Supply high quality export spherical head ASME B16.9 16 manganese hemispherical head spherical crown head​


PRODUCT DETELS

  1. Spherical Head:

    • A spherical head refers to a component used in pressure vessels or tanks that has a shape similar to a sphere.
    • The spherical shape allows for even distribution of stress and pressure, making it suitable for high-pressure applications.
    • These heads are typically used in conjunction with cylindrical or spherical vessels.
  2. ASME B16.9:

    • ASME B16.9 is a standard published by the American Society of Mechanical Engineers (ASME) that specifies factory-made wrought steel buttwelding fittings.
    • It covers various types of fittings, including elbows, tees, reducers, caps, and others.
    • While ASME B16.9 primarily focuses on fittings, it does not specifically cover spherical heads.
  3. 16 Manganese Hemispherical Head:

    • A 16 manganese hemispherical head refers to a hemispherical head made of a specific grade of steel known as 16Mn (16 manganese).
    • 16Mn steel is a low alloy high-strength structural steel commonly used in pressure vessel applications.
    • Hemispherical heads have a shape similar to a half-sphere, providing improved stress distribution and pressure resistance.
  4. Spherical Crown Head:

    • A spherical crown head combines the properties of a spherical shape and a crown shape.
    • It is commonly used in pressure vessels where additional strength and stress distribution are required.
    • The spherical crown shape provides better resistance to internal pressure compared to other head shapes.

When working with spherical heads, it is crucial to consider the specific requirements of your application. This includes factors such as material selection, dimensions, wall thickness, pressure rating, and compliance with relevant codes and standards, such as ASME Boiler and Pressure Vessel Code (BPVC).

It is recommended to consult with qualified engineers or pressure vessel specialists who can provide guidance on selecting the appropriate head type, material, and ensure compliance with the necessary regulations and standards. Additionally, working with reputable manufacturers or fabricators experienced in producing spherical heads can help ensure the desired quality and performance of the components.
