How to control the cleanliness of installed pipes

1, the installed pipeline rust removal can be through the compressed air blowing, the surface of the floating rust removal; if the cleanliness requirements are very high, can be removed in sections to pickling, if not, it is recommended to use the cycle of pickling method, this method needs to be done to make some temporary measures.

2, degreasing can be done by systematic circulation.

Pipe cleaning methods:

1, chemical cleaning: chemical cleaning of the pipeline is the use of chemicals, the pipeline is a temporary transformation, with temporary pipelines and circulating pumping stations from the two ends of the pipeline for the cycle of chemical cleaning. The technology is flexible, no requirements on the shape of the pipeline, fast, thorough cleaning and so on.

2, high-pressure water cleaning: the use of high-pressure water jets above 50Mpa, high-pressure water jets on the inner surface of the pipeline dirt stripping cleaning. The technology is mainly used for short-distance pipeline, and pipeline diameter must be greater than 50cm or more. The technology is characterized by fast speed and low cost.

3, PIG pipe cleaning: PIG industrial pipe cleaning technology relies on the pump to promote the fluid generated by the impetus to drive the PIG (pipe cleaner) in the pipe forward, the accumulation of dirt in the pipeline out of the pipe, so as to achieve the purpose of cleaning. The technology is widely used in various types of process pipelines, oilfield oil and steam pipelines and other cleaning projects, especially for long-distance transmission of fluid pipeline cleaning, with other technologies can not be replaced.
