Titanium and titanium alloy heads (Titanium Head/Titanium Cap) are indispensable pressure-bearing components used in pressure vessels, heat exchangers, reaction kettles, and pipeline systems. Leveraging the superior corrosion resistance, high strength-to-weight ratio, and high-temperature resistance of titanium materials, titanium heads are widely employed in industries such as chemical engineering, offshore engineering, pharmaceuticals, food processing, chlor-alkali production, and aerospace. Utilizing the industrial advantages of Baoji – home to "China Titanium Valley" – Baoji Aulister Import & Export Co., Ltd. specializes in the deep processing of non-ferrous metals including titanium, tantalum, niobium, molybdenum, and nickel. The company provides global customers with custom manufacturing services based on their design specifications for products such as TA2 semi-spherical pure titanium heads, elliptical titanium metal heads, and stamped titanium tube caps.
1. TA2 Hemispherical Pure Titanium End Cap: Manufactured from high-quality TA2 (Gr.2) pure titanium sheets through integrated stamping or spinning forming processes, this end cap features uniform wall thickness, a smooth surface finish, and exceptional pressure-bearing capacity – making it ideal for use as an end cover on pressure vessels operating under high-pressure or highly corrosive conditions.
2. Elliptical Titanium Alloy Head (EHA/EHB): A standard elliptical head featuring moderate depth and stable manufacturing – the most commonly used type of head for chemical storage tanks and reaction vessels; can be manufactured in accordance with standards such as GB/T 25198 and ASME.
3. Stamped titanium pipe caps (Pipe Cap) – designed for sealing pipeline ends; available in a wide range of specifications covering small to large diameters, including various types such as flat end caps, hemispherical pipe caps, and elliptical pipe caps; features excellent weldability.
