Separating Gunbarrel Tanks Based on Customer Specific Needs

In oil and gas production, water handling, and fluid separation operations, one size rarely fits all. Site conditions, production volumes, fluid characteristics, emissions goals, and transportation limitations can all change what type of separation equipment works best. That is why separating gunbarrel tanks based on customer specific needs is such an important strategy for operators who want reliable performance and long service life.

At Smith Industries, gunbarrel tanks are built with practical field experience in mind. Standard designs offer proven performance, while custom engineering options help clients match tank specifications to real operating demands. From API-compliant storage tank builds to delivery and placement support, Smith Industries provides customers with separation equipment designed around production goals rather than forcing operations to adapt to standard equipment limitations.

What Is a Gunbarrel Tank?

A gunbarrel tank is a gravity separation vessel commonly used in upstream oil and gas operations. These tanks are designed to separate oil, water, gas, and solids after production fluids come from the well stream. Separation happens through retention time, internal flow control, and gravity differences between fluids.

Gunbarrel tanks are commonly used to:

• Separate produced water from oil

• Allow gas breakout before downstream handling

• Settle solids and sediment

• Improve fluid quality before storage or transfer

• Reduce strain on downstream treating equipment

The concept remains valuable because it is simple, dependable, and effective when properly sized and configured.

According to American Petroleum Institute standards, storage tank design and fabrication play a major role in safe fluid handling operations across the energy industry. Smith Industries builds tanks to API 12F and API 12D specifications depending on project requirements.

Why Customer Specific Design Matters

No two production sites are exactly alike. A tank that performs well in one basin may need modifications in another due to fluid chemistry, temperature swings, sand loading, or flow rates.

That is why separating gunbarrel tanks based on customer specific needs creates better long-term value. Instead of retrofitting field operations around standard equipment, the tank can be built to support actual production conditions.

Examples of customer-driven requirements include:

• Higher or lower barrel capacity

• Modified inlet designs

• Alternate outlet nozzle arrangements

• Enhanced internal separation components

• Specialized coatings or linings

• Transportation-friendly dimensions 

• Monogrammed or non-monogrammed builds

• Site-specific lifting or installation features

Smith Industries works with customers to review these factors and build a tank configuration that aligns with project needs.

Standard Smith Industries Gunbarrel Tank Features

Smith Industries standard design gunbarrel tanks are backed by years of field-proven experience. These tanks are available in API configurations of:

• 750 barrel tanks

• 1000 barrel tanks

Standard design features include:

• Removable flume and gas boot assembly

• Flat spreader table for added separation benefits

• 4-inch API 5L threaded couplings

• 8-inch ANSI raised face slip-on flanges for waterleg outlet connections

These features support operational efficiency while maintaining a rugged design suited for demanding environments.

Expanded Capacity Options for Growing Operations

Some operations need more flexibility than standard sizes alone. Smith Industries currently builds the following tank capacities:

• 500 BBL

• 750 BBL

• 1000 BBL

• 1150 BBL

This range allows operators to choose equipment based on throughput expectations, pad layout, trucking logistics, and future growth planning.

For lower-volume sites, a 500 BBL unit may be the right fit. For busier locations or centralized operations, 1000 or 1150 BBL tanks can provide added retention time and operational capacity.

Choosing the right capacity is one of the most important steps in separating gunbarrel tanks based on customer specific needs because undersized equipment can reduce efficiency, while oversized equipment may increase unnecessary costs.

Surface Preparation and Coating Quality

Tank performance is not only about steel fabrication. Surface preparation and coatings also affect long-term durability, corrosion resistance, and maintenance intervals.

Smith Industries blasts tanks indoors with steel shot to prepare surfaces for:

• Exterior paint systems

• Internal coatings or linings

The company also operates two indoor coat and paint shops that are temperature controlled to support proper application and cure times.

This controlled process can improve coating consistency compared with outdoor painting environments exposed to weather, dust, or temperature swings.

According to National Association of Corrosion Engineers, proper coating preparation and application are key contributors to corrosion prevention and equipment longevity across industrial assets.

Monogrammed vs Non-Monogrammed Tanks

Some customers require tanks built under certified code programs, while others need practical field storage solutions without monogram requirements. Smith Industries offers both monogrammed and non-monogrammed options depending on project specifications.

This flexibility helps customers meet:

• Owner standards

• Regulatory expectations

• Insurance requirements

• Budget goals

• Operational timelines

By offering both pathways, Smith Industries helps clients avoid paying for specifications they do not need while still supporting higher-code applications when required.

Delivery and Tank Setting Support

Fabrication is only part of the job. Field delivery and placement also matter.

Smith Industries can deliver and set tanks using knuckleboom trucks, helping simplify logistics for customers who want a smoother handoff from manufacturing to installation.

Benefits include:

• Reduced coordination between vendors

• Faster deployment timelines

• Controlled unloading and placement

• Less dependence on separate crane scheduling

• Streamlined project execution

For many customers, this single-source support adds value by reducing delays and communication gaps.

How Smith Industries Helps Customers Choose the Right Tank

When reviewing separating gunbarrel tanks based on customer specific needs, Smith Industries can help evaluate:

Production Factors

• Daily fluid volume

• Oil/water ratio

• Gas breakout levels

• Sand or solids content

Site Factors

• Available footprint

• Access roads

• Transportation restrictions

• Climate exposure

Business Factors

• Budget targets

• Maintenance preferences

• Delivery schedules

• Future expansion plans

By reviewing these categories early, customers can make smarter purchasing decisions and avoid equipment mismatches later.

Why Experience Still Matters

Gunbarrel tanks are proven equipment, but successful results depend on proper fabrication and smart configuration. Smith Industries combines traditional tank knowledge with practical customization options so customers receive equipment that works in real field conditions.

That combination of proven standards and flexible execution is why operators continue to trust experienced manufacturers when separation performance matters.

Final Thoughts on Separating Gunbarrel Tanks Based on Customer Specific Needs

Every operation has different production demands, space limitations, and compliance expectations. That is why separating gunbarrel tanks based on customer specific needs remains the smartest path for many operators.

Smith Industries provides standard API-based gunbarrel tank designs along with custom solutions built around real-world customer requirements. With multiple capacity options, quality coating processes, monogram flexibility, and delivery support, Smith Industries helps clients secure tanks built for performance, durability, and efficiency.

When the right tank is matched to the right application, operations run smoother, maintenance becomes easier, and long-term value improves.
