This is a plug that allows for localized pressure testing after welding in flange construction. [Maximum pressure value: 15.5 MPa]
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.
