HFT pipe purging technology monitors down to 10ppm

developed and designed to use when welding titanium, zirconium, high specification stainless steel and nickel alloy joints, so that the user can produce metallurgically sound and oxide-free welds. Luke Keane, technical sales manager for HFT, said: “We’ve recently updated our range of weld purge monitors and most of which now include 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 switched on or off according to pre-set oxygen levels, an external audible and visual warning devices and a dew point monitor.” The PurgEye 200 has an organic light emitting diode display, which gives bright, clear and sharp readings for viewing at distances and wide angles and is able to operate from rechargeable batteries or mains power. technology for pipeline isolation and incorporate all of these benefits into one comprehensive product.” EVOLUTION features a thinner 1 / 8 " design and has been designed to minimise the difficulties which are often encountered when attempting to install thicker isolating gaskets. The full-coating encapsulation allows the gasket to be hydrotested and left in the pipeline with the same isolation properties as before it was tested. EVOLUTION’s coating, which is a GPT proprietary material, is abrasion and impact resistant and provides chemical resistance to H 2 S, steam, CO, CO 2 and other chemicals often found in oil

Huntingdon Fusion Techniques (HFT) has announced that its PurgEye ® 200 Weld Purge Monitor ® will ensure zero colour, non-oxidised welds are achieved every time with accurate readings down to 10ppm. The PurgEye ® 200 is a portable, handheld monitor which has been

The PurgEye also features loud, pre- settable audio alarms for rising or falling oxygen levels and comes 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. The Weld Purge Monitor reads down to 1ppm and is IP65 rated. PurgeLog™ Software is also provided to record weld purging results and provides quality control documents for each weld. Huntingdon Fusion Techniques www.huntingdonfusion.com and gas pipelines. The coating is fully encapsulated and prevents the need for expensive exotic cores as it eliminates contact to exposed metal. Rated to 500°F (260°C), EVOLUTION can operate under high temperatures. Tested comprehensively for safety, the product has API 6FB, 3 rd Edition Fire Test recognition. As with existing GPT high pressure isolation gaskets, EVOLUTION features: pressure energised seals, a fire safe Inconel 718 c-ring, built to match pipe bore, a short moment arm, moisture and humidity resistance, zero creep relaxation and a 316LSS core.

GPT unveils the next generation of isolation gaskets for easier installation

Garlock Pipeline Technologies (GPT), a manufacturer of critical pipeline sealing and electrical isolation products, has announced the unveiling of EVOLUTION™, said to be the next generation of isolation gaskets. EVOLUTION has been designed for easier installation, tight sealing, high- temperature operation, no permeation, hydrotesting isolation, fire-safety and chemical-resistance. “As its name implies, EVOLUTION is the next step in gasket technology and is poised to eliminate a number of issues that plagued gaskets in previous iterations,” said Tim Hurley, GPT senior global product manager. “EVOLUTION was designed to take the best available
