PE Lay Flat Hose Variability Range
PE Lay Flat Hose Variability range
PE flat hose has stretchability, but the PE flat hose stretch on the PE flat hose What are the benefits? So here's a brief talk about the benefits of stretch.
The macromolecule polymer has the widest range of mechanical properties in all known materials because of its high molecular weight composition due to the long chain molecules and the molecular motion with significant relaxation properties. Such as high polymer material has a very high elongation, the general elongation of PE elongation of 90% to 950%, through a special production process, part of the elongation of materials can be above 1000%, while the general high Material elongation at break is also more than 50% to 100%. Generally, the tensile properties of the material are required to have a heat-shrinkable film and a stretch film. PE flat hose at the time of installation, most buried in the ground, buried in the ground how to ensure that PE flat hose can work properly is a problem, it depends on the PE flat hose buried application technology, the following together take a look.
First, the primary skills function
PE flat hose with BP, the Nordic chemical PE material, the introduction of the international advanced level of the extrusion of the production line, the use of spray cooling method to cool the pipe around the average, the wiring method with the international advanced degree of advanced post-wiring skills , Water pipe, pipe fittings have Φ20 ~ 630mm of various specifications, all kinds of pressure grade, complete specifications, supporting intact.
Second, the combination of limitations and the use of prerequisites
Mainly for the water supply, drainage and other transportation piping system, alternative metal pipe and other poor corrosion resistance of the pipeline, in the -60 ℃ ~ 40 ℃ temperature limit within the life of up to 50 years. PE flat hose must withstand a certain pressure, usually to use a large molecular weight, better mechanical properties of PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficulty in connection, and is not suitable as a material for water supply pressure pipes. However, due to its higher health indicators, LDPE, especially LLDPE resin has become a common material for the production of drinking water pipes. PE pipe is currently China's municipal pipe market, plastic pipe is steadily developing, PE pipe, PP-R pipe, UPVC pipe have a place, which PE pipe strong momentum of the most impressive. PE pipe use a wide range of areas. Which gives the water pipe and gas pipe is its two largest application market.
PE resin: is made of monomer ethylene polymerization, due to the polymerization pressure, temperature and other polymerization conditions are different, can be obtained different density of resin, and thus high density polyethylene, medium density polyethylene and low density poly Ethylene In the processing of different types of PE pipe, according to its different application conditions, the choice of different resin grades, while the requirements of the extruder and mold are also different.
PE flat hose: water supply PE pipe is the traditional steel pipe, PVC drinking water pipe replacement products. Water pipes must withstand a certain pressure, usually to use a large molecular weight, mechanical properties of better PE resin, such as HDPE resin. LDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficulty in connection, and is not suitable as a material for water supply pressure pipes. However, due to its higher health indicators, LDPE, especially LLDPE resin has become a common material for the production of drinking water pipes.
