TDW ProStopp™ DS isolation tool for pressured carbon steel pipes

“Because 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.

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 number of cost- and time- saving advantages.

Global pipeline solutions provider TD Williamson (TDW) 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

HFT launches pipe purging monitor that ensures accuracy

The PurgEye 200 now features PurgeNet™, a networking device that allows accessories to be connected. These include an automatic welding machine interface so that the oxygen level in the vicinity of the weld can be continuously monitored and the welding machine can be

Pipe purging expert, Huntingdon Fusion Techniques, has launched its PurgEye ® 200 Weld Purge Monitor ® , which it believes will ensure zero colour, non- oxidised welds every time, with accurate readings down to 10 ppm. Luke Keane, technical sales manager for HFT ® , said: “The PurgEye 200 IP65 rated is our most advanced, portable, hand held, 10 ppm weld purge monitor, perfect for achieving high quality titanium, zirconium, high specification stainless steel and nickel alloy joints every time.”

audio alarms for rising or falling oxygen levels, the PurgEye 200 comes complete with a faster response long life sensor and integral electro- mechanical pump to extract samples from a weld purge zone, in the event that there is insufficient flow rate or positive pressure to activate the sensor correctly. PurgeLog Software is provided to record Weld Purging results and provides quality control documents for each weld. Huntingdon Fusion Techniques www.huntingdonfusion.com

switched on or off according to pre- set oxygen levels, external audible and visual warning devices and a dew point monitor. The PurgEye 200 has an OLED (organic light emitting diode) display, which will give bright, clear and sharp readings for viewing at distances and wide angles. These OLED displays mainly use symbols, rather than text-based descriptions, making the menus internationally comprehensible. This instrument is able to operate from rechargeable batteries or mains power. Along with loud, pre-settable
