Features: 1, high mechanical strength: excellent physical properties PVC-U pipes, water pressure resistance strength, resistance to external pressure strength, good impact strength etc., applicable to a variety of conditions of the plumbing. 2, excellent chemical resistance: PVC-U pipe has excellent resistance to acid, alkali, corrosion resistance, no rust, to the chemical industry very appropriate. 3, fluid resistance: PVC-U pipe wall smooth, fluid resistance is small, the roughness coefficient is only 0.009, lower than other pipe in the same flow, pvc drainage pipes, pipe diameter can be reduced; at the same diameter case than the cement pipe, cast iron pipe flow increased by 30%. 4, long life, anti-aging: Pipes good weather resistance, anti-aging, for a variety of working conditions under the drain pipe works, long life, under normal working conditions can be 50 years. 5, light weight, convenient transportation and handling: PVC-U pipes light weight, pvc drainage, transportation is convenient, easy to install, can significantly speed up the construction schedule, saving construction costs. 6, aesthetic appearance, simple construction, lower construction cost: quickly and easily engage construction of PVC-U pipes, pvc drains 110, low construction cost of the project so than other materials product cost savings of more than 30%. Pipeline Features 1, health reliable pipes and fittings are non-toxic, tasteless, corrosion-resistant material that can make long-term water quality remains unchanged, will not impact on health. 2, soft and tough cost-pipe can be easily bent, in many projects can significantly reduce the use of accessories. 3, wear little roll supply pipe can be cut on-site measuring tape, wear minimal. 4, low thermal conductivity improves the efficiency of water delivery, and avoid accidental burns. 5, no closure pipe fittings and pipe inner diameter consistent, maintaining the flow constant. 6, after receiving a mild shock impact recoverable prototype, pvc drainage pipe wall thickness, to avoid accidental impact damage, to overcome the disadvantages of metal pipes and composite pipes. 7, excellent flow properties, to ensure reliable of its thin wall, most of the plastic pipe with the same diameter with a wall thickness of minimum flow relatively greatest feature. pvc drains 110 | pvc drainage pipes | source through resistance provided by the Henan source resistance Technologies Limited.
