OUR PRODUCTS AND CAPABILITIES

Yes. Stainless steel tank fabrication is one of Savannah Tank’s core capabilities. We manufacture custom stainless steel storage and process tanks for chemical processing, industrial manufacturing, water treatment, food and beverage, pharmaceutical and other applications.

Common materials include 304 and 316 stainless steel, along with other grades and corrosion-resistant alloys when required by the application. Tanks can be customized with heating or cooling jackets, internal coils, agitator supports, baffles, insulation supports, ladders, platforms, instrumentation connections, specialty nozzles and other features.

Depending on the application, Savannah Tank can also provide polished internal or external surfaces and other specialty finishes. Our engineering and fabrication teams work with customers to select materials, finishes and design features appropriate for the product being stored or processed.

The primary difference is the internal pressure the equipment is designed to withstand and the codes and standards that govern its design.

Atmospheric storage tanks typically operate at or near atmospheric pressure and are commonly used to store water, chemicals, oils, other liquids, or bulk solids such as powders, granules, or pellets. Depending on the application and tank configuration, they may be designed and fabricated to standards such as API 650, API 620, or other applicable specifications.

Pressure vessels, by comparison, are designed to safely contain liquids or gases at pressures significantly above or below atmospheric pressure. In the United States, many industrial pressure vessels are designed and fabricated in accordance with ASME Section VIII, Division 1.

The correct choice depends on the process conditions, including operating and design pressure, temperature, contents, and applicable code requirements. Savannah Tank can help you evaluate those requirements and determine the appropriate design basis for a new tank or vessel.

Both. Savannah Tank manufactures custom tanks, pressure vessels and process equipment at our facilities in Savannah, Georgia, and Ahmedabad, India.

Our U.S. facility supports customers across a broad range of industrial applications and has decades of experience manufacturing custom storage tanks, pressure vessels and other fabricated process equipment. Our India operation expands our manufacturing capacity and provides additional capabilities, including shell-and-tube heat exchangers, polished stainless steel equipment and modular process systems.

Both operations are supported by Savannah Tank’s engineering and quality systems, and both maintain ASME-certified pressure vessel manufacturing capabilities. We work with each customer to determine the most appropriate manufacturing location based on the project’s technical requirements, schedule, economics and final destination.

Savannah Tank’s India operation is an integral part of our company, not simply an outside supplier or subcontract fabricator. Our goal is to provide customers with the same Savannah Tank commitment to engineering, workmanship, inspection, and responsive service regardless of where their equipment is manufactured.

Our India facility maintains ASME-certified pressure vessel manufacturing capabilities and operates under Savannah Tank’s established quality-control system. Our QC personnel maintain material traceability and required fabrication documentation, perform in-process and final inspections, coordinate required NDE, and oversee pressure testing and other project-specific inspection requirements. Qualified welding procedures and personnel are maintained in accordance with the applicable Code and project requirements.

For ASME-stamped pressure vessels manufactured in India, Savannah Tank’s internal QC process is supplemented by the same Code-required Authorized Inspector process that applies to our U.S.-built ASME vessels. The AI performs the required fabrication inspections, reviews the Code documentation, and witnesses the final required pressure test before the vessel is stamped and released.

Customers are also welcome to visit our India facility during fabrication or send their own designated third-party inspectors. Project-specific inspection and testing requirements can be incorporated into the manufacturing plan and documented as required.

For customers considering international fabrication, we are happy to discuss the manufacturing and quality-control process in detail before an order is placed.

Yes. Savannah Tank designs and manufactures welded storage tanks for applications requiring API 650 construction.

API 650 is widely used for welded tanks designed for the storage of petroleum products, chemicals, water, process fluids, and bulk solids such as powders, granules, and pellets at or near atmospheric pressure. Savannah Tank can provide the engineering, fabrication, inspection, and testing required for custom API 650 storage tanks based on the customer’s capacity, material, design conditions, and site requirements.

Because tank diameter can significantly affect transportation and installation, we can also help customers evaluate whether a tank should be completely shop fabricated or designed for field assembly. For larger API 650 tanks, Savannah Tank can engineer the vessel and manufacture a prefabricated tank kit for assembly and welding at the customer’s site.

Savannah Tank fabricates steel tanks, ASME pressure vessels, heat exchangers, and other process equipment in a broad range of customer-specified materials.

Our most common materials include carbon steel and 304 and 316 stainless steel. We can also fabricate custom stainless steel tanks and pressure equipment using duplex stainless steels and other corrosion-resistant alloys when specified for the application.

The appropriate material should be selected by you or your process engineer based on chemical compatibility, corrosion environment, and other application-specific requirements. Once suitable material alternatives have been identified, our engineering and estimating teams can help you compare practical and commercial factors such as material availability, fabrication and welding requirements, relative cost and potential effects on project schedule.

If you are evaluating two or more acceptable materials, send us the alternatives you are considering. We can help you understand how each choice may affect fabrication, price, and delivery.

Yes. Savannah Tank can accommodate a broad range of customer-defined inspection, testing and Factory Acceptance Test (FAT) requirements at both our U.S. and India manufacturing facilities.

Savannah Tank’s own QC team manages the day-to-day inspection and documentation of our fabrication. This includes maintaining material traceability and fabrication records, performing in-process and final inspections, coordinating required NDE, and overseeing hydrostatic or other applicable pressure testing. For ASME-stamped pressure vessels, our internal QC process is supplemented by Code-required independent inspection by an Authorized Inspector (AI). The AI performs required inspections during fabrication, reviews the applicable quality-control documentation—including Code calculations, MTRs, weld maps, welding procedures and inspection records—and witnesses the final required pressure test before the vessel is stamped and released. This Code inspection is separate from any additional customer or customer-appointed third-party inspection.

Depending on the equipment, applicable Code and customer specifications, inspection and testing can also include hydrostatic or other pressure testing and a variety of nondestructive examination (NDE) methods. Available methods include liquid penetrant testing (PT), radiographic testing (RT), ultrasonic testing (UT), magnetic particle testing (MT), positive material identification (PMI), ferrite testing and vacuum-box testing, among others.

Customers are always welcome to visit our facilities to inspect their equipment during fabrication or witness final testing, and we can accommodate customer-appointed third-party inspectors, witness points and hold points when required. If your project has special inspection, testing, or documentation requirements, send us the specification early so we can incorporate those requirements into the quotation, manufacturing plan, and schedule.

Lead times for custom-fabricated tanks and pressure vessels vary considerably from project to project. Factors include the number of vessels required, equipment size and complexity, materials of construction, raw-material availability, our production backlog at the time, and the customer’s required delivery schedule.

A relatively simple storage tank, for example, may require considerably less fabrication time than a large jacketed reactor or other complex pressure vessel. Customer drawing review and approval schedules can also affect the overall project timeline.

For all these reasons, we encourage you to contact us directly to discuss your project and required delivery dates. We include projected lead times and/or a proposed delivery schedule in our quotations so you’ll understand the expected schedule before placing an order.

Yes. Savannah Tank’s manufacturing facility in India is qualified to manufacture pressure equipment for European applications in accordance with the European Pressure Equipment Directive (PED) 2014/68/EU. In fact, we recently built a number of complex pressure vessels for a customer in Austria.

For projects destined for the United Kingdom, our India facility can also manufacture pressure vessels designed to PD 5500 requirements.

Because certification, testing, and documentation requirements vary by country, equipment category, and application, we recommend discussing European or UK projects with our engineering team early in the project. We can review the applicable design and compliance requirements and determine the appropriate manufacturing and inspection approach before fabrication begins.

Yes. Replacement and reverse-engineered tanks and pressure vessels are a common part of Savannah Tank’s work, including equipment that has been operating for several decades.

In many cases, a customer provides us with the original fabrication drawing for a tank or vessel built 40 or 50 years ago. We review the existing design, confirm the current operating and design conditions, perform new engineering and code calculations as required, and design the replacement equipment to current applicable standards.

We understand that original drawings are not always available. In those situations, we can often begin with some pictures, field measurements, and information about the existing process. Our engineering team will work with you to establish the necessary design and operating conditions and develop a replacement vessel that will perform the required function and fit the existing installation.

This approach can be particularly valuable for facilities replacing aging equipment where the original manufacturer, drawings, or engineering records are no longer available.

Savannah Tank can shop-fabricate tanks up to approximately 17 feet in diameter at our U.S. facility, but transportation, rather than manufacturing capability, often determines the practical size limit for a one-piece tank.

Once a large-diameter tank is loaded onto a trailer, overall shipping height can approach 20 feet. At those heights, utility lines, bridges, overpasses, route restrictions, police escorts, and specialized transportation requirements can make freight extremely expensive or, in some cases, make delivery to the site physically impossible. For this reason, a diameter of 14’ to 15’ is often a more practical upper range for tanks shipped in one piece, although Savannah Tank has manufactured larger shop-built vessels when the delivery route allows it. Vessel lengths of 50 to 60 feet are generally much less restrictive, so we try to balance the dimensions of these large tanks to minimize the overall project cost, including the cost of shipping.

For tanks that are too large to ship economically, we can design and engineer the complete tank and fabricate it as a “tank kit” for field assembly. We work with experienced field-fabrication contractors who assemble and weld the tank at the customer’s site.

This approach allows us to support much larger storage-tank projects, including field-erected tanks in the 30- to 40-foot-diameter range and beyond, depending on project requirements.

We do both.

Some customers come to Savannah Tank with complete fabrication drawings and specifications. Others begin with little more than a required capacity, process conditions, material preference, and a general description of what the equipment needs to accomplish.

Savannah Tank’s engineering team can develop custom tank and pressure-vessel designs based on the customer’s requirements, including applicable code calculations, fabrication drawings and 3D models. We can also review customer-developed designs for manufacturability and identify opportunities to simplify fabrication, improve functionality or reduce cost.

This engineering support often begins during the quotation stage, before a purchase order has been issued. We routinely work through multiple design and quotation iterations as customers refine their project requirements and make technical and commercial decisions.

Savannah Tank maintains the certifications, qualified welding procedures, and quality-control systems required to manufacture custom industrial tanks and pressure vessels for a wide range of applications.

Our pressure-vessel manufacturing capabilities include ASME Section VIII, Division 1 construction, supported by qualified welding procedures and welders in accordance with applicable ASME requirements. Savannah Tank also manufactures welded storage tanks to API 650 and API 620 requirements.

Welding procedures, inspection requirements, and quality documentation are determined by the applicable construction code, material, and customer specification. Depending on the project, Savannah Tank can also accommodate customer-specific inspection plans, third-party inspection, nondestructive examination, and other testing requirements.

If a project has unusual materials, welding requirements, inspection criteria, or customer specifications, our engineering and quality teams can review those requirements during the quotation process and confirm the appropriate manufacturing approach.
