Plastic composite pipe specifications

As the construction is simple, and there is no contradiction between the impact and other projects, shorten the construction period, the construction cost savings of 60% than copper, with excellent economy. • PP-R pipes and fittings of use 1. Residential: cold houses, villas, hot water and heating use. 2. Public buildings: office buildings, markets, theaters, barracks and other public buildings and water radiant floor heating.
Transport installations: piping airport, bus terminal, car parks, garages, motorway. 4. Flora and fauna by: the zoo, botanical gardens, greenhouses, farm pipe. 5. Sports facilities with: cold swimming pool, sauna, and hot water pipes. 6. Sanitary: water supply, piping hot water pipe. 7. Other: Industrial pipes. What is a composite pipe? Composite pipe is a metal pipe as the basis, inside and outside the welding of polyethylene, cross-linked polyethylene and other non-metallic materials forming, with the advantages of metal pipes and nonmetallic tubing. There are currently on the market the more common plastic composite pipe, copper plastic composite pipe, plastic composite pipe, plastic composite pipe, steel skeleton of PE pipe. The following will be described only several common. ` plastic composite pipe. Plastic composite pipe is the middle layer of welded aluminum, both inside and outside a layer of polyethylene, bonded together by the glue layer of five pipes, polyethylene plastic pipe has the advantage of good corrosion resistance and high pressure metal tube, polyethylene plastic composite pipe according to different materials into two categories: for hot water in the crosslinked polyethylene plastic composite pipe and is suitable for cold water high-density polyethylene plastic composite pipe.
Plastic composite pipe specifications for Φ14 ~ Φ 32, using clamping copper fittings link, mainly used for building water distribution manifold and heater tubes, more expensive. a plastic composite pipe. Plastic composite pipe is made of galvanized pipe wall thickness means certain UPVC plastic made, which also has the advantages of steel and plastic tubing. Pipe specifications for Φ15 -Φ 150. Copper fittings threaded coupling, using less water temperature is 50 , more buildings to be used as cooling water, more expensive. b steel skeleton PE pipe. PE pipe steel skeleton is high quality low carbon steel wire as reinforcing phase, high-density polyethylene as the matrix, through a network of steel wire and plastic extrusion filling simultaneously, on the production line continuous tension membrane forming a new double-sided anti-corrosion pressure pipeline. Diameter of Φ 50 ~ Φ 500, flange coupling, mainly used for municipal, chemical and oil pipeline network, more expensive. c plastic pipe. Plastic pipe in the pipe wall is thawed to a thickness of 0.5 ~ 1.0mm of polyethylene (PE) resin, ethylene - acrylic acid copolymer (EAA), epoxy (EP) powder, non-toxic polypropylene (PP) or without steel-plastic composite pipe toxic polyvinyl chloride (PVC) and other organic matter constituted, it not only has high strength steel pipe, easy connection, impact resistance, water, etc., but also to overcome the corrosive water pipe, pollution, fouling and plastic pipe strength is not high, defects and poor fire performance, the design life of up to 50 years. The main disadvantage is that can not be bent, thermal processing and cutting operations such as welding installation, the cut surfaces manufacturer with some non-toxic room temperature curing adhesive brushing. The main specifications are Φ15 -Φ 100. What is hard PVC UPVC pipe? Hard PVC pipe is PVC resin at a certain temperature to add lead, tin, radium, mercury and other metal compounds as a stabilizer melt together, pipes used for the first heavy metal precipitation. The Hague, Netherlands Waterworks for A, B, C, D several manufacturers of UPVC pipe lead for an hour dialysis experiment conditions:Steel tube length 4m, a flow rate of 0.67m / h, it can be seen from the experimental results, Lead precipitation amount over time, the concentration will be reduced, but the water temperature and pH have a significant impact on the amount of lead in dialysis, the pH is neutral, the minimum amount of dialysis; pH value decreases or increases will increase the pipe The amount of lead dialysis; the higher the temperature, the longer the water pipe network in residence time, the greater the amount of lead in dialysis. Construction UPVC pipe, pipe diameter from the Φ20 to Φ315, working pressure of 1.0 ~ 2.5MPa.
