What Is Meant by the Term Pressure Vessels?

The term pressure enclosed vessel refers to equipment used across industries such as food processing, oil and gas, petrochemical, chemical and food processing. There are several key types of pressure vessel connections commonly used in various industries.

Common Types of Pressure Vessel Connections

The common types of ASME pressure vessel connections include:

  1. Long Weld Necks – Long weld necks are a connection type known for being economical and light. They are ideal for use in situations where there is a minimum requirement for reinforcing areas.
  2. Q Lip Nozzles – The Q lip nozzle is a unique pressure vessel connection designed with an insert lip. The Q lip nozzle is welded directly into the vessel wall (shell or head), providing full reinforcement to the area where the hole has been but out.
  3. Stub End Nozzles – This type of connection does not have a flange termination. It is configured with a butt weld stub end. This connection can be provided flat, contoured, and with a Q-lip on the bottom.
  4. Studding Outlets – Studding outlets are utilized for the unique and compact design that they provide. They are ideal for use by pressure vessel fabricators that want to save on the amount of outside projection.
  5. Large Diameter Flanges – Large diameter flanges are another major type of pressure vessel connection used in industry. Forged Components can manufacture them to any customer specifications.
