★Grip Tight★ Maximum pressure resistance value 96MPa! Directly conduct pressure tests by sealing pipes, tubes, and nozzles of equipment without the need for welding!
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 rating: 96MPa) ● This will significantly reduce labor (cost) efforts. 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.

basic information
When using cap welding for the closure method during pressure testing, we recommend the closure method with Grip Tight from Curtiss-Wright. This eliminates the series of operations involved in cap welding (cap welding/cutting/preparation) and allows for easy testing up to high pressure values. Additionally, Curtiss-Wright offers a variety of plugs, such as the DBB plug, which can withstand pressure tests up to 15.5 MPa and can be used for localized responses during flange replacement work at plant sites. These products are already widely used around the world, with a proven track record in thermal power plants, oil plants, nuclear plants, LNG plants, and more. Please feel free to contact us if you would like detailed materials or explanations. (You are also welcome to inquire about size selection and quotes.)

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.) We already have numerous overseas achievements, and they are used in plant sites in various countries and during the creation of new pipe units. Additionally, domestically, large equipment manufacturers in the plant sector have adopted them for pressure sealing of tube units and pipe units, as well as in petrochemical plant sites.
