Pressure Vessels: Custom Manufacturing for Boilers &
General Industry
Rajinder Welding & Mechanical Work, in association with Vikas & Naseer Sons LLP,
Goa, brings over three decades of excellence in pressure part fabrication. Under the leadership
of Mr. Rajinder Kumar Rana, we have established ourselves as a premier Manufacturer of Pressure
Vessels for the boiler industry and various process industries across India.
Leveraging our deep expertise in boiler pressure parts and IBR-compliant
fabrication, we design and manufacture high-integrity pressure vessels that meet the most
demanding industrial requirements. From Steam Accumulators to custom process vessels, we deliver
solutions that ensure safety, reliability, and long service life.
Our Pressure Vessel Manufacturing Expertise
Pressure vessels are critical components that store gases or liquids at
pressures substantially different from the ambient pressure. Our manufacturing process adheres
to the highest international codes and standards, ensuring every vessel we produce is safe,
durable, and fit for purpose.

Specialized Pressure Vessels We Manufacture
1. Steam Accumulators
Steam accumulators are essential for balancing fluctuating steam demand in
industrial plants. They store surplus steam during low demand and release it during peak demand,
ensuring stable boiler operation and optimal energy efficiency.
Our Steam Accumulators Feature:
- Design: Horizontal or vertical cylindrical vessels designed for maximum energy
storage.
- Construction: Heavy-duty plates (typically SA516 Gr.70) with reinforced dished ends.
- Internals: Custom-designed steam distribution and extraction pipes to prevent water
carryover.
- Nozzles: Strategically placed inlet/outlet connections, manholes, and instrument
connections.
- Applications: Sugar mills, paper plants, textile processing, and any industry with
variable steam demand.
Benefits:
- Stabilizes boiler operation under fluctuating loads.
- Reduces boiler cycling, extending boiler life.
- Improves overall plant energy efficiency.
- Improves overall plant energy efficiency.
2. Boiler Mounted Pressure Vessels
As boiler pressure parts specialists, we manufacture various pressure vessels
that are integral to boiler systems:
- Steam Separators & Moisture Separators: Remove moisture from steam to ensure dry,
high-quality steam for processes and turbines.
- Blow-down Vessels: Safely receive and cool boiler blow-down water before disposal.
- Flash Tanks: Recover flash steam from high-pressure condensate for use in
low-pressure applications.
- Air Receivers: Store compressed air for instrument air and utility applications in
power plants.
3. Process Pressure Vessels for General
Industry
Beyond boilers, we serve various industries with custom pressure vessels:
- Chemical Industry: Reactors, storage vessels, and separation columns for chemical
processes.
- Oil & Gas: Knock-out drums, filters, and surge vessels.
- Pharmaceutical Industry: High-purity SS vessels for sterile processes.
- Food Processing: Jacketed vessels for heating/cooling of food products.
- Fertilizer Plants: Ammonia receivers and process vessels.
4. Heat Exchangers & Coils
Our Manufacturing Process
1. Design &
Engineering

- Shell assembly with precise alignment.
- Nozzle cutting, fitting, and welding.
4. Welding
- Certified welders for all position welding.
- Qualified Welding Procedure Specifications (WPS) for all material joints.
- Processes: SAW, GTAW (TIG), SMAW (Arc), GMAW (MIG).
5. Testing &
Inspection
- Non-Destructive Testing (NDT): Radiography (RT), Ultrasonic (UT), Dye Penetrant
(DPT), Magnetic Particle (MPT) as per code requirements.
- Hydrostatic Testing: Pressure testing to 1.3 to 1.5 times the design pressure.
- Pneumatic Testing: Where required for specific applications.
6. Finishing &
Dispatch
- Surface preparation and painting as per customer specification.
- Insulation where required.
- Safe transportation to site, including heavy lift coordination.
