High-pressure plugs for pressure testing of pipes and flanges for the oil and gas industry.
CURTISS-WRIGHT Corporation HIGH LIFT FLANGE/WELD TEST PLUG
After the welding of the flange construction, the localized pressure test reduces the risk of leakage.
In the oil and gas industry, the safety of piping is the top priority, and leaks can lead to serious accidents. Particularly, the reliability of flange connections under high-pressure conditions is essential for the stable operation of plants. Our high-pressure pipe and flange pressure test plugs reduce leak risks and enhance safety by allowing localized pressure testing after welding. 【Usage Scenarios】 - Pressure testing of piping after welding during plant maintenance - Purging during welding and monitoring on the upstream side - Compatibility with various flange shapes, such as neck flanges and slip-on flanges 【Benefits of Implementation】 - Reduction of ancillary work through localized testing - Significant reduction in man-hours (cost) - Decreased environmental impact through reduced media usage
