Aluminium vs GI Piping for Compressed Air
Aluminium vs GI Piping for Compressed Air
GI compressed-air lines are common in older Indian factories. Aluminium modular piping is the usual upgrade when rust, pressure loss and slow modification start costing production.
Key takeaways
- GI rusts from condensate; aluminium resists internal scale.
- Pressure drop rises as GI roughens; aluminium stays smoother longer.
- Modular aluminium installs and expands faster than threaded GI.
- ITT stages GI-to-aluminium upgrades for Faridabad plants with limited downtime.
GI piping reality in plant air systems
Galvanized iron was a default for utilities. In compressed air, condensate still drives internal corrosion over years. Scale narrows bore, sheds particles and pairs poorly with leaky threaded joints—raising compressor workload.
Aluminium vs GI piping for compressed air is therefore a lifecycle decision, not only a material price comparison.
Where aluminium wins for plant teams
- Cleaner air path without rust flake
- More stable pressure at distant drops
- Faster installs with modular fittings
- Easier machine adds without rethreading whole branches
- Lower long-term distribution maintenance

Practical upgrade approach
Replace the worst ring or hall first, keep critical production fed, then expand. ITT plans isolation, transitions and testing so GI and aluminium can coexist briefly during migration.

Frequently asked questions
Is GI ever acceptable for new compressed air lines?
Some low-risk utility cases still use GI, but most new industrial air networks prefer aluminium for cleanliness and expansion. ITT advises per duty.
Will aluminium fix a wet air problem alone?
No. Fix drying and drainage too. Aluminium stops rust contamination; dryers and drains stop the moisture root cause.
How do I justify aluminium vs GI cost?
Include energy from leaks/pressure drop, downtime for modifications, filter and tool wear, and labour—not only rupees per metre of tube.
