What material is HDPE pipe connection made of?

HDPE (high-density polyethylene) is a highly crystalline, non-polar thermoplastic resin. It has high hardness and tensile strength, but is prone to cracking. Nowadays, PE and PVC-U are mostly used in water conservancy. Use pipe clamps when connecting

HDPE Performance Characteristics A good pipe should not only have good economy, but also have a series of advantages such as stable and reliable interfaces, material resistance to impact, crack resistance, aging resistance, corrosion resistance, etc. Compared with traditional pipes, HDPE pipeline systems have the following advantages: ⑴Reliable connection: The polyethylene pipe systems are connected by electric heat fusion, and the strength of the joints is higher than the strength of the pipe body. ⑵Good low temperature impact resistance: Polyethylene has an extremely low low-temperature embrittlement temperature and can be used safely within the temperature range of -60-60°C. During winter construction, pipe brittleness will not occur due to the good impact resistance of the material. ⑶Good 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. ⑷Good chemical resistance: HDPE pipes can withstand corrosion from a variety of chemical media, and chemicals present in the soil will not cause any degradation to the pipes. Polyethylene is an electrical insulator and therefore will not rot, rust or electrochemical corrosion ； Additionally it does not promote algae, bacteria or fungal growth. ⑸Aging resistant, long service life: Polyethylene pipes containing 2-2.5% evenly distributed carbon black can be stored outdoors or used for 50 years without being damaged by UV radiation. ⑹Good wear resistance: Comparative tests on the wear resistance of HDPE pipes and steel pipes show that the wear resistance of HDPE pipes is 4 times that of steel pipes. In the field of slurry transportation, HDPE pipes have better wear resistance than steel pipes, which means HDPE pipes have longer service life and better economy. ⑺Good flexibility: The flexibility of HDPE pipes makes them easy to bend. In engineering, obstacles can be bypassed by changing the direction of the pipes. In many cases, the flexibility of pipes can reduce the amount of pipe fittings and installation costs. ⑻Small flow resistance: HDPE pipe has a smooth inner surface and its Manning coefficient is 0.009. The smooth performance and non-adhesive characteristics ensure that HDPE pipes have higher transportation capacity than traditional pipes, while also reducing the pressure loss and water transportation energy consumption of the pipeline. ⑼Easy to transport: HDPE pipes are lighter than concrete pipes, galvanized pipes and steel pipes. They are easier to transport and install. Lower manpower and equipment requirements mean that the installation cost of the project is reduced. * * reduce. ⑽A variety of new construction methods: HDPE pipes have a variety of construction technologies. In addition to traditional excavation methods, HDPE pipes can also be constructed using a variety of new trenchless technologies such as pipe jacking, directional drilling, lining pipes, cracked pipes, etc. This is the only option for some places where excavation is not allowed, so HDPE pipes have a wider application field. Connection method: steel flange connection, connection with concrete inspection well, electric fusion connection, etc.

HDPE has special pipe fittings, which are generally connected by hot melting. At the same time, the hot melting temperature needs to be controlled, usually around 250 to 300 degrees. Some HDPE pipes have steel mesh inside, or thin steel plates with holes as skeletons. This kind of pipe fittings are also hot melted, but more convenient than simple HDPE pipes. There are electrical connections on the pipe fittings. It only takes a few minutes to use a welder according to the parameters provided by the manufacturer. The manual requirements for workers are much lower! When connecting HDPE to pipes made of other materials, just use steel flanges! :loveliness:

PE or PVC-U pipe.
