Pig valve-Gas valve series-燃气阀厂家-上海冠环阀门制造有限公司

Product Overview
The pigging valve mainly solves the problem of sedimentation or formation of dirt on the inner wall of pipelines during long-term use. The deposition of these dirt on the pipeline wall will increase the resistance of the fluid during transportation. Lay a new pipeline, clean all residues inside the pipeline before operation, and apply rust and anti-corrosion coating on the inner wall of the pipeline to ensure smooth and unobstructed flow of the pipeline.
