Advantage of HDPE pipe:
Reliable connection: the polyethylene pipe system is connected by electric hot melt method, 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, no brittle cracking will occur.
Good resistance to stress cracking: HDPE has low notch sensitivity, high shear strength and excellent scratch resistance, and environmental stress cracking resistance is also outstanding.
Good chemical resistance: HDPE pipes are resistant to corrosion by a variety of chemical media, and chemicals present in the soil do not cause any degradation to the pipe. Polyethylene is an electrical insulator, so it does not rot, rust or electrochemically corrode; it also does not promote the growth of algae, bacteria or fungi
Anti-aging, long service life: Polyethylene pipes with 2-2.5% evenly distributed carbon black can be stored or used outdoors for 50 years without damage from 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. In the field of mud transport, HDPE pipes have better wear resistance than steel pipes, which means HDPE pipes have a longer service life and better economy.
Good flexibility: The flexibility of the HDPE pipe makes it easy to bend, and the engineering can bypass the obstacle by changing the direction of the pipe. In many cases, the flexibility of the pipe can reduce the pipe usage and reduce the installation cost.
Low water flow resistance: The HDPE pipe has a smooth inner surface with a Manning coefficient of 0.009. Smooth performance and non-adhesive properties ensure that HDPE pipes have higher conveying capacity than conventional pipes, while also reducing pipe pressure loss and water delivery energy consumption.
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 the traditional excavation methods, a variety of new non-excavation techniques such as pipe jacking, directional drilling, liners, cracking Construction by pipe, etc. This is the only option for some places that are not allowed to be excavated.
Brief introduction of PE pipe production process:
The first step, raw material compounding and drying: PE pellets and water supply pipes are purchased from PE pellets, first mixed with the added masterbatch and antistatic masterbatch (gas tube) in the mixing mixer. After uniformity, the uniformly mixed material is pumped into a storage tank having a heating and drying function by a suction machine.
The second step, the plasticizer extrusion molding of the extruder: the extruder screw barrel and the molding die are electrically heated by the externally coated heating ring, and the working temperature is 160-220 °C. The material enters the extruder barrel from the storage hopper, and is conveyed, metered, plasticized, and compressed into the molding die under the conveying and shearing of the spiral rib. A small amount of mixed color strands are heated and plasticized by a small screw extruder to enter from the side of the mold. The two materials are mixed and extruded through a die.
The third step, vacuum setting cooling: the formed material passes through the sizing sleeve into the vacuum cooling box for shaping and pre-cooling, and then after two stages of cooling to cool to normal temperature and complete the shaping process.
The fourth step, printing, drawing, cutting, turning and winding: the shaped pipe is printed, and the length is measured under the traction, and the cutting machine enters the turning frame or the winding machine (for the pipe below DN50), and Cut to the set length.
The fifth step is to inspect the qualified products into the warehouse: the cut products are inspected and the qualified products enter the warehouse. The non-conforming product and the waste scrap produced during the production process are crushed and returned to the production system for reuse.
