T.D. Williamson introduces isolation innovation for gas distribution market

Technology

T.D. Williamson (TDW), a pipeline solutions provider, has introduced its latest isolation innovation for the gas distribution market, the POLYSTOPP Quick Connect system

The manufacturer said that the system allows operators to isolate a polyethylene (PE) line twice as fast as other methods while preventing the damage associated with squeezing.

It takes less than 10 minutes to tap and insulate a pipeline with the POLYSTOPP Quick Connect system, according to HT&P senior product manager Ryan Ragsdale. In about 20 seconds, the technician can install the tapping, plugging, and completion machines onto the valve, and removal is just as quick.

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

Compared with previous solutions the system is extremely lightweight. All components are made of aluminum including the valve and tapping, plugging, and completion machines. That makes it light enough for an operation with a single person lift.

“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 added.

The system is available worldwide for four-inch through eight-inch pipelines up to 10 bar (150 psi). The manufacturer stated that technology for 12-inch pipelines will be available in the near future.
