How to identify the quality of HDPE trenchless pipe?

When buying HDPE trenchless pipe, quality comes first. Some people look at the color of the PE pipe to distinguish the quality of the pipe. In fact, regarding the color of PE pipes, some people say that red is good, some people say that white is good, and some people say that black is authentic. In fact, the color has nothing to do with the quality of the PE pipe.
Color problem of HDPE trenchless pipe
Generally black, other colors can be negotiated by both parties. Regardless of black, white or red, tubes of different colors are the result of adding different color masterbatches, regardless of quality. The purpose of this is to prevent bacteria from growing in the test tube due to the transmission of light.
Sometimes in order to meet market demand, it is also a common practice to change the color to orange, red and other personalized colors to highlight individuality and increase selling points.
The quality of HDPE trenchless pipe mainly depends on the thickness of the pipe wall?
In fact, the quality of the pipe involves many aspects, and the wall thickness is only one of them. The temperature and pressure resistance of the pipeline depends partly on the purity of the raw material and partly on the adaptability of the wall thickness to temperature and pressure. Not that thicker is better, because thicker pipes have less runoff. The most important thing is the uniformity of wall thickness. Without adequate in-line control measures for pipe production, it is difficult to ensure uniform thickness.
In use, if there is a problem with the PE pipe, the impact will be very serious. Often the burst or blockage of the pipe will cause dozens, hundreds of times or even immeasurable consequences to the price of the water pipe itself.
