Pressure Vessel

Pressure vessels can be categorized into refrigeration and chemical pressure vessels. A refrigeration pressure vessel usually comprises of six components, namely, cylinder, head, flange, sealing element, opening and nozzle, and support. Similarly, a chemical pressure vessel typically consists of cylinder, head, flange, sealing element, opening and nozzle, and support.

Pressure vessels have wide-ranging applications across different sectors of the economy such as petrochemical, energy, scientific, military, and others. They are equipped with safety devices, inner parts, and metering devices to achieve diverse production processes. Thus, pressure vessels are vital components for maintaining the smooth operation of various industries.

Cost-Effective: Pressure vessels have lower operating costs and require less frequent maintenance, making them a cost-effective option for industries that use them.


Durability: Pressure vessels are constructed from highly durable materials, ensuring that they last long and reliably perform their intended functions.


Customized Design: Pressure vessels can be customized to meet specific industrial requirements, ensuring that they meet the unique needs of individual clients.


High Efficiency: Pressure vessels are designed to operate at high levels of efficiency, ensuring that they do not waste resources or incur unnecessary costs.


Versatility: Pressure vessels can be used in a wide range of industries, from chemical processing to petroleum refining, making them a versatile and adaptable solution to many industrial requirements.


Reduced Transport Costs: Pressure vessels can hold large quantities of materials in a single location, reducing the frequency of transport and associated costs.


Scalability: Pressure vessels can be easily scaled up or down to accommodate changes in production or transport volumes, making them ideal for businesses with fluctuating demand.


Regulatory Compliance: Many industries require strict adherence to safety regulations, and pressure vessels are designed to meet these safety requirements, ensuring that businesses remain compliant with relevant regulations.

Application of Pressure Vessel

Refrigeration Pressure Vessels

Primarily utilized in refrigeration systems that use ammonia as their refrigerant medium, pressure vessels are also employed for refrigerant storage, separation, heat exchange, and other related process systems.

Chemical Pressure Vessels

Pressure vessels are primarily utilized for storage and transportation of medium to low pressure gases and liquids, separation and reaction processes, and various heat exchange equipment in several industries such as chemical fertilizer, coal chemical, salt chemical, polysilicon, petrochemical, and refining. They find extensive usage in fields such as petroleum, chemical industry, metallurgy, light industry, and medicine.
