Forming Gas Pressure Regulators – Superior Root Shielding for Stainless Steel and Pipe Welding

Forming gas pressure regulators provide precise flow and pressure control for purging gas mixtures (typically nitrogen with a low hydrogen percentage, e.g., N2/H2 95/5) used during TIG welding of stainless steel, titanium, and high-alloy pipes. Forming gas purges oxygen from inside the pipe or vessel, preventing root oxidation and sugaring. We supply professional forming gas regulators featuring precise flowmeter tuning.

Why Choose High-Quality Forming Gas Regulators?

Accurate dosing of purging mixtures containing hydrogen requires dependable, certified pressure control:

• Precision Tube Flowmeter (Rotameter): Enables accurate low-flow adjustment in l/min for economical pipe purging.
• Hydrogen-Safe Engineering: Meets safety standards required for handling forming gas mixtures containing hydrogen.
• Constant Flow Rate: Prevents turbulence and pressure jumps at the weld root, producing shiny, oxide-free root pass welds.
• Heavy-Duty Body with Clear Gauges: Provides instant monitoring of cylinder gas reserve and target shielding flow.

How to Choose a Forming Gas Regulator?

• Flowmeter Style: Column flowmeters are highly recommended for pipe purging to monitor exact flow rates.
• Cylinder Thread Compatibility: Verify thread direction based on your specific forming gas bottle valve specs.
