What are the materials of the head?

A head is a component used to seal a container, commonly used in equipment such as pressure vessels, piping systems, and storage tanks. It is usually located at the end of the container and is used to close the container and keep the substances in it from leaking out.
The design of the head can be customized according to the shape and functional requirements of the container, and common types include flat head, convex head and cone head. The head is usually made of metal or alloy with high strength and corrosion resistance to ensure the safe operation of the container.

The commonly used materials for the head include the following:

1. Carbon steel: Carbon steel head is the most common choice, with high strength and corrosion resistance. It is suitable for low to moderate pressures and temperatures in general industrial applications.

2. Stainless steel: Stainless steel head has good corrosion resistance, suitable for applications requiring higher corrosion resistance, such as chemical industry, food processing and pharmaceutical fields.

3. Aluminum alloy: Aluminum alloy head has a light weight and good weldability, often used in low-pressure or non-corrosive media applications, such as air compressors and aerospace fields.

4. Titanium alloy: Titanium alloy head has excellent corrosion resistance and high strength, and is widely used in special environments in chemical, Marine and aerospace fields.

In addition, according to specific requirements, the head can also be made of other materials, such as nickel alloy, copper alloy and plastic. The choice of material depends on factors such as the environmental conditions of the container, working pressure and temperature, as well as the requirements for corrosion resistance, strength and weight.
