PE矿用管清洗方法：
PE cleaning method for mine pipe:
1、高压水清洗：采用50Mpa以上的高压水射流，对PE矿用管内表面污垢进行高压水射流剥离清洗。该技术主要用于短距离管道，并且管道直径必须大于50cm以上。
1. High pressure water cleaning: high pressure water jet above 50Mpa is used to remove the dirt on the surface of PE mining pipe by high pressure water jet. The technology is mainly used for short distance pipelines, and the diameter of pipelines must be greater than 50cm.
2、PIG清管：PIG清管技术是依靠泵推动流体产生的推动力驱动PIG（清管器）在管内向前推动，将堆积在PE矿用管内的污垢排出管外，从而达到清洗的目的。
2, PIG clear pipe: PIG pipe cleaning technology is to rely on the pump to drive the fluid driven driving force driving PIG (pipe cleaner) forward in the tube, will accumulate in the PE pipe in the dirt discharge pipe, so as to achieve the purpose of cleaning.
3、化学清洗：化学清洗PE矿用管是采用化学药剂，对管道进行临时的改造，用临时管道和循环泵站从管道的两头进行循环化学清洗。
3, chemical cleaning: chemical cleaning PE mine pipe is a chemical agent, the temporary transformation of the pipeline, the use of temporary pipes and circulating pump station from two sides of the pipeline to carry out cyclic chemical cleaning.
