Pressure equipment refers to a variety of equipment and systems that are designed to contain, store, transport, or process fluids or gases at pressures higher than atmospheric pressure. These equipment is designed to ensure the safety and integrity of the contained substances under high pressure. 

1. Pressure Vessels: 

A pressure vessel is defined as a container with a pressure differential between inside and outside. The inside pressure is usually higher than the outside, except for some isolated situations. The fluid inside the vessel may undergo a change in state as in the case of steam boilers, or may combine with other reagents as in the case of a chemical reactor.

Pressure vessels often have a combination of high pressures together with high temperatures, and in some cases flammable fluids or highly radioactive materials.

Pressure vessels are used in a number of industries; for example, the power generation industry for fossil and nuclear power, the petrochemical industry for storing and processing crude petroleum oil in tank farms as well as storing gasoline in service stations, and the chemical industry (in chemical reactors) to name but a few.

The size and geometric form of pressure vessels vary greatly from the large cylindrical vessels used for high-pressure gas storage to the small size used as hydraulic units for aircraft. Some are buried in the ground or deep in the ocean, but most are positioned on ground or supported in platforms. 

Pressure vessels are usually spherical or cylindrical, with domed ends. The cylindrical vessels are generally preferred, since they present simpler manufacturing problems and make better use of the available space.

Spherical vessels have the advantage of requiring thinner walls for a given pressure and diameter than the equivalent cylinder. Therefore they are used for large gas or liquid containers, gas-cooled nuclear reactors, containment buildings for nuclear plant, and so on

2. Boilers: 

Boilers are a type of pressure equipment used to generate steam for heating or power generation. They are commonly found in power plants, industrial facilities, and residential heating systems.

Boilers can be characterized by the arrangement of heat transfer surfaces – either fire tube or water tube – and by the combustion system. The appropriate arrangement is determined by suitable fuel, steam conditions and capacity

3. Heat Exchangers:

Heat exchangers are pressure equipment used to transfer heat between two or more fluids. They typically consist of the following components:

a. Tubes or Tubesheets: Fluid flows through tubes, while another fluid flows over the tubesheets to exchange heat.

b. Shell: The outer casing that contains the tubes and fluid.

c. Baffles: Internal components that direct the flow of fluid and enhance heat transfer.

d. Inlet and Outlet Connections: For the entry and exit of the heat exchange fluids.

4. Pressure Piping: 

Piping components intended for the transport of fluids when connected together for integration into a pressure system. Piping includes a pipe or system of pipes, pipe spools, tubing, fittings, expansion joints, hoses, or other pressure bearing components as appropriate. Pressure piping systems transport fluids under pressure. Components of pressure piping include:

a. Pipes: The main conduits for fluid transport.

b. Fittings: Connectors, elbows, and tees that join pipes together.

c. Valves: Used to control and regulate the flow of fluids.

d. Flanges: Connect pipes to other components like valves, pumps, or tanks.
