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.

In plant maintenance piping work, pressure tests of weld points, purging during welding, and upstream monitoring can be performed. - Local implementation with a plug is possible, eliminating the need for ancillary work. - Significant reduction in labor (cost) is achieved. - It can be used repeatedly multiple times. - Local testing allows for a reduction in the amount of medium used. Pressure tests can be conducted on various shapes of flanges, such as neck flanges and slip-on flanges. *For more details, please download the PDF or contact us.

During flange replacement work at plant piping maintenance sites, localized welding points can withstand pressure tests up to 15.5 MPa. - Localized response with a plug eliminates the need for ancillary work. - Significant reduction in labor (cost) is achieved. - Can be reused multiple times. - Localized testing allows for a reduction in the amount of medium used. This is a plug compatible with weld neck flanges. We also have high-lift flange welding test plugs compatible with slip-on types. *For more details, please download the PDF or contact us.

By utilizing pressure test plugs from Curtis Wright in the United States, the man-hours required for pressure testing can be significantly reduced. We introduce three types of plugs for different applications. ● For closing pipe ends: Grip Tight ● For flange local use: DBB plug ● For flange local use: High lift flange plug 【Features】 ■ Grip Tight Can seal up to high pressure (maximum 96MPa) simply by attaching the plug No need for a series of tasks such as cap welding/cutting/preparation Reusable ■ DBB Plug Allows simultaneous isolation of the upstream side and pressure testing of the weld point Pressure testing can be performed locally only at the welding point → Achieves reduction in media volume and simplification of construction ■ High Lift Flange Plug Allows purging during welding and upstream monitoring Compatible with various flange shapes (neck flanges, slip-on, etc.) Pressure testing can be performed locally only at the welding point → Achieves reduction in media volume and simplification of construction *For more details, please download the PDF or feel free to contact us.

Curtiss-Wright Corporation in the United States offers maintenance technologies with special features called "Pop-A-Plug" and "High Lift Flange Plug." 【Pop-A-Plug】 The Pop-A-Plug allows anyone to easily seal heat exchanger tubes in high-pressure equipment without the need for welding. - No welding required: Since welding is not necessary, there is no need for fire permits or inspections related to welding. - High-pressure compatible: It can withstand a maximum pressure of 48MPa and is used in various plant equipment. - No qualified personnel or skilled techniques required: With engineered plugs and specialized tools, anyone can achieve the same quality of crimp sealing. - Reduced labor: Significantly shortens work time and equipment recovery time. 【High Lift Flange Plug】 This is a tool for local pressure testing of flange welds, capable of testing up to high pressure. - Capable of testing up to high pressure: Flange #150 is 3.1MPa, #300 is 7.7MPa, and #600 is 15.5MPa. - Compatible with various flange shapes: WN, SO, SW. There are already numerous achievements, particularly in the maintenance sites of domestic petrochemical plants. *For more details, please feel free to contact us.
