When using cap welding for the closure method during pressure testing of pipes, tubes, and conduits, we recommend using this Grip Tight plug for closure. It can achieve closure up to high pressure simply by assembling the plug to the end of the tube/pipe. (Max pressure resistance: 96MPa) ● This will significantly reduce labor (cost). There is no need for the series of tasks involved in cap welding, cutting, or beveling; after assembling the plug and conducting the test, you only need to remove the plug. Additionally, the attached materials include plugs that can be used for localized pressure testing during the replacement of existing flanges, so please feel free to ask any questions. *For more details, please download the PDF or contact us.
