Orbital Service Gas Double Plugs
Orbital Service Forming Gas Double Plugs are professional purge sealing solutions designed to improve purge gas management during orbital TIG welding and high-purity pipe fabrication.
Manufactured from high-temperature silicone, these reusable double plugs create a secure seal inside the pipe, reducing purge volume while promoting consistent gas coverage throughout the weld zone. The result is more efficient purging, lower gas consumption, and cleaner, oxidation-free welds.
The system includes seven colour-coded plug sizes covering pipe inside diameters from 9 mm to 110 mm (0.35" to 4.33"), allowing operators to quickly select the correct plug for a wide range of stainless steel and process piping applications.
Supplied in a durable storage case and compatible with optional swirl nozzles, Forming Gas Double Plugs provide a practical solution for professional orbital welding environments where weld quality and purge efficiency are critical.

Frequently Asked Questions
What are Forming Gas Double Plugs used for?
Forming Gas Double Plugs are used to seal the inside of tube or pipe during orbital TIG welding, creating a smaller purge chamber that improves gas efficiency and weld quality.
How do double plugs reduce purge gas consumption?
By sealing both sides of the weld joint, the plugs significantly reduce the volume that must be filled with purge gas, allowing the system to reach the required purge level more quickly while using less gas.
What pipe sizes are supported?
The standard kit covers pipe inside diameters from 9 mm to 110 mm (0.35" to 4.33") using seven colour-coded plug sizes.
What materials are the plugs made from?
The plugs are manufactured from high-temperature silicone with a 35 Shore hardness, providing flexibility, durability, and heat resistance up to 300°C.
Can the plugs be reused?
Yes. The silicone construction is designed for repeated use in professional fabrication and orbital welding environments.
What is the benefit of the optional Swirl Nozzle Kit?
The optional Swirl Nozzle Kit (WiDü7) improves purge gas distribution inside the pipe, helping achieve faster, more uniform purging before welding.
