The outer edge of pipeline pig is elastotically sealed to the inner wall of pipeline. By using gas, liquid or pipeline transport medium as the power source, the pig in the pipeline is pushed forward to the end of pipeline or the pig receiver.
The outer edge of pipeline pig is elastotically sealed to the inner wall of pipeline. Using gas, liquid or pipeline transport medium as the power source, the pig in the pipeline is pushed forward to the end of pipeline or the pig receiver. When running, it maintains a fixed direction so that it can carry a variety of detectors and devices.
Improve the efficiency of pipeline transportation
For oil pipelines, solid impurities and wax in crude oil may accumulate on the pipe wall under certain conditions. For gas pipelines and multiphase flow pipelines, there may be hydration in the pipeline, which will reduce the efficiency of the pipeline and increase the loss of pressure energy. Through pigging operation, the efficiency of the pipeline can be improved.
It is applied to the pigging process before transportation to clean the stones, wood bars, and other matters left in the pipeline;
Cleaning and nitrogen replacement after natural gas lines go into operation;
Exhaust before the water pressure test and drainage after the test.
Raw oil, product oil, edible oil, natural gas, LNG, chemical materials, coal water slurry, sewage, running water, etc.
