PU Fully Coating Polly Pig Bare Bubble Spiral Brush Foam Pig

Descaling Foam Pig is a common foam pig. It is mainly used for pipeline inspection and cleaning. It is one of the most practical pipeline equipment.

Its background is not difficult to understand. With the rapid development of China's oil and natural gas industry, the construction of oil and gas pipelines is advancing by leaps and bounds. At present, pipeline transportation has become the main mode of onshore oil and gas transportation in China.
 

However, as the service life of the pipeline increases. On the one hand, sediment accumulation in the pipeline. This reduces the effective flow area of the pipeline and even leads to blockage. On the other hand, factors such as occupation, geological change, etc. will also lead to deformation such as depression and bending of the pipeline. This will change the internal section shape of the pipe. Pig is a kind of equipment which relies on pipeline fluid as power. It can push it to run in the pipeline, remove the sediment in the pipeline and detect the pipeline.

• Pig mainly for pipeline maintenance and cleaning, mainly including polyurethane foam and cup type pig;
• Pig mainly aimed at pipeline inspection, including magnetic inspection pig, etc. The basic structure of the intelligent detection pig is a steel framework with poor passing capacity. Therefore, it is easy to cause pipe blockage. Descaling Foam Pig is generally bullet shaped. It is light, shrinkable and has good trafficability. Therefore, it can pass through pipelines with complex conditions, but it does not have the detection function.
