Now HDPE pipes are also one of the HDPE pipes in agricultural water supply, fire hoses in cities, and so on. Due to its unique corrosion resistance, long use time and cold resistance, the HDPE tube is popular among many companies. There are many HDPE varieties on the market. Some people don't know HDPE Water Supply Pipe and HDPE Drainage Pipe. Let's talk about the difference between the two today.
HDPE Water Supply Pipe must withstand a certain pressure. Generally, PE resin with high molecular weight and good mechanical properties is selected. For example, HDPE resin has low tensile strength, poor pressure resistance, poor rigidity, poor dimensional stability during molding, and difficult connection. Suitable as a material for the water supply pressure pipe. However, due to its high health index, HDPE resin has become a common material for the production of drinking water pipes. The HDPE resin has a small melt viscosity, good fluidity, and easy processing, and thus a wide selection range of its melt index, usually between 0.3 and 3 g/10 min.
HDPE Drainage Pipe is actually a high-density polyethylene double-wall corrugated pipe. Its main feature is that its external structure is especially a ring-shaped corrugated structure. In fact, this design is useful, which greatly increases the pipe. Ring stiffness to increase the resistance of the pipe to soil loading. This is an advantage that no pipe can replace, and HDPE pipe is cheaper. This is also a price advantage. The pvc drain pipe is mainly because it is not sensitive to the outside temperature, so there is little water pipe bursting phenomenon and its heat preservation is also good, so it is convenient to not generate condensed water. As for which one to choose, I feel that each has its own advantages depending on the situation.
