Heavy duty orange Flameshield Proban covers, twin bag purge set. Purge and vent inter space between the bags to enhance pipe weld quality and minimise Argon/Helium purging costs. Bag inflation and purge functions using twin supply hoses to firstly inflate the secondary and primary bags together and secondly purge the inter space, passing through a Sintered fitting to diffuse the gas and reduce turbulence. (Avoids the use of a Pressure Relief Valve and possibility of over inflation of purge bags and simple to operate). Aluminiumised cloth end disks and Umbilical Fire Sleeve protection options for higher temperature and molten metal exposure.
