Designed to enable the user to produce high quality, reliable and repeatable welding of stainless steel tube and pipe joints to ensure a very fast weld purge time and a very high quality weld root, free from oxidation and discolouration.
A 36″ diameter pipe will purge to below 0.1% oxygen in less than 10 minutes and all smaller pipes correspondingly faster. Dramatic savings of time, gas and money can be made by using these systems.
Due to the quality of the materials used, the Speedy Purge systems can be used over and over again further reducing manufacturing costs. As with all of inflatable purging systems, the Speedy Purge™ comes with pre-set valves, so are ready to use ‘straight out of the box’. And are developed specifically to enable high speed purging for any pipe welding application.
Features and advantages
- Typical purge times of less than 10 minutes
- The central sleeve’s unique “thru-bore” design minimizes the area to be purged, reducing the volume of gas required
- Friction-free coatings enable easy movement through pipes, including bends and elbows
- Ready to use, connects to a dedicated and regulated gas supply
- Flow rate options up to 80l/min through the twin preset purge valve
- Central strip (glow in the dark) for fast and accurate alignment to the weld area’s center point
- Inflatable dams and Umbilical hose covered with a heat-resistant material and insulated for temperatures up to 250 deg C.
Speedy Purge Heat Resistant System to 350º (500º for Short Periods),
The GBC Twin Purge Bag & Speedy Purge Systems are both offered in heat resistant versions. These are designed for applications where high temperatures are present during the welding process, including pre & post-heating operations. The systems provide heat resistance up to 350°C for periods up to 24 hours and can handle 500°C for brief intervals.
Like the standard range of inflatable purging systems, the heat resistant versions feature a luminous positioning band for quick centering and setup.
These systems can remain installed throughout the pre-heating, welding and post-heat treatment cycles, enabling continuous purging of the weld for up to 24 hours when needed.
