T.D. Williamson (TDW) introduced its latest isolation innovation for the gas distribution market, the Polystopp Quick Connect system.

Lightweight and easy to use, it allows operators to isolate a polyethylene (PE) line twice as fast as other methods while preventing the damage associated with squeezing.

According to HT&P senior product manager Ryan Ragsdale, it takes less than 10 minutes to tap and isolate a pipeline with the Polystopp Quick Connect system. The technician can install the tapping, plugging and completion machines onto the valve in about 20 seconds each, and removal is just as fast.

“Faster isolation dramatically decreases job time and increases efficiency while preserving pipeline integrity, which maximizes value to the operator,” Ragsdale said.

The Polystopp Quick Connect system is extremely lightweight compared to previous solutions. All components are made of aluminum, including the valve and tapping, plugging and completion machines. That makes it light enough for a one-person lift operation.

Polystopp Quick Connect technology allows TDW to meet the needs of the PE market with something the industry has never seen before.

“Because we understand that the gas distribution industry is truly a lifeline for everyday citizens, TDW is constantly looking to develop technology that will enable operators to enhance pipeline integrity and do it faster, easier and more safely,” Ragsdale said.

The Polystopp Quick Connect system is available worldwide for 4-inch through 8-inch pipelines up to 10 bar (150 psi). Technology for 12-inch pipelines will be available in the near future.
