Performance Advantage of HDPE Pipe Fitting

A good pipeline should not only have good economy, but also have a series of advantages, material impact resistance, cracking resistance, aging resistance and corrosion resistance. Compared with traditional pipelines, HDPE pipeline system has the following series of advantages:

⑴Reliable connection: the PE Pipe Fitting Socket Fusion system is connected by electric thermal melting mode, and the joint strength is higher than that of the pipe body.

⑵Good low temperature impact resistance: for polyethylene, the low temperature brittlement temperature is very low, and it can be used safely in the temperature range of-60-60℃. In winter construction, because the material impact resistance is good, the pipe brittle crack will not occur.

⑶Good stress cracking resistance: HDPE has low gap sensitivity, high shear strength and excellent scratch resistance, environmental stress cracking resistance is also very outstanding.

⑷Good chemical corrosion resistance: the HDPE Pipe Fitting can withstand the corrosion of a variety of chemical media, and the chemicals existing in the soil will not cause any degradation of the pipeline. PE Fitting Gas is an electrical insulator that does not cause decay, rust, or electrochemical corrosion; and it also does not promote algae, bacteria, or fungi.

⑸Aging resistance, long service life: a polyethylene pipe containing 2-2.5% evenly distributed carbon black can be stored outdoors or used outdoors for 50 years without damage due to ultraviolet radiation.

⑹Good wear resistance: the wear resistance comparison test of HDPE Pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. In the field of mud transportation, HDPE Pipe Fittings have better wear resistance compared to steel pipes, which means that HDPE Fittings have longer service life and better economy.

⑺Good flexibility: the flexibility of the PE Pipe makes it easy to bend, engineering can bypass obstacles by changing the direction of the pipeline, in many cases, the flexibility of the pipeline can reduce the amount of pipe fittings and reduce the installation costs.

⑻Small flow resistance: PE Pipe has smooth inner surface with Manning coefficient of 0.009. The smooth performance and non-adhesion characteristics ensure that the PE Fitting has a higher transmission capacity than the traditional pipe, but also reduce the pressure loss and water transmission energy consumption of the pipeline.

⑼Easy handling: HDPE pipe is lighter than concrete pipe, galvanized pipe and steel pipe, it is easy to carry and install, lower manpower and equipment requirements, which means that the installation cost of the project is greatly reduced.

⑽A variety of new construction methods: HDPE pipeline has a variety of construction technology, in addition to the traditional way of excavation construction, can also use a variety of new trenchless technology such as pipe jacking, directional drilling, lining, crack pipe construction, for some places do not allow excavation, is the only choice, so HDPE pipeline is more widely used.
