Municipal units how to choose PE pipe, PE water supply pipe

How to choose a good pipeline is a very important thing. The quality of the pipe seriously affects the use of the pipe. Due to the improper selection of pipe materials, small editors have a large number of leaks in various explosive pipes. So, how do we choose the right PE class? Next, we will explain from the following six aspects. 1. appearance high-quality pe pipe: the inner and outer surfaces of the pipe are smooth and smooth without defects such as bubbles, dents, impurities, etc. Inferior products: the inner and outer surfaces of the pipe are not smooth, not bright, pitted, and the inner and outer surfaces have obvious depressions.. 2. milling strip high quality PE pipe: shiny, smooth, repeated folding is not easy to break. Inferior products: dark color, folding easy to break. The qualified welding port of 3. welding port shall have smooth and symmetrical flanging along the whole circumference of the pipe, and the minimum depth of flanging shall not be lower than the surface of the pipe; the misalignment of any place on the outer circumference of the weld adjacent to the flanging on both sides of the weld shall not exceed 10% of the wall thickness of the pipe; high-quality PE pipe: flanging is smooth and flat. After the joint pressure, the flanging can be longer. Inferior products: flanging after the surface produces a large number of pores. The flanging is short after the joint pressure. 4. rely on the smell of high-quality PE pipe inferior PE pipe construction process, heating and melting after the PE pipe has a slight plastic fragrance, the product after cooling no smell. Inferior PE pipe: a pungent smell. The elongation at break of the 5. refers to the ratio of the length of the sample to the original length at break, and the elongation at break is about high, indicating that the better the flexible type of PE pipe, the better the performance. Good PE pipe: stretched to 3.5 times without breaking. Inferior products: elongated easy to break, poor toughness. 6. Oxidation induction time Oxidation induction time is the time when the sample begins to undergo autocatalytic oxidation reaction under high temperature oxygen conditions, and is an indicator for evaluating the thermal degradation resistance of materials during molding, processing, storage, welding and use. The longer the oxidation induction time, the better the aging resistance and the better the performance of the product. yushun pipeline, is a professional pe pipe factory in shandong province, specializing in the production and supply of: pe water supply pipe, pe threading pipe, pe water supply pipe, pe drainage pipe, siphon drainage pipe. Domestic large PE pipe, PE water supply pipe manufacturer → Shandong Yushun Pipeline Engineering Co., Ltd.
