Technology & Features
Highest-quality corrugated tubes built with 18 years of titanium processing know-how and precision manufacturing technology.
Titanium Grade Comparison
Choose the optimal grade for your application and environment.
Grade 1
Highest-purity commercially pure titanium. Best ductility — ideal for complex shape forming.
Key Applications
Semiconductor piping, medical devices, food & pharmaceutical piping
Grade 2
The most widely used commercially pure titanium. A perfect balance of strength and formability.
Key Applications
Chemical / petrochemical piping, marine piping, heat exchangers
Grade 7
Palladium (Pd) 0.12–0.25% alloy. Unique corrosion resistance in reducing acid environments (HCl, H₂SO₄).
Key Applications
HCl / H₂SO₄ transfer, strong-acid chemical plants, nuclear
Grade 9
Ti-3Al-2.5V alloy. 30% higher strength than commercially pure titanium. Ideal for lightweight, high-strength piping.
Key Applications
Aerospace piping, high-pressure fuel lines, defense
Rigorous Process, Perfect Quality
Every stage from raw material receipt to shipment is strictly controlled.
Material Receipt & Inspection
Raw material quality verified through mill certificate review, elemental analysis (XRF), and 100% wall thickness measurement.
Hydroforming
Uniform corrugated shape produced by high-pressure fluid hydroforming. Integrated structure — no welding.
Heat Treatment (when required)
Vacuum annealing to relieve forming stresses. Optimises corrosion resistance and ductility.
End Fitting Welding
Connection ends such as sockets and flanges fully joined by TIG welding with inert gas back-purge.
Pressure & Leak Testing
100% individual product inspection via hydrostatic test (working pressure × 1.5×) and helium leak test.
Final Inspection & Packaging
100% dimensional measurement and surface condition check, then anti-rust packaging. Mill sheet and test certificate enclosed.
Quality Testing Beyond International Standards
Every product passes 6 quality tests before shipment.
Hydrostatic Test
ASME B31.3Working pressure × 1.5×, held for 10 minutes
Leak Test
ISO 15848Helium leak test (Leak Rate < 10⁻⁶ mbar·L/s)
