Ultimate corrosion resistance with unmatched strength-to-weight ratio
Titanium is not chosen to save money — it is chosen to eliminate failure.
ASTM B338 / B862 titanium welded tubes are specified where stainless steel, duplex, and even nickel alloys struggle to deliver long-term reliability.
These tubes combine:
INOX STEEL INDIA supplies project-grade titanium welded tubes engineered for critical service environments.
Titanium welded tubes are manufactured from titanium strip or plate using high-purity inert-gas welding (TIG / Plasma) under controlled environments.
The result is a tube with:
Covered by:
Titanium is approximately 45% lighter than steel, yet delivers comparable or higher strength.
Titanium heat-exchanger tubes routinely achieve 20–40+ years of service life.
