HDPE Pipe Fitting System,Pipe and fittings shall be manufactured from virgin HDPE (High Density Polyethylene) compounds.n⑴Reliable connection: Polyethylene pipe systems are connected by electric heat fusion, and the strength of the joints is higher than the strength of the pipe itself.n⑵Good low-temperature impact resistance: Polyethylene has an extremely low low-temperature embrittlement temperature and can be used safely in the temperature range of -60-60°C. During winter construction, pipe brittleness will not occur due to the good impact resistance of the material.n⑶Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and its environmental stress cracking resistance is also very outstanding.

HDPE Pipe Fitting System,Pipe and fittings shall be manufactured from virgin HDPE (High Density Polyethylene) compounds.nHDPE, also known as high-density polyethylene, is a thermoplastic resin with relatively high crystallinity.nHigh-density polyethylene is a white powder or granular product with a crystallinity of 80% to 90%, a softening point of 125 to 135°C, and a service temperature of up to 100°C. It is insoluble in any organic solvent at room temperature and is acid and alkali resistant. and corrosion from various salts; the film has low permeability to water vapor and air, low water absorption; and poor aging resistance. However, high-density polyethylene films have a low thermal deformation temperature under stress, so care should be taken during application.

HDPE Pipe Fitting System,Pipe and fittings shall be manufactured from virgin HDPE (High Density Polyethylene) compounds.nchemical propertiesnPolyethylene is resistant to a variety of organic solvents and acid and alkali corrosion, but is not resistant to oxidizing acids such as nitric acid. Polyethylene will be oxidized in an oxidizing environment.nphysical propertiesnPolyethylene can be considered transparent in its film state, but when it exists in a block form, it is opaque due to strong light scattering due to the presence of a large number of crystals inside it. The degree of crystallization of polyethylene is affected by the number of branches. The more branches, the more difficult it is to crystallize. The crystal melting temperature of polyethylene is also affected by the number of branches, ranging from 90 degrees Celsius to 130 degrees Celsius. The more branches, the lower the melting temperature. Polyethylene single crystals can usually be prepared by dissolving high-density polyethylene in xylene at temperatures above 130 degrees Celsius.n

HDPE Pipe Fitting System,Pipe and fittings shall be manufactured from virgin HDPE (High Density Polyethylene) compounds.nHDPE pipes must withstand a certain amount of pressure, and PE resins with large molecular weight and good mechanical properties, such as HDPE resin, are usually used. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding and processing, and is difficult to connect, making it unsuitable as a material for water supply pressure pipes. However, due to its high hygienic indicators, LDPE, especially LLDPE resin, has become a commonly used material for the production of drinking water pipes. LDPE and LLDPE resins have small melt viscosity, good fluidity and easy processing, so the selection range of their melt index is also wide, usually MI is between 0.3-3g/10min.

HDPE Pipe Fitting System,Pipe and fittings shall be manufactured from virgin HDPE (High Density Polyethylene) compounds.nAdvantagen1. PVC pipes have good tensile and compressive strength, but their flexibility is not as good as other plastic pipes.n2. The pipe wall of PVC pipe is very smooth, so the resistance of water flow is very small. Its water transport capacity is 20% higher than that of cast iron pipes of the same diameter, and the water transport effect is very high.n3. Moreover, PVC pipes are also very corrosion-resistant and chemical-resistant. They have good acid resistance, alkali resistance, corrosion resistance, are not affected by moisture and soil pH, and have a long service life.n4. PVC pipes also have good water tightness. This type of pipe can maintain good water tightness regardless of whether it is connected by bonding or rubber rings.n5. PVC pipe has good stretchability and thermal stability, can be adapted to different environments, and has a wide range of uses.n6. As mentioned earlier, PVC pipes have good hardness, so they are used as drainage pipes to prevent insect and ant erosion and have a longer service life.

HDPE Pipe Fitting System,Pipe and fittings shall be manufactured from virgin HDPE (High Density Polyethylene) compounds.nHDPE water supply pipes are widely used, mainly because they have advantages that other pipes cannot match:n1. It is easy to form a closed anti-seepage system by butt welding and electrofusion welding. When laying along the trench, the amount of earthwork excavated in the trench can be reduced and the amount of accessories used can be reduced.n2. Light weight and easy to install and handle;n3. Strong wear resistance and excellent hydraulic performance, no outer layer protection is needed in buried pipelines. It is suitable for earthquakes and soil settlement areas in mining areas, and can also be laid at the bottom of rivers by the sinking method.

HDPE Pipe Fitting System,Pipe and fittings shall be manufactured from virgin HDPE (High Density Polyethylene) compounds.nHDPE pipe is a thermoplastic polyolefin pipe produced by ethylene copolymerization. Its raw material HDPE is a highly crystalline, non-polar thermoplastic resin. And it must withstand a certain amount of pressure. PE resin with large molecular weight and good mechanical properties is usually selected. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding and processing, and difficult connection, so it is not suitable as a Materials for water supply pressure pipes.
