What Are the Main Application Areas and Uses of Vessel Heads?

Vessel Head End Cap (also known as Vessel end cap) is a mechanical component widely used in various industries, mainly used as the end closure component of pipeline, pressure vessel or other equipment.

What are the main application fields and uses of end caps?

1. Pressure vessel

Vessel head is an important part of pressure vessel, which is used to bear the internal pressure and ensure the sealing of the vessel. Common pressure vessel heads include:

Spherical head: Used for high pressure vessels, with uniform force and high strength.

Oval head: Widely used, better pressure bearing performance, material saving.

Disc shaped head: Used for medium and low pressure vessels, low manufacturing cost.

Flat head: Used for low pressure vessel, simple structure.

2. Piping system

Vessel head is used to close the end of pipeline in pipeline system. Common uses include:

Sealing of pipe ends.

As service port closure.

Temporary sealing of pipelines during pressure testing.

3. Storage tanks

Heads are used to close the top or bottom of storage tanks:

Petrochemical storage tanks.

Storage vessels for liquids, gases or granules.

Food grade tanks such as milk tanks.

4. Heat exchanger

Head is an important part in heat exchanger, which is used to close the tube plate and connect with the tube bundle to ensure the distribution and isolation of fluid.

5. Boiler and tube and shell equipment

In boilers and other similar equipment, headers are used to close the boiler end and ensure the airtightness of steam or other media.

6. Construction and decoration

In the field of architecture and decoration, Heads can also be used as part of an artistic design, such as decorative headers for pipes or parapet ends.

7. Other Industry Applications

Aerospace: For fuel tanks or pressure vessels.

Automotive industry: For fuel tanks, compressor vessels.

Pharmaceutical and foodstuffs: end closures for high cleanliness equipment.

Material Selection

According to the usage environment, the material of header can be:

Carbon steel: for general industrial use.

Stainless steel: for corrosive environment or food and medicine industry.

Alloy steel: for high pressure and high temperature occasions.

Manufacturing process

Commonly used manufacturing processes for heads include stamping, spinning and welding, and suitable processes are selected according to different shape and size requirements.

The performance, safety and service life of the equipment can be significantly improved by choosing the appropriate type and material of head.

Vessel heads are used in a number of fields, common ones include:

1.Gas storage tanks: Heads are used on top of gas storage tanks to prevent gas leakage and provide a complete seal to the tank.

2.Pressure Vessels: In pressure vessels, heads are important safety components used to prevent too much or too little pressure inside the vessel.

3.Laboratory equipment: laboratory equipment such as fermenters, bioreactors, etc. require heads to maintain sealing and safety during experiments.

4.Water treatment equipment: water treatment equipment such as sedimentation tanks, filter tanks, etc. Heads are used at the inlet and outlet of the equipment, which can prevent water leakage and pollution.

5.Pipeline system: in pipeline system, head is used to close the end of pipeline, which can prevent debris from entering the pipeline and keep the pipeline sealed.

6.Aerospace field: In aerospace field, heads are used to seal various fluid containers, such as fuel tanks, hydraulic oil tanks, etc., which can ensure the normal operation and safety of aircraft.

7.Automobile field: In the automobile field, heads are used to seal fluid containers such as automobile fuel tanks, which can ensure the normal operation and safety of automobiles.

In a word,Pressure vesselhead is a kind of safety part widely used in various equipments and containers for keeping sealing and preventing leakage.
