PLEASE CALL FOR PRICE.We recommend the use of inflatable pipe purging dams when welding schedule pipework and all other kinds of cylindrical vessels. These inflatable pipe purging dams work really well with the Weld Gas Analyser and used together they will help to eliminate all oxidised weld roots in stainless steel and other exotic metals such as Titanium.Weldwide Inflatable Purge Systemsare an efficient and economical TIG welding purge dam solution. These purge systems can be easily placed into pipes and inflated with Argon gas through the connecting hose. Once inflated, the purge dams create a safe, airtight seal. The Inflatable purge dams are also equipped with a pressure valve that releases the Argon gas when the pipe has been dammed to purge the weld chamber of the pipe. Requiring a minimal amount of gas to seal pipes compared to purging the whole pipe, inflatable weld purge systems reduce the cost of gas and labour.Strong stitching on dam bags, resistant to tearing on burrs or nicksFire and scorch resistant from hot metal.Reinforced pull loops to easily pull the purge system out of the pipe when welding is finishedDurable metal connections and internal fittings. The connecting hose is armoured by stainless metal braiding.The welder can adjust the purging gas pressure against the weld root to get the desired weld profile on the inside bore of the pipe.Made in the United Kingdom to International ISO standards.We are New Zealand agents for the Weldwide Solutions range of Pipe Purging Equipment.
