Uni-directional Scraper Pig is a common pig. It has 4 cups and a steel frame. The pig can remove soft dirt and dust from the pipeline. Its leather bowl has two functions. First, it has a good sealing performance. Therefore, it can completely separate the liquid or gas at both ends. Then a pressure difference will be formed at both ends of it, which can push it to run. Second, it can clean the sundries in the pipe and the dirt on the inner wall of the pipe.

Light Density Foam Pig, as the name suggests, is a pig made of low-density foam. It is the lowest density foam pig. So its main function is to absorb water in the pipeline. Low density makes it very absorbent. Users usually use it in the cleaning, drying and daily cleaning of pipelines.

Disc Pipeline Cleaning Pig can not only remove the liquid in the pipe but also remove the solid dirt. In addition, it can also install steel brushes and other accessories as required to enhance the pigging effect.
