High-pressure test plug for pipe flanges
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.

Applications/Examples of results
Curtis Wright Corporation / EST Division is a specialized manufacturer of pipe seal technology headquartered in the United States, handling various shapes of test plugs used for high-pressure testing of pipelines and plant equipment. The biggest feature of these plugs is their ability to test up to high pressure values that are not available from other companies. (They can be used for both hydrostatic and leak testing.) High-lift flange welding plugs are adopted mainly in flange construction at plant maintenance sites both domestically and internationally.
