T.D. Williamson has introduced its ProStopp™ DS isolation tool, a double block and bleed technology for the gas distribution market. Available for 6–12 inch (152–305 mm) pressurised carbon steel pipelines, theProStopp™ DS isolation technology achieves a double block and bleed isolation by utilising two plugging heads with a bleed port in between.

This structure allows product to bleed through the housing, resulting in minimal hardware on the line and allowing operators to safely delivery energy.

TDW Senior Product Manager, Hot Tapping and Plugging Technology Ryan Ragsdale said gas distribution is critical to everyday life and a gas shutdown is never an option.

“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,” said Mr Ragsdale.

The technology features a hydraulically activated energised seal that conforms to multiple internal pipe diameters, increasing the likelihood of first-time sealing success and eliminating leaks.

“Because the energised seal accommodates multiple inner diameters, it takes the guesswork out of tool configuration while drastically reducing inventory needs,” said Mr Ragsdale.

“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™ DS isolation tool is compatible with TDW valves and fittings.
