White PE pipe of LDPE pipe

 　What is the white PE pipe? When the customer re-constructs or purchases, they will encounter the design institute or the industry mainly designated white PE pipes. So what is the white PE pipe? Here we give an introduction to several varieties of white PE pipes.

　　One: LDPE tube

　　LDPE pipes are actually low-density PE pipes. PE itself is divided into high-density polyethylene (HDPE) and low-density polyethylene (LDPE). The color of LDPE pipes is snow-white, usually coiled pipes. However, the amount of straight pipes is gradually increasing. , LDPE pipe is mainly used for threading. It is characterized by being transparent and relatively hard. The defect is that it cannot be pulled up. It is not suitable for trenchless pipe jacking.

　　Two: HDPE pipe

　　HDPE pipes are high-density polyethylene pipes. The HDPE material itself is white. The main reason why the PE pipes we see on the market are black is that the black master is added. From the perspective of the use of pipes, the addition of After the black mother, the pipe is not clear, so that the possibility of breeding harmful bacteria is reduced. The pipe made of pure new material HDPE material is white without adding black masterbatch. This kind of pipe has the advantages of two layers of stretchability and ring stiffness, and the sanitary index is also passed, but the cost is high, so the general market will not choose it. , Unless there are special requirements, of course, it is even more unlikely to be used for power threading pipes.

　　Three: Hybrid PE pipe

　　Due to the needs of customers or owners, it is necessary that the color of the PE pipe needs to be white, so it is possible to mix LDPE and HDPE materials in the production, and perhaps also use high-quality HDPE recycled materials. Many customers here think that recycled materials are not good materials. In fact, this is a very wrong concept. Some functional indicators of the application of recycled materials in foreign countries are better than brand-new materials. The white PE pipe made with the mixed formula has good functions, and the cost is relatively low compared with pure HDPE material. It is suitable for market application and is the most mainstream non-excavation power PE pipe.
