Lined pipe trench has an outstanding resistance to corrosion. Incorporated in the plastic-lined pipe trench wall polyethylene, polypropylene, polyvinyl chloride and other clean secure, stable plastic material does not contain toxic substances. After the combination of plastic pipe wall, no rust, no scaling, wall lubrication, and aging. In the absence of external corrosion, the life lined pipe trench can reach life of the building. With the support used may inner malleable iron pipe fittings look choose an injection molding technology, the lining of a protective layer of plastic lined pipe trench production, after the tube and pipe adapter, make sure the pipe from corrosion, now it has as a water pipe to transport water resources. Grooved fittings include two categories products: ① of the connecting pipe sealing rigid joints, flexible couplings, grooved mechanical tee and flange; ② role in the transition from the tube connections are elbows, tees, crosses, reducers, blind panels. Groove Tube diameter pipe What characteristic diameter pipe diameter pipe materials including stainless steel, alloy steel, carbon steel size head diameter pipe diameter pipe 20 steel q234q345, the product has a beautiful appearance, smooth surface silver-lined ditch Manufacturers, acid, anti-corrosion, strong performance advantage texture trough tube. For water, oil, gas media. And some corrosive liquids, petroleum, chemical, water, electricity, boiler, shipbuilding and other industries. Lined trench tube manufacturers, Chuanhai machinery (online consultation), Zigong lined pipe trench is provided by Weifang Chuanhai Machinery Co. Weifang Chuanhai Machinery Co., Ltd.
