Pressure Vessel Manufacturers in  India

Heat Transfer Equipments Pvt Ltd is an experienced U Stamp Pressure Vessel manufacturer in Coimbatore, India, specializing in engineered pressure vessels for demanding industrial applications. We manufacture custom-built vessels based on project requirements, operating conditions, material specifications, design parameters, and applicable engineering standards.

Our pressure vessel manufacturing capabilities cover a wide range of industrial requirements, from process and storage vessels to specialized equipment designed for elevated pressure and temperature service. With a strong focus on engineering accuracy, fabrication quality, inspection, and documentation, we deliver pressure vessels suitable for critical process environments.

As an ASME U Stamp certified manufacturer, we follow applicable requirements of ASME Section VIII for pressure vessel design and fabrication where specified by the project. Each vessel is engineered with attention to pressure containment, material compatibility, welding quality, inspection requirements, and safe operation.

Custom Pressure Vessel Manufacturing

Pressure vessels cannot be designed effectively using a single standard configuration because every industrial process has different operating requirements. Working pressure, design temperature, fluid characteristics, volume, corrosion allowance, nozzle arrangement, support configuration, and installation conditions can all influence the final design.

Our engineering team develops pressure vessels according to individual project specifications. The vessel geometry, shell thickness, head configuration, openings, reinforcement details, supports, and connections are selected based on the intended service and applicable design requirements.

We can manufacture vessels in different configurations, including vertical and horizontal arrangements, depending on process requirements and available plant space.

Types of Pressure Vessels We Manufacture

We manufacture custom-engineered pressure vessels for a variety of industrial applications, including:

• Process pressure vessels
• Storage pressure vessels
• High-pressure vessels
• Chemical process vessels
• Industrial reactors
• Separators and knock-out vessels
• Gas and liquid storage vessels
• Special-purpose pressure vessels
• Custom ASME pressure vessels

The final configuration is developed according to the customer’s process data and engineering requirements rather than relying on a fixed standard design.

Pressure Vessel Design and Engineering

Engineering is one of the most important stages in pressure vessel manufacturing. A vessel must safely withstand internal or external pressure, temperature variations, operating loads, and other forces expected during its service life.

Our design process considers key parameters such as:

• Design pressure and operating pressure
• Design and operating temperature
• Vessel volume and dimensions
• Material selection
• Corrosion allowance
• Shell and head thickness
• Nozzle size and orientation
• Reinforcement requirements
• Support and lifting arrangements
• Internal components where required
• External loads and piping connections

Depending on the project, engineering documentation may include fabrication drawings, nozzle orientation details, material specifications, welding documentation, inspection requirements, and manufacturing records.

Design Pressure and Temperature

The design pressure and design temperature are fundamental parameters in pressure vessel engineering. They define the conditions that the vessel is required to safely withstand during its intended service.

The design should account for the maximum credible pressure and temperature conditions rather than simply the normal operating values. Other factors, including vacuum conditions, pressure fluctuations, fluid characteristics, and external loads, may also need to be evaluated depending on the application.

Correct definition of these parameters helps determine appropriate material grades, wall thicknesses, head dimensions, reinforcement requirements, and testing procedures.

Materials of Construction

Material selection depends on pressure, temperature, process fluid, corrosion characteristics, mechanical requirements, and project specifications.

Depending on the application, pressure vessels can be manufactured using suitable grades of:

• Carbon steel
• Stainless steel
• Low-temperature carbon steel
• Alloy steel
• Other compatible engineering materials as specified by the project

Material traceability is important for pressure-containing equipment. Material certificates and relevant inspection documentation can be maintained as part of the manufacturing quality records.

For corrosive or demanding services, the material selection is evaluated carefully to provide suitable resistance and long-term service performance.

ASME U Stamp Pressure Vessel Manufacturing

For projects requiring ASME certification, our pressure vessel manufacturing follows the applicable requirements of ASME Section VIII and the scope of the certified manufacturing system.

The ASME U Stamp is associated with the manufacture of pressure vessels under the applicable ASME requirements. It provides customers with an important assurance that the vessel manufacturing process is controlled through an established quality system and inspection framework.

For U Stamp projects, design, materials, welding, inspection, testing, documentation, and quality control are handled according to the applicable code requirements and project specifications.

Pressure Vessel Fabrication Process

Quality fabrication starts with proper material preparation and continues through controlled manufacturing stages.

A typical manufacturing process includes:

1. Material identification and inspection
2. Plate cutting and preparation
3. Rolling or forming of shell sections
4. Head forming or procurement
5. Fit-up and dimensional inspection
6. Welding and controlled fabrication
7. Nozzle and reinforcement installation
8. Support and attachment fabrication
9. Non-destructive examination
10. Hydrostatic or specified pressure testing
11. Final dimensional inspection
12. Surface preparation and coating where required
13. Final documentation and dispatch

Each stage is performed with attention to dimensional accuracy, weld quality, traceability, and project-specific requirements.

Welding Quality and Inspection

Welding plays a critical role in pressure vessel integrity. Our fabrication process uses qualified welding procedures and appropriately qualified welding personnel according to applicable project and code requirements.

Welded joints may be examined using appropriate non-destructive testing methods based on the vessel design and inspection requirements.

Depending on the project, inspection can include:

• Visual inspection
• Radiographic testing
• Ultrasonic testing
• Magnetic particle testing
• Liquid penetrant testing
• Dimensional inspection

The inspection scope depends on the applicable code, joint category, design requirements, service conditions, and customer specifications.

Hydrostatic Testing of Pressure Vessels

Pressure testing is an important part of the final quality verification process. Hydrostatic testing can be performed where required to verify the pressure-containing integrity of the completed vessel.

During testing, the vessel is filled with a suitable test medium and pressurized according to the applicable testing requirements. The vessel and its pressure-containing components are inspected for evidence of leakage or other unacceptable conditions.

Testing procedures and acceptance criteria are determined according to the applicable design code and project requirements.

Applications of Pressure Vessels

Our pressure vessels are designed for use across several industrial sectors where controlled containment of gases or liquids is required.
