  1. High-Pressure Pressure Vessel Head:

    • The high-pressure pressure vessel head refers to the end closure or cap used in a pressure vessel.
    • In this context, it likely implies a head designed to withstand high internal pressures.
    • The head can have different shapes, such as spherical, elliptical, hemispherical, or cylindrical, depending on the specific vessel design.
  2. Spherical Plugging:

    • Spherical plugging typically refers to a technique used to seal or plug an opening in a vessel using a spherical-shaped plug.
    • The spherical plug is designed to fit precisely into the opening to create a tight seal.
  3. Welded Pipe:

    • A welded pipe is a type of pipe made by joining two or more sections of metal through welding.
    • In the context of pressure vessels, welded pipes are commonly used to connect various components or sections of the vessel.
  4. Spherical Plug:

    • A spherical plug refers to a component shaped like a sphere that is used to seal or plug an opening in a vessel or pipe.
    • The spherical shape allows for a more uniform distribution of stress and pressure.
  5. Hemispherical:

    • Hemispherical refers to a shape that resembles half of a sphere.
    • Hemispherical heads are commonly used in pressure vessels due to their ability to distribute stress more evenly.
  6. Oval:

    • Oval refers to a shape that is elongated and curved, resembling an ellipse.
    • Oval-shaped heads or components can be used in certain pressure vessel designs.
  7. Spherical Crown:

    • Spherical crown refers to a shape that combines the characteristics of a sphere and a crown.
    • Spherical crown heads are used in pressure vessels where additional strength and stress distribution are required.
  8. Welded Carbon Steel:

    • Welded carbon steel refers to pipes or components made from carbon steel that have been joined together using welding methods.
    • Carbon steel is a common material choice due to its strength, durability, and cost-effectiveness.

When dealing with high-pressure pressure vessels, it is important to adhere to relevant codes and standards, such as ASME Boiler and Pressure Vessel Code (BPVC), to ensure the design, fabrication, and welding meet safety requirements.

It is recommended to consult with qualified engineers and follow industry best practices when designing, fabricating, and inspecting pressure vessel heads, pipes, and components to ensure they meet the required standards and safety regulations.
