Curtiss-Wright GripTight Max Pipe Test Plug GTMAX20PSTD

The Curtiss-Wright GripTight Max Pipe Test Plug GTMAX20PSTD is a high-pressure isolation and testing device designed for hydrostatic pressure testing of pipes, pipelines, and pressure vessels. Manufactured by Curtiss-Wright EST Group, this plug provides a safe, reliable method to seal pipe ends, allowing for pressure tests up to 3,000 PSIG without welding or additional fittings. Key features include dual serrated grippers that engage the pipe's inner diameter for secure holding, a self-energizing seal that improves with increasing pressure, and compatibility with various pipe schedules (STD to SCH 100). It is ideal for applications in oil and gas, petrochemical, power generation, and shipbuilding industries where quick, leak-free testing is essential. Advantages over traditional blind flanges or welded caps include faster installation, reusability, and reduced labor costs, with no need for pipe end preparation. However, drawbacks may include its weight, which can make handling challenging without proper equipment, and the requirement for precise torque application during installation to avoid seal failure. This model is suited for 20-inch nominal pipes with an ID range of 19.17-19.72 inches, offering superior performance in high-pressure environments compared to lower-rated plugs from competitors like Petersen or EST's standard models. Based on image analysis, this unit appears used with visible wear and rust, but remains functional for industrial testing needs.
