XABLD 8-12 - 8-12 Inch Inflatable Double Seal Pipe Purge System

Professional Pipe Purging Solution for High-Quality Welds

The X-Expendable Double Bladder Purge Bag System (SKU: XABLD 8-12) is an essential apparatus for industrial pipe fabricators seeking to maintain the highest standards of weld quality while optimizing operational costs. Designed specifically for pipe diameters ranging from 8 inches to 12 inches, this system creates an isolated chamber within the pipe, allowing for the efficient displacement of oxygen with inert gas (typically Argon). This process is critical when welding reactive metals such as stainless steel, titanium, and nickel alloys, where the presence of oxygen can lead to oxidation, discoloration, and structural defects known as 'sugaring'.

Engineered with a double bladder configuration, the system provides a redundant seal that ensures the purge chamber remains airtight, even in challenging field conditions. The bladders are connected by a flexible bridge, allowing the unit to navigate bends and elbows within the piping system easily. A key differentiator of this model is its high-heat resistant construction. Unlike standard rubber or nylon balloons, the X-Expendable system utilizes advanced heat-resistant fabrics that can withstand the elevated temperatures generated during the welding process, permitting placement closer to the heat affected zone (HAZ) for a smaller purge volume.

By minimizing the volume of pipe that needs to be purged, this system significantly reduces the amount of inert gas required and the time needed to reach the desired oxygen levels. This translates directly to lower consumable costs and increased throughput. The system is fully reusable and collapses for compact storage, making it a durable asset for any MRO or fabrication toolkit.
