TDW ProStopp™ DS isolation tool eliminates leaks in pipe weld seams

number of cost- and time-saving advantages. “Because the energised seal accommodates multiple inner diameters, it takes the guesswork out of tool configuration while drastically reducing inventory needs,” Mr Ragsdale said. “The built-in chip sweep helps ensure a leak-proof seal while also reducing operation requirements. And because the tool is ground-operated, the technician makes fewer trips up and down the ladder, completing jobs faster and with less risk.” The ProStopp isolation tool is designed from schedule 10-60 pipe and is rated to 19 bar (285 psi) and is compatible with TDW valves and fittings.

GLOBAL pipeline solutions provider TD Williamson has introduced the ProStopp™ DS isolation tool, which the company believes is the first double block and bleed technology for the gas distribution market. Currently available for 6” to 12” pressurised carbon steel pipelines, the ProStopp DS isolation tool achieves a double block and bleed isolation utilising two plugging heads with a bleed port in between. This allows product to bleed through the housing so there is less hardware on the line. “Gas distribution is critical to everyday life and shutdown is never an option,” Ryan Ragsdale, senior product manager, hot tapping and plugging technology said. “The ProStopp DS solution is a reliable way to ensure a safe work zone during pipeline repair and modification, without interrupting service to downstream customers.”

The new technology, which will help operators keep their promise to safely deliver energy across the globe, features a hydraulically activated energised seal that conforms flawlessly to multiple internal pipe diameters. The variable design increases the likelihood of first-time sealing success and eliminates leaks in even tough crevices and weld seams. According to Mr Ragsdale, the ProStopp DS isolation tool draws on the company’s decades of isolation expertise and offers operators a
