Global pipeline solutions provider T.D. Williamson (TDW) introduced the ProStopp™ DS isolation tool, the first double block and bleed technology for the gas distribution market. It is currently available for 6-inch to 12-inch pressurized carbon steel pipelines.
The ProStopp DS isolation tool achieves a double block and bleed isolation utilizing two plugging heads with a bleed port in between. This allows the product to bleed through the housing so there is less hardware on the line. The new technology will help operators keep their promise to safely deliver energy across the globe.
ProStopp DS isolation technology features a hydraulically activated energized 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.
The ProStopp isolation tool is designed from schedule 10-60 pipe and is rated to 19 bar (285 psi). It is compatible with TDW valves and fittings.
