Quick purging pipes for perfect welds Waiting for pipes to be purged ready for welding can take many hours, depending on the diameter of the pipe being welded and the method chosen for purging. purging the pipe, which was costing a considerable amount in time and gas costs. With the help of the QuickPurge the pipe was purged in just 55 minutes. The dramatic savings in time and gas paid for the system in just one weld.”

Using IntaCal ® combined with the integrated PurgeGate ® device makes it possible to safely inflate the dams with argon gas, for purging the space between the dams where the weld joint is located. With PurgeGate, burst dams are prevented in the event of undue pressure increase or accidental flow increase of the purging gas. All systems are manufactured as standard with a hose for connecting a Weld Purge Monitor ® , which can read oxygen levels down to as low as 10 ppm, depending on the model. Materials used in the manufacture of QuickPurge are resistant to the higher weld temperatures present, and they do not outgas, preventing weld contamination. For pre-heated chrome steel and high strength stainless steel pipe joints, HFT designs and manufactures the HotPurge™ range for a higher and longer temperature exposure.

Huntingdon Fusion Techniques (HFT) designs and manufactures a range of QuickPurge ® inflatable pipe purging systems that reduce waiting times. The company was recently tasked with a special project in the USA, where pipes with 90° elbows, up to 54" OD, were required to be purged. Georgia Gascoyne, CEO at HFT, said, “We manufactured QuickPurge systems with longer sleeves so that they could easily be pulled around the sharp bends in the pipework. The welders were previously spending half a day

QuickPurge has an additional gas input line, which allows extra purge gas to be introduced, achieving a faster purge down to the lowest oxygen levels. QuickPurge is suitable for purging tube, pipe and pipeline joints over 6" diameter, where oxygen levels are required to be as low as 100 parts per million (ppm) or less. HFT’s design means that zero colour welds will be achieved, and there will be no loss of corrosion resistance caused by oxidation.

Preventing pipe damage during handling and transportation

transport, storage and construction. These segments contain pipe closure, bevel protection, cross bracing, flange protection, pipe handling, anti- corrosion, pipe transport and storage, and pipe coating. In addition to supplying products, Dhatec is a knowledge partner for support, advice and training to improve logistic operations in the supply chain of line pipes anywhere in the world. It is an expert in optimising line pipe logistics and reducing associated costs within pipeline projects. The organisation operates from a client-centric perspective, in which it recognises that each situation is different and needs its own approach. In this way

In the global supply chain of pipeline projects, pipes travel long distances and are stored, handled and transported multiple times before they arrive at the construction site. This handling, storage and transportation of pipes carries risks of damage to the pipe or its coating, quality loss, corrosion and even accidents. Dhatec, a specialist in line pipe logistic solutions, delivers products to prevent pipes from being damaged, from the production mill to the construction site. This includes safe handling, as well as transport and storage of pipes during the whole supply chain of the line pipe.

Dhatec can offer optimal service, fitting the client’s needs and wishes.

Dhatec will be exhibiting at Tube Düsseldorf, on stand 4G18.
