I believe that some netizens have found a phenomenon when using polyethylene pipes - linear cracking.
A good polyethylene pipe has quite excellent physical properties, so how can there be linear cracking, once this phenomenon occurs, the entire pipeline will be damaged to a certain extent. So what exactly causes pipe cracking?
First of all: the selection of materials and the control of the production process account for the main reason: polyethylene pipes are generally black, many manufacturers just take advantage of this, in order to reduce costs, add a large number of recycled materials, garbage materials, etc., resulting in the quality of the pipe itself declines, the flexibility of the pipe decreases, and the problem of cracking.
Secondly: cracking will also occur during construction and use, construction should be carried out according to specifications, and the design pressure of the pipeline should be consistent with the actual working pressure, for example, the purchased pipeline can only withstand 10 kg of pressure, but the actual water supply process pressure is far greater than 10 kg, which will also lead to cracking problems.
Once the pipeline cracks, it is quite harmful for the later use, once the crack starts, the crack will expand rapidly along the length of the pipeline, so we must shop around when purchasing, not blindly pursue **, choose a conscientious manufacturer, and standardize the construction of reasonable use!
