The comprehensive technical performance and economic indicator of PP-R are much better than galvanized pipe, UPVC pipe, polyethylene-aluminum compound pipe, PE-X (cross-linked polyethylene) and polybutylene pipe etc. For this reason PP-R is the leading products and widely used for feed-water piping in developed countries in Europe and America.
Nowadays PPR pipes win more attention and have been used all over the whole world more widely with its excellent sanitization performance, high heat resistance, compression resistance, corrosion resistance, pliability and seismic performance which make PP-R the real environmental friendly pipe
1)Light weight, convenient to transport and handle

- Q:Natural gas aluminum pipe, what fittings are best the used?
- Plastic aluminum pipe special pipe fittings.The aluminum plastic pipe is a composite pipe which is welded longitudinally by an intermediate aluminum pipe and is lined with polyethylene plastic inside and outside, and is bonded with hot melt adhesive between the layer and the layer. According to the use of classification, there are ordinary drinking water pipes, high temperature pipes, gas pipes.
- Q:When calculating the installation of water supply and drainage pipelines, are elbow and pipe fittings calculated separately?
- Water supply and drainage pipeline engineering, bends and fittings of the material shall be calculated separately, the installation fee is included in the pipeline installation quota, do not need to be calculated, such as industrial pipeline, the pipe installation fee plus
- Q:Regarding the connection of plastic pipes and inspection wells, is the flexible connection or rigid connection?
- Precast concrete manhole and pipeline reserved hole diameter should be greater than 0.2M diameter pipe or pipe fittings, before installing the reserved hole circumferential surface should be cut hair treatment; 5, check the bottom plate of basement with sand gravel cushion, pipe foundation layer flat connection.
- Q:PSP plastic steel composite pressure pipe has several ways of connecting
- The pipe wall is smooth, the fluid resistance is small, and the scale is not fouling. Under the same pipe diameter and pressure, the head loss is 30% lower than that of the metal pipe, and larger transmission flow can be obtainedConnection: the product adopts double hot melt connection, no leakage.
- Q:What is the plastic pipe joint of water supply pipes?
- You need to turn the elbow joint, need to connect a pipe to the hoop
- Q:What causes plastic pipes and fittings to burst easily?
- Pipe is widely used. Pipes are used in many industries.Different industries have different characteristics of the industry, and thus have different technical requirements.Pipe is a relatively mature product, each industry has the corresponding technical standards.Detect pipe material, according to the application of pipe industry, select the corresponding product standards, according to the industry needs to detect the corresponding technical indicators.
- Q:PE is the hot melt?
- 1. When using this method, the hot melt butt welding machine is adopted, and the main operation steps are as follows:After the butt welding machine has been debugged, put the pipe to be placed on the welding jig and clamp;The cleaning pipe end to be connected and connected with two end milling cutter alignment docking, the displacement is not greater than the pipe wall thickness of 10%:When the temperature of the heating plate reaches the set temperature, put it on the heating plate:After heating, take out the heating plate, quickly start the oil pump pressure, join the two pipe heating surface, and step up to the welding pressure, keep pressure and cool down:After cooling to the specified time, open the clamp and remove the pipe from the rack, observe the roll edge, determine the quality of the connection, and complete the connection.2. Check the quality of hot melt butt jointThe determination of the quality of hot melt butt welding is still mainly concerned with nondestructive appearance inspection of welding roll edges. Usually includes edge geometry and cutting edge visual inspection, the edge to behind the buckling to prove that connected with no lack of fusion check.Ultrasonic testing and X ray examination have been applied abroad.Destructive detection. Tensile test, bending test and tensile creep test are carried out at the interface respectively.3, hot melt docking notes:The procedures for the use of the docking machines and the matters needing attention shall be observed;Operators must wear gloves, wear overalls, do a good job of self-protection, to avoid electric shocks or burns;Heating the surface of the board, and the connecting ends should be kept clean:Docking pressure should be adjusted to the actual needs of the site:Polyethylene pipes shall not be heated by open flame;The welding interface to protect from sand and rain hit.
- Q:What are the characteristics, properties and uses of PVC plastics?
- PVC material, that is PVC, is one of the largest plastic products in the world. It is cheap and widely used. PVC resin is white or light yellow powder. Different additives can be added according to different uses, and polyvinyl chloride plastics can exhibit different physical and mechanical properties. A variety of hard, soft and transparent products can be made by adding proper amount of plasticizer in PVC resin.
- Q:How to connect the wire mesh, steel tape and plastic composite pipe?
- The connection of hole net, steel belt and polyethylene composite pipe can be made in two ways: fused pipe fittings and flange joint.
- Q:What is the PVC pipe fitting?
- PVC pipe (PVC-U pipe) rigid PVC pipe is made of PVC resin and stabilizer, lubricant and so on. It is extruded and formed by hot pressing method. It is the earliest plastic pipe to be developed and applied. PVC-U pipes are corrosion resistant, easy to adhere, low in price and hard in texture, but because of the exudation of PVC-U monomers and additives, they are only suitable for the feed water system with a temperature of not more than 45 DEG C. Plastic pipes are used to transport potable water, waste water, chemicals, heating and cooling fluids, foodstuffs, ultrapure liquids, slurries, gases, compressed air, and vacuum systems.
