When custom process equipment becomes part of a critical operation, the details matter. The design, materials, fabrication, fit-up and final delivery all have to come together.

At Bendel, we design and fabricate reactors, pressure vessels, heat exchangers and other custom process equipment for demanding industrial applications. Every project brings its own requirements, and our team works through those details from engineering through fabrication and shipment.

And behind every finished vessel is the part that matters most: our people.

Skilled fabricators, welders, engineers, project managers and quality personnel work together to turn drawings and specifications into equipment our customers can depend on.

These photos are a good reminder of what that looks like, from hands-on fabrication to finished equipment ready for the field.

Happy National Tradesperson Day.

Every vessel and tank we build is the product of skilled hands. The welders, fabricators, and fitters who take pride in getting it right, weld after weld. Today we recognize the tradespeople whose craft is the foundation of everything we do.

Thank you for your skill and dedication.

Some of the most important work in a heat exchanger disappears from view once the heads go on.

For this vertical BEM exchanger, much of the story was on the inside.

The build included approximately 815 one-inch 316L stainless steel tubes, twisted-tape turbulators, baffles, and tube-to-tubesheet joints that were both seal welded and expanded.

But the numbers only tell part of it.

Our team had to install the tubes, complete the tube-to-tubesheet work, inspect those connections, and then work through the specialized twisted-tape turbulator installation before final assembly.

Those are the stages you rarely see once an exchanger is finished.

By the time the completed equipment is painted, assembled and ready to ship, the tubes, turbulators, welds and inspection work are all hidden inside.

That is where a lot of heat exchanger capability lives: in the details you can’t see in the finished photo.

Talk with our team about your next heat exchanger project.

Big equipment leaves very little room for small mistakes.
A heat exchanger may be measured in feet, but some of the work that determines whether it comes together correctly is measured much more closely.

Tubesheets are a good example.

Hundreds, sometimes thousands, of tube holes have to be drilled accurately, so components align, fit and move through fabrication as intended. Machined surfaces, hole patterns, and critical dimensions all become part of the larger build.

At Bendel, that work is supported by in-house machining capabilities including our Quickmill gantry machining center and vertical turning lathe.

The photos here show both sides of that process: the technology doing the work and the people behind it. Large machines provide the capability, but experienced operators are what turn drawings, dimensions and tolerances into finished components ready for fabrication.

With IMTS 2026 taking place this week, it is a good reminder that manufacturing technology is not separate from the finished vessel or heat exchanger. It is part of what makes the finished equipment possible.

Precision behind the build matters.

Replacement equipment has to do more than meet the process requirements. It also has to fit the plant that is already there.

Existing piping, nozzle locations, supports, access points and surrounding equipment can all affect how a new vessel needs to be designed and fabricated.

That is why replacement projects require careful attention early in the design process. Dimensions, orientations and connections need to be understood before fabrication begins, not discovered when the equipment reaches the field.

Whether replacing a reactor, storage tank or heat exchanger, the goal is the same: build the new equipment around the realities of the existing installation.

When a storage tank has to fit an existing installation, replication doesn’t always mean duplication.

For this approximately 37,000-gallon formaldehyde storage tank, the starting point was an established tank configuration already familiar to the plant.

Some things needed to stay consistent. The overall arrangement, roof, agitator configuration, and access requirements all had to work with equipment already in place.

Other details changed with the current application.

The upper shell was fabricated from 304/304L stainless steel, while the lower 48 inches of shell and the bottom were specified in 2205 duplex stainless for increased corrosion resistance. The floor nozzle was also 2205, while other components were selected from 304/304L and 316/316L based on their individual requirements.

The agitator support was another detail that required a closer look. During design, our team questioned the supplied beam-loading information and worked through the requirements with the customer and agitator vendor before fabrication moved forward.

That is the part of storage-tank reliability that is easy to miss from the outside.

Capacity matters. So do material selection, process conditions, mixing, heating, access, existing plant connections, and the details that have to be verified before fabrication begins.

With the storage tank industry gathering for NISTM this week, it is a good reminder that a tank may look simple from the outside, while the application behind it is anything but.

What do you do when a 20,000-gallon vessel needs to fit where there simply isn’t enough room?

You rethink the design.

For this project, site constraints meant a horizontal vacuum receiver wasn’t an option. Bendel engineered a vertical solution that maintained the required capacity while addressing the unique demands of full-vacuum service.

See the engineering behind The Tank That Had to Stand Up and how our team designed around the real-world constraints of the site.

Some equipment problems become much more expensive once installation has already started.

On a recent H₂S removal project for a renewable natural gas application, updated gas sampling changed the treatment requirement to a lead/lag system. That meant the equipment requirements had to change with it.

One question became especially important: Was the specified media weight dry or saturated?

The distinction mattered because the internal bed support had to be designed for the load it would actually carry. The final support design accounted for a load of nearly 59,000 pounds per vessel.

From there, the same discipline had to carry through the rest of the equipment: the internal support system, nozzle and manway locations, access structures, orientation, dimensional checks, inspection, and testing.

None of those details exist by themselves. They all connect back to how the equipment is expected to operate, be installed, and be maintained.

That is why the work on custom process equipment starts well before fabrication. It starts with understanding the requirement, identifying the questions that could become problems later, and making sure those answers are still reflected in the finished equipment.

The best time to prevent a field problem is before it becomes one.

How much of a storage tank is determined by what goes inside it?
For this replacement project in Iowa, the answer was quite a lot.

The service was 75% phosphoric acid, and the project requirements called for 316L stainless steel tank and process connections, a 1.69 design specific gravity, and a 1/16" corrosion allowance.

But the process influenced more than the material.

The operating requirements also had to account for sediment and solids accumulation, drainage, inlet location, and site containment. During design review, those needs translated into details such as a 1:40 sloped bottom, a carefully positioned inlet and nozzle arrangement, and a final 5,400-gallon capacity that fit the plant’s new containment area.

Getting the material right is only part of the job. The design details also have to support how the customer will operate, maintain, and integrate the equipment.

Turning those requirements into finished equipment took coordination across the Bendel team, from engineering and drafting through fabrication and quality. The completed API 650 tank included documented material traceability for its primary 316/316L components, along with final inspection and testing before shipment.

For process equipment, what happens inside the tank can shape nearly everything around it.
