Nitrogen & Inert Gas Piping Installation

Nitrogen is the most commonly used inert gas in industry. We install N2 distribution networks from bulk tanks and on-site generators to points of use. Applications include food packaging (Modified Atmosphere Packaging), laser cutting assist gas, electronics soldering, chemical blanketing, and tire inflation. We use SS304 or SS316L with orbital welded joints to maintain nitrogen purity (typically 99.99% or higher). For high-flow applications, we size piping to maintain pressure drop below 0.5 Bar from source to the most remote point of use.

Argon is essential for TIG and MIG welding operations. We install argon distribution systems from cylinder manifolds or bulk tanks to individual welding stations. Proper argon piping eliminates the need for individual cylinders at each workstation, reducing gas waste by 30-40% and improving safety. For large fabrication shops, we install ring-main argon distribution with drop points at every welding bay — each with its own pressure regulator and flow meter.

CO2 piping serves food and beverage carbonation, welding, fire suppression, and cooling applications. We install insulated CO2 lines for both gaseous and liquid CO2 distribution, ensuring proper pressure regulation and safety relief at all points. Liquid CO2 piping requires vacuum-insulated or foam-insulated lines to prevent the CO2 from warming and converting to gas, which would cause dangerous pressure buildup.

Many industrial processes use gas mixtures rather than pure gases — for example, Argon/CO2 (75/25) for MIG welding of carbon steel, or N2/H2 (forming gas) for electronics manufacturing. We install gas mixing systems with inline analyzers that verify mixture ratios in real-time, along with distribution piping to deliver the mixed gas to all points of use.

The piping between your gas source and point of use is just as important as the source itself. We install piping connections for all gas supply types:

• Cylinder Manifolds: Automatic changeover manifolds for uninterrupted gas supply. Primary and reserve banks with automatic switchover when primary bank empties
• Bulk Storage Tanks: Cryogenic liquid N2 and Ar tanks with vaporizers. We install the piping from vaporizer outlet to building distribution header
• On-Site Generators: PSA (Pressure Swing Adsorption) nitrogen generators and membrane systems. We handle the piping from generator to receiver tank to distribution
• Electrolyzers: For hydrogen generation from water — we install the high-purity H2 piping from electrolyzer to storage and compression systems

Inert gases are invisible and odorless — a nitrogen or argon leak in an enclosed space can silently displace oxygen and cause asphyxiation. Hydrogen adds flammability and explosion risk. Our installations always include:

• Gas Detection: Fixed oxygen depletion monitors in all areas where inert gas piping runs through enclosed spaces. Audible and visual alarms at 19.5% O2
• Emergency Shut-Off: Manual and automatic isolation valves at strategic points. Emergency push buttons at exits and near high-risk equipment
• Ventilation: Proper ventilation design for rooms containing gas equipment — ensuring air changes are sufficient to prevent dangerous gas accumulation
• Signage & Labeling: All gas piping color-coded per BS 1710 and labeled with gas name, direction of flow, and pressure at regular intervals
