Welded Steel Tanks

Common Uses for Welded Steel Tanks

Welded steel tanks are widely used across critical infrastructure and industrial facilities, including:

• Fire protection water storage (fire water tanks and suction supply systems)

• Potable and service water storage (utility reserve and distribution support)

• Condensate and boiler/steam support tanks (where applicable)

• Fuel and oil storage (diesel, fuel oil, lube oil systems project dependent)

• Process storage and industrial liquids (compatibility and spec dependent)

• Environmental compliance systems with secondary containment and spill control

Why Facilities Choose Welded Steel Tanks

1) Strength and structural integrity

Welded construction provides a rigid vessel that performs well under industrial operating conditions and long-term loading.

2) Long service life with proper corrosion protection

With the right coating system and maintenance routine, welded steel tanks can deliver excellent lifecycle value.

3) Customization for site-specific needs

Welded tanks can be built or modified with customized nozzles, manways, vents, overflows, ladders, platforms, and access features.

4) Suitable for large-capacity storage

Welded steel is often selected for higher-capacity storage where long-term stability and durability are top priorities.

Key Design and Installation Considerations

Foundation and drainage are reliability-critical

Settlement or poor drainage can distort tanks, stress connections, and accelerate corrosion at bases, anchors, and support points. A strong project plan includes:

• Stable, level foundation/pad readiness

• Drainage that prevents standing water around the tank base

• Protection of anchors and nearby steel from moisture exposure

Corrosion protection and coatings

Corrosion is one of the biggest long-term risks for welded steel tanks especially outdoors or in wet/chemical environments. Common protection strategies include:

• External coating systems for weather exposure

• Internal linings/coatings based on stored product and service conditions

• Corrosion protection for platforms, supports, ladders, and surrounding steel

Nozzle loads and piping fit-up

Poor alignment or excessive piping loads can create long-term stress at nozzles and penetrations. Precision setting and fit-up reduce:

• Leak risk at connections

• Premature fatigue or cracking

• Rework during commissioning and startup

Safe access and maintainability

Inspection and maintenance are easier (and safer) when access is built in:

• Platforms, ladders, handrails, and work clearances

• Clear labeling and organized piping routes

• Space for inspection, coating work, and repairs

Secondary containment and spill control (when applicable)

For fuels, oils, and certain chemicals, welded tank projects often include:

• Concrete secondary containment (curbing/berms)

• Crack and joint sealing for containment integrity

• Coatings/liners to improve chemical or hydrocarbon resistance

• Controlled drainage and collection strategy

Common Welded Steel Tank Project Types

New tank installation or replacement

Typical scope includes:

• Foundation/pad readiness support

• Tank setting and anchoring

• Tie-ins to pumps, distribution, or process systems

• Access improvements and corrosion protection upgrades

Repairs and rehabilitation

Repair scopes often target:

• Leaks at seams, nozzles, and penetrations

• Corrosion damage and coating failures

• Settlement-related fit-up and support problems

• Upgrades to improve maintainability and inspection readiness

Coatings, linings, and corrosion-control programs

Proactive protection reduces lifecycle cost and unplanned downtime:

• Surface preparation and coating application

• Targeted repairs of high-risk zones (bases, seams, splash zones)

• Preservation of platforms, anchors, and surrounding infrastructure

Outage and shutdown tie-ins

Some modifications and cutovers must be completed in planned windows especially when tied into critical systems.

How Bunney’s Inc. Supports Welded Steel Tank Projects

Welded steel tank work demands safe execution, heavy handling capability, and disciplined fit-up especially in active industrial facilities. Bunney’s Inc. supports welded steel tank projects with:

Best Practices for Long-Term Welded Tank Reliability

Facilities typically get better results when they:

1. Treat foundations and drainage as a core reliability scope

2. Maintain coatings and corrosion protection before degradation spreads

3. Prioritize seams, penetrations, and splash zones for inspection and repairs

4. Control nozzle loads through proper fit-up and pipe support strategy

5. Plan upgrades around outage windows to reduce operational risk
