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 clean the inner surface dirt of PE mine pipe with high pressure water jet. This technology is mainly used in short distance pipeline, and the diameter of the pipe must be more 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 pigging: PIG pigging technology is driven by the pump to drive the fluid to generate the driving force to drive the PIG (pipe cleaner) to move forward in the pipe and to drain dirt outside the PE mining 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 chemical reagents, temporary transformation of pipelines, temporary pipes and circulating pump stations from the two ends of the pipeline for chemical cleaning.
