LPG Storage Tank Manufacturers in India

As experienced LPG storage tank manufacturers in India, Anpam Engineering provides engineered storage vessels for applications where LPG must be safely contained under pressure.

LPG storage tanks are pressure vessels, and their design must account for the mechanical and thermal conditions expected during filling, storage, withdrawal, and operating cycles. ASME Section VIII Division 1 covers requirements for the design, fabrication, inspection, testing, and certification of pressure vessels operating at internal or external pressures exceeding 15 psig.

Depending on the project, important design considerations can include:

• LPG storage capacity
• Design pressure
• Operating pressure
• Design temperature
• Operating temperature
• LPG composition and service conditions
• Corrosion allowance
• Vessel orientation
• Shell and head configuration
• Nozzle arrangement
• Pressure-relief requirements
• Support arrangement
• Inspection requirements
• Applicable statutory regulations

The final design should always be established by qualified engineers against the applicable project specifications and regulatory requirements.

What Is an LPG Storage Tank?

An LPG storage tank is a pressure vessel designed to store liquefied petroleum gas under controlled pressure and temperature conditions.

Unlike a conventional atmospheric storage tank, LPG is normally maintained in a pressurized liquid-vapour system. The vessel therefore needs suitable mechanical strength and engineered safety features.

Industrial LPG storage systems can include:

• Storage vessel
• Filling connections
• Liquid withdrawal connections
• Vapour connections
• Pressure-relief devices
• Level indication
• Pressure indication
• Drain arrangements
• Isolation valves
• Earthing and other site-safety provisions

The precise arrangement depends on the tank design, storage facility, site layout, regulatory requirements, and customer specifications.

For this reason, purchasing an LPG vessel based solely on volume is not sufficient. The pressure rating, applicable design standard, installation requirements, and statutory approvals also need to be considered.

Customized LPG Tanks for Industrial Requirements

Different industries have different LPG consumption patterns. A small commercial installation may require a comparatively compact vessel, while a manufacturing facility, process plant, or large fuel installation may require substantially greater storage capacity.

Anpam Engineering can develop LPG tanks according to application-specific requirements.

Customization may involve:

• Horizontal or vertical configuration, where permitted by the applicable design and installation requirements
• Storage capacity
• Shell diameter
• Vessel length
• Design pressure
• Design temperature
• Material specification
• Nozzle orientation
• Valve connections
• Manway arrangement
• Support configuration
• Lifting arrangements
• Surface preparation and coating
• Inspection and documentation requirements

The appropriate configuration should be finalized after evaluating the site, operating conditions, applicable regulations, and project drawings.

Types of LPG Storage Tanks

Horizontal LPG Storage Tanks

Horizontal pressure vessels are widely used for bulk LPG storage installations where the site layout allows a horizontal vessel arrangement.

They can be designed with saddle supports, nozzles, valves, instruments, and other accessories according to project requirements.

Vertical LPG Storage Tanks

Vertical configurations can be considered for applications where the available site footprint, storage arrangement, or engineering design calls for a vertical vessel.

The choice between horizontal and vertical arrangements depends on the installation, capacity, site constraints, and applicable requirements.

Above-Ground LPG Storage Tanks

Above-ground storage can be used when the facility layout and applicable safety regulations permit the arrangement.

The tank installation requires appropriate separation distances, foundations, access, protection, and safety systems as determined by the relevant authorities and project design.

Customized LPG Pressure Vessels

Some projects require special dimensions, material grades, pressure ratings, connection arrangements, or site-specific configurations. These requirements can be incorporated into a custom pressure-vessel design.

LPG Storage Tank Design Considerations

Designing an LPG storage vessel requires consideration of several interdependent parameters.

1. Storage Capacity

The required storage volume should be established from LPG consumption, delivery frequency, operating philosophy, and planned storage inventory.

2. Design Pressure

The vessel’s design pressure must be established from the applicable design basis and LPG service conditions.

3. Design Temperature

The design temperature should account for expected operating conditions and relevant environmental or process considerations.

4. Material Selection

The shell, heads, nozzles, supports, and other components should use materials suitable for the specified service conditions.

5. Corrosion Allowance

Where applicable, an appropriate corrosion allowance may be incorporated into the mechanical design based on the service environment and project requirements.

6. Nozzle Arrangement

Filling, vapour, liquid withdrawal, drain, instrumentation, and other connections must be positioned appropriately for safe and practical operation.

7. Pressure Relief

Pressure-relief provisions are a critical part of LPG storage system design and should comply with the applicable regulatory and engineering requirements.

8. Supports and Foundations

The vessel support arrangement must account for the tank’s empty, operating, and relevant design loads as well as site conditions.

Materials Used for LPG Storage Vessels

Material selection is an important aspect of pressure-vessel manufacturing.

Depending on the project specification, suitable pressure-vessel materials may include:

• Carbon steel
• Low-temperature carbon steel
• Alloy steel
• Other approved pressure-vessel materials

The material grade should be selected according to design temperature, mechanical properties, service conditions, code requirements, and customer specifications.

Material traceability is also important for pressure-vessel projects. Documentation such as material test certificates may be required as part of the quality and inspection package.

The final material specification should be determined through engineering review rather than selecting a material based only on cost.

ASME Pressure Vessel Manufacturing

Many industrial LPG storage vessels are engineered using recognized pressure-vessel design standards.

ASME Section VIII Division 1 specifies requirements for the design, fabrication, inspection, testing, and certification of pressure vessels operating above 15 psig.

Anpam Engineering’s manufacturing portfolio includes ASME pressure equipment, and its published company information identifies ASME U-Stamp pressure-vessel capability. For a specific LPG project, the applicable certification scope should be confirmed against the vessel design, project specification, and required certification.

This distinction is important: ASME design compliance and statutory approval for LPG storage are not necessarily the same thing. An LPG installation in India may also be subject to applicable requirements administered by the Petroleum and Explosives Safety Organisation (PESO) and other authorities.

PESO currently publishes the Gas Cylinder Rules and related amendments, including amendments issued in 2025 and 2026.

The precise regulatory pathway depends on the LPG storage arrangement and applicable rules.

Safety Considerations for LPG Storage Tanks

LPG storage requires careful attention to both vessel integrity and the surrounding installation.

Important safety considerations include:

Pressure Protection

Suitable pressure-relief arrangements are required to protect the vessel against unacceptable pressure conditions.

Instrumentation

Pressure and level monitoring help operators understand storage conditions and manage the system effectively.

Isolation

Appropriately selected isolation valves and connections facilitate controlled operation and maintenance.

Inspection

The vessel should be inspected and tested according to the applicable code, regulatory requirements, and inspection plan.

Site Layout

Clearances, access, foundations, fire protection, vehicle protection, and other site requirements must be addressed during installation planning.

Earthing and Electrical Safety

Appropriate earthing and hazardous-area considerations should be incorporated into the complete LPG installation where applicable.

These requirements should be established by qualified professionals and the relevant regulatory authorities rather than relying on a generic checklist.

Manufacturing Process for LPG Storage Tanks

A controlled manufacturing process is essential for pressure vessels used in LPG service.

Engineering and Design

The project begins with review of capacity, pressure, temperature, material, dimensions, connections, applicable standards, and customer specifications.

Material Procurement

Approved pressure-vessel materials are procured with appropriate traceability and documentation.

Plate Cutting and Forming

Plates are cut and formed into the required shell and head geometry using controlled fabrication processes.

Welding

Qualified welding procedures and appropriately qualified personnel are used according to the applicable project requirements.

Non-Destructive Examination

Required weld examinations may include radiographic testing, ultrasonic testing, dye penetrant testing, magnetic particle testing, or visual examination, depending on the design and inspection plan.

Pressure Testing

Pressure testing is performed according to the applicable design code and project requirements.

Surface Preparation

Surface preparation and coating systems can be applied according to the intended installation environment.

Final Inspection

Dimensional accuracy, connections, accessories, documentation, and final workmanship are reviewed before dispatch.

Quality Control for LPG Tanks

Quality control is particularly important for pressurized LPG storage because vessel integrity directly affects operational safety.

Depending on the project, quality documentation may include:

• Material test certificates
• Welding procedure documentation
• Welder qualification records
• NDT reports
• Dimensional inspection records
• Pressure-test reports
• Heat-treatment records where applicable
• Inspection certificates
• Nameplate details
• Manufacturing documentation

The exact quality dossier depends on the applicable code, customer specification, inspection agency, and regulatory requirements.

A professional LPG storage tank manufacturer should therefore be able to explain not only how the vessel is fabricated but also how its quality is verified and documented.
