Three types available for different purposes! A plug that reduces labor for piping pressure tests.
Achieve reliable closure even in high-pressure environments! Significantly reduce man-hours and costs during pressure testing.
By utilizing the pressure test plugs from Curtis Wright in the United States, the man-hours required for pressure testing can be significantly reduced. Three types of plugs are introduced 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 Simply attaching the plug allows for closure at high pressure (up to 96MPa) No need for a series of tasks such as cap welding/cutting/preparation Can be reused multiple times ■ DBB Plug Allows simultaneous isolation of the upstream side and pressure testing of the weld point Pressure testing can be performed locally at the weld processing point only → 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 at the weld processing point only → Achieves reduction in media volume and simplification of construction *For more details, please download the PDF or feel free to contact us.
