product description

HDPE gas pipe is made of special polyethylene as a raw material and extruded by plastic extruder for plastic pipe. Performance characteristics

★Reliable connection: The polyethylene pipe system is connected by electric hot melt or hot melt butt joint, and the strength of the joint is higher than the strength of the pipe body.

★ Low temperature impact resistance: Polyethylene has a very low temperature embrittlement temperature and can be safely used in the temperature range of -60-60 °C. In winter construction, due to the good impact resistance of the material, the tube will not be brittle.

★ Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and environmental stress cracking resistance is also very prominent, greatly reducing the risk of malignant accidents caused by pipe cracking.

★Good chemical resistance: PE is an inert material. It can resist the erosion of many chemical substances except a small amount of oxidant. The chemical substances in the soil will not cause any degradation to the pipeline. Polyethylene is an electrical insulator and therefore does not rot, rust or electrochemically corrode.

★Aging resistance, long service life: Polyethylene pipes with 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without being damaged by UV radiation.

★ Good wear resistance: The comparison of wear resistance of HDPE pipe and steel pipe shows that the wear resistance of HDPE pipe is 4 times that of steel pipe. HDPE pipes have better wear resistance, which means HDPE pipes have a longer service life and better economy.

★Flexible: HDPE pipe has high toughness and elongation at break of more than 500%. It is easy to bend. In engineering, the obstacle can be bypassed by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the amount of pipe fittings. Reduce installation costs.

★Low flow resistance: HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. The smooth performance and non-adhesive properties ensure that the HDPE pipe has a higher conveying capacity than conventional pipes, while also reducing the pressure loss and gas transmission energy consumption of the pipe.

★ Convenient handling: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easy to handle and install. The lower manpower and equipment requirements mean that the installation cost of the project is greatly reduced.

★ A variety of new construction methods: HDPE pipelines have a variety of construction techniques. In addition to traditional excavation methods, a variety of new non-excavation techniques such as pipe jacking and directional drilling can be used for construction. This is the only option for sites that do not allow for excavation, so HDPE piping is used in a wider range of applications.
