Pigging Valve Known as Trunnion Block-Mounted Ball Valve

Pipeline pigging Valve

1. Specification

The petroleum pipeline pigging Valve is a special valve used for cleaning petroleum pipelines. It has the following characteristics:

1.1 Reliable sealing performance to prevent oil leakage during the cleaning process.

1.2 High corrosion resistance to withstand the corrosive medium in the petroleum pipeline.

1.3Simple structure, easy to maintain and operate.

4. Application scenarios

The petroleum pipeline pigging Valve is suitable for the following scenarios:

4.1 Petroleum pipeline cleaning: the cleaning medium such as high-pressure water, chemicals, etc., can be introduced into the pipeline through the pigging Valve for cleaning.

4.2 Petroleum pipeline maintenance: during the pipeline maintenance process, the maintenance material such as lubricating oil, sealant, etc., can be introduced into the pipeline through the pigging Valve.

4.3 Petroleum pipeline renovation: during the pipeline renovation process, the new pipeline can be connected to the existing pipeline through the pigging Valve.
