Features
- DIN 28013 Titanium and Titanium Alloy Ellipsoidal Heads (1.9:1 / 2:1) 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 ellipsoidal geometry: crown radius CR = 0.8 Do, knuckle radius KR = 0.154 Do, straight flange SF = 3t (or per request), outside diameter 500–5250 mm, thickness 3–40 mm for even stress distribution and reduced stress concentration.
- 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, with smooth surface for easy cleaning and sterilization; suitable for demanding high-pressure and high-temperature service after proper qualification and heat treatment.
