Inflatable Bag Weld Purge System


Range: 2" to 48"

Our Inflatable Pipe Purging Systems are designed to maximise time and minimise cost. Two inflatable bladders are joined by a braided gas hose. Using inert gas(such as argon) to first inflate both bladders on either side of the weld before releasing the gas(via a pre set valve) into the chamber they have created, forcing the oxygen out through exhaust tubes built into the bladders. The Oxygen is removed so the welder can weld the pipes without the risk of oxidisation. Once the gas flow is stopped the bags deflate and are easily removed from the pipe. Used in conjunction with our Oxygen Monitors, these systems enable the welder to produce highest quality welds in very little time and with no Oxidisation.

Technical Data Sheet

Rapid Purge Inflatable Weld Purge System


Range: 8" Upwards

The Rapid Pipe Purge systems take gas purging to the next level. The inflatable bladders are housed in heat resistant material, the unique design of these systems means that the area to purge is further reduced, by localising it to the weld root. Whether 8” or 80” pipe, these lightweight, yet rugged systems allow easy withdrawal from the pipe once deflated, even round bends and elbows! For fast, precise welds, with minimal gas usage, Rapid Purge is the solution for every pipe welder when the weld quality of exotic material is critical. Used in conjunction with our Oxygen Monitors, these systems enable the welder to produce highest quality welds in very little time and with no Oxidisation.

The Double Seal Silicon Weld Purging System

The Triple Seal System

Range: 1½" - 12"

The PIPE Ltd Double Seal System is the latest innovation in purging processes and has been designed to further reduce both inner gas use and purging time. The gas is diffused into the chamber through a built in diffuser in the rigid, flexible or spring braided hose and exits through the exhaust holes in the first triple disc unit. This process of gas diffusion provides an even flow of gas and prevents any gas turbulence behind the weld, thereby minimising the risk of oxygen in the welding chamber while, at the same time, achieving an extremely short purge time. Used in conjunction with our Weld Purge Monitors, these systems will give you extremely short purge times result in valuable cost savings in gas and time.

Gas Cylinder - Silicon Weld Purging System

Gas Cylinder Purging System

Range: 8" - 40"

Gas Cylinders are available for pipes from 200mm to 1000mm diameter. These tools have two heat-resistant sealing lips, taking 340ºC for up to one hour.
These cylinders have extremely short purge times of 1 ½ - 2 ½ minutes for all dimensions.

The Gas cylinders are designed with pull-through balls to enable the unit to be easily retrieved out of a straight section of pipe, or a pipe with a series of bends or elbows.

The purge area is isolated, so there is no need to purge the entire area of pipe to be welded, thereby minimizing gas usage.

Expanding Pipe Stoppers/Bungs

Expanding Pipe Stoppers

Range: ¾" - 36"

A central spindle/shaft on which two plates are fitted with a natural rubber tyre (ring) between them, a wing nut on the shaft moving the two plates together compressing the tyre and making the seal in the pipe. Natural rubber tyres which can be substituted for different rubbers where additional chemical and/ or heat resistance is required. Alternative rubber ring options are: Silicone, Nitrile & Viton) These can also be supplied with a hollow shaft version for screwing on standard hose connections or for using fixed or free nipple caps. Expandable Pipe Stoppers are available manufactured from Nylon, Aluminium and Steel.
