The distinguishing method of PVC pipe ,The difference analysis of pipe PVC and PVC-U

How to distinguish PVC pipes: Plastic pipes are currently the most widely used pipe products in the construction industry, and they are also widely used in other industries. Nowadays, the most commonly used plastic pipe products are PVC pipes. This type of pipe has good performances such as compression and corrosion resistance, and it plays a very important role in construction.

The Advantage of PE Pipes

Good toughness and flexibility. PE pipe is a high-toughness pipe with a breaking elongation of more than 500%. It has strong adaptability to uneven settlement and dislocation of the pipe foundation and good shock resistance. In addition, PE pipe can be coiled (especially for small pipe diameters) so can reducing pipe fittings use. The direction of the PE pipe is easy to change according to the requirements of the construction method. During construction, obstacles can be bypassed within the allowable bending radius of the pipe to reduce the difficulty of construction.

Composition of PE Pipe Production Line

The PE pipe production line includes: feeding system, single screw extruder, PE pipe special mold, calibrator, cooling system, tractor, coiler, control system. The extruder is one of the important core components of the pipe extrusion line. In the design of a single screw extruder, how to achieve high-speed extrusion of high-quality pipes at low processing temperatures is a key technology. In the screw design, the BM structure and the barrier structure are combined, and a special mixing section is added, which not only ensures the plasticizing effect of the tube blank, but also the material is in each area on the entire screw, and the melt pressure is lower. , The pressure is evenly distributed, and the shearing action is strictly controlled to obtain the ideal material temperature.

Three prevention measures for PPR pipe construction

To make the PP-R pipe piping system, whether it is a gas pipeline or a water supply pipeline, can work normally for a longer period of time, in addition to strengthening maintenance and management in the mouth, three prevention measures need to be taken during the design and construction process, namely, antifreeze, Anti-corrosion and anti-noise measures.

Usage of PE pipe

Among all engineering plastics, HDPE has the highest wear resistance and is the most noticeable. The higher the molecular weight, the more wear-resistant the material is, even exceeding many metal materials (such as carbon steel, stainless steel, bronze, etc.). Under the conditions of strong corrosion and high wear, the service life is 4-6 times that of steel pipe and 9 times that of ordinary polyethylene; And the conveying efficiency is improved by 20%. The flame retardant and antistatic properties are good and meet the standard requirements. The downhole service life is over 20 years, with remarkable economic benefits, impact resistance, wear resistance and double resistance.

The difference between PPR pipe and PE pipe

In terms of drinking water, PE is generally used as cold water pipe; PP-R (special hot water material) can be used as hot water pipe; PP-R (cold water material) can also be used as cold water pipe; If it is to be hot water pipe, of course it is PP -R is good; (If it is a drinking water pipe in a home decoration, then there is no need to distinguish, basically PP-R is used more than PE) If it is a cold water pipe, you can refer to the following differences:
