Features
- DIN 28011 Titanium and Titanium Alloy Torispherical Heads for pressure vessels, formed from ASTM B265 Grades 1, 2, 5, 7, 9, and 23 titanium plate/sheet.
- Outstanding corrosion resistance to acids, alkalis, saltwater, hydrocarbons, and aggressive chemical environments (especially CP Grades 1, 2, and 7 with palladium stabilization).
- Superior strength-to-weight ratio combined with low density (4.51 g/cm³) for lightweight, high-pressure vessel components.
- Precision torispherical geometry: crown radius CR = Do, knuckle radius KR = 0.1Do, straight flange SF = 3.5t (or custom), outside diameter 500–5250 mm, thickness 3–40 mm.
- Excellent formability, weldability, and full compatibility with titanium piping, fittings, and vessel systems.
- Available in commercially pure and high-strength alloy grades for balanced corrosion resistance, strength, and ductility.
- Full NDE testing (UT/ET), chemical and tensile verification, plus EN 10204 Type 3.1 / 3.2 material certification available.
- Non-magnetic, non-reactive, dimensionally stable, and suitable for demanding service conditions after proper qualification and heat treatment.
