Sanitary Tanks

Experts in process compliance and custom applications

Distillation Columns

Apache commonly produces complex distillation column projects including add-ons for internal trays, insulation, cladding, ladders, and platforms as well as transport. Our engineers, technicians, and fabricators are experts in working with stainless, AL6XN, Hastelloy, and other high alloy materials.

Evaporators

Apache’s evaporators are fabricated to custom sizes and configurations for a variety of industries. Our expertise, facilities, and equipment have helped our customers get the highest quality single-pass and falling film evaporators in single or multiple quantities.

Mix Tanks

Apache has expertise with agitated vessels including standard props, full sweep, scraper blades, and high sheer rotating. We provide tanks built to customer specifications, with common aspects including sight glasses, lights, rupture discs, spray balls, and controls. Apache also has in-house capabilities for passivation and electropolishing stainless finishes often required for process tanks.

Reactors

Apache has a great deal of expertise in engineering and manufacturing heat exchangers and process reactors. All pieces of equipment are built to customer specifications, from a small lab reactor to a 160 ft. long industrial column reactor.

Our large tank engineers work closely with customers to determine:

  • Structural design
  • Heat transfer analysis
  • Material finish requirements
  • Agitation performance

Sanitary Tanks

Apache has best-in-class processes and expertise in compliance and surface finishes. ASME-certified sanitary tanks manufactured at Apache include:

  • Cook tanks
  • Mixing tanks
  • Heat exchangers
  • Process tanks
  • Storage tanks

Our sanitary tanks are found in the food, beverage, pharmaceutical, biotechnology, water filtration, and health and beauty industries. We have also manufactured tanks and vessels for WFI (Water for Injection) and CIP (Clean-in-Place) processes.

FAQ – Large Vessels 
What type of materials does Apache have experience with?

In Apache’s Beaver Dam facility, we work with 300 grade stainless materials, predominantly 304/L and 316/L. We also work with high alloy materials such as AL6XN, duplex 2304, 2205 and 2507, Inconel and Hastelloy

What types of heat transfer surfaces are available?

Dimple jacket, half-pipe, conventional jacket, electrical heat tracing.

What types of heads does Apache offer?

ASME F&D, F&D, Shallow F&D, Flat, Cone, Sloped, Hemi, Elliptical

What size heads can you fabricate?

We can fabricate Heads, anywhere from 30” (2’6”) to 192” (16’) in Diameter, with the thickness being 12 ga. to ¾” Stainless and up to 7/8” Carbon.

What is a wetted surface?

A wetted surface is a product contact surface or interior surface. It includes an area in nozzles up to the gaskets.

When do I use tri-clamp versus bolted connections?

Use tri-clamp connections for sanitary and quick connection applications.

What types of fittings are offered?

Depending on the application, we provide ANSI B16.5 150#, 300#, etc. RFWN, RFSO, and Lap Joint flanges, studding outlet (pad) flanges for standard ASME applications. For sanitary applications, we also provide tri-clamp ferrules, and tank bottom diaphragm valves such as ASEPCO, GEMU, PBM, NOVASEPTIC, etc.

What types of outlet valves are available?

Ball valves, diaphragm valves and gate valves. Some offer manual or pneumatic actuation options.

What types of insulation does Apache offer?

Mineral wool in various densities and foam glass. We can take a look at other insulation requirements that you may have.

What finishes are available?

Mill, 2B, No. 4, No. 4A, Bead Blast, Passivation, Pickle Passivation, and electropolishing

What is your tank weight capacity?

The weight limitation is dependent on the tank/vessel configuration, typically we want to keep the vessel below 70,000 lbs. We have built tanks weighing 250,000 lbs., but special consideration with outside riggers was required.

How wide of a tank can Apache build?

15 ft. diameter is the maximum typically.

What types of testing does Apache offer?

Liquid Dye Penetrant testing, hydrostatic testing, spray ball Riboflavin testing, pharmaceutical drain testing, surface finish testing, PMI (Positive Material Identification), and radiography (at an additional cost).

What types of FAT testing does Apache offer?

Hydro, Riboflavin, dye penetrant, saline, drain ability, radiography, agitation run testing

What certifications does Apache uphold?
  • NB/ASME U Certificate for Beaver Dam, WI
  • NB/ASME UM Certificate for Beaver Dam, WI
  • CE Marking Permission for Beaver Dam, WI
  • R Repair Certificate National Board of Boiler & Pressure Vessel Inspectors, Beaver Dam, WI
  • SELO License for Beaver Dam, WI
When does a tank need to be ASME Code stamped?

ASME Code is generally required on tanks above 15 psig or vacuum applications.

Who will coordinate my project?

A project engineer will coordinate communications, schedules and questions. There will also be a technical specialist that works on your project.

How do you keep customers abreast of the schedule?

On larger projects, updates to the schedule are communicated upon drawing approval submission, then once per month, after project changes or per customer requirements.

Does Apache manufacture its own agitators?

We work with leading agitator manufacturers and we also have made custom agitators for special applications.
