Titanium Semi Elliptical Head End Cap Grade 2 For Titanium Storage Tanks



A titanium semi-elliptical head end cap made from Grade 2 titanium is a specific component used in the construction of titanium storage tanks. Here is some information about these components:

  1. Grade 2 Titanium: Grade 2 titanium is a commercially pure titanium alloy that offers excellent corrosion resistance, high strength-to-weight ratio, and good formability. It is widely used in various industries, including chemical processing, aerospace, and marine applications. Grade 2 titanium is particularly suitable for applications requiring corrosion resistance and is commonly selected for storage tanks handling aggressive substances.

  2. Semi-Elliptical Head: A semi-elliptical head, also known as a semi-ellipsoidal dish end, is a curved vessel end that has a shape resembling half of an ellipse. It is used as a closure component for one end of a storage tank. The semi-elliptical shape provides structural stability, allows for efficient pressure distribution, and reduces stress concentrations. It is a common choice for storage tanks due to its favorable pressure-handling characteristics.

When constructing titanium storage tanks, using Grade 2 titanium for semi-elliptical head end caps combines the benefits of titanium, such as corrosion resistance and lightweight properties, with the specific head shape designed to optimize pressure containment and structural integrity.


It is important to follow industry standards and codes, such as API 650 for welded steel tanks or other relevant standards specific to titanium storage tanks, during the design, fabrication, and inspection processes. Adhering to these standards ensures the tanks meet the necessary quality and safety requirements for storing substances in a titanium storage environment.
