Heat Exchanger Manufacturers and Tube Drilling and Machining Performed In-House

A heat exchanger’s heart, the tubes, are the basic components of the shell and tube sheet heat exchanger, providing the heat transfer surface between one fluid or gas flowing inside the tube and the other fluid or gas flowing outside of the tubes.  Bendel Tank & Heat Exchanger works with our heat exchanger clients to design and manufacture custom heat exchangers that operate where the demands from high temperatures and pressures are significant.

Bendel Tank & Heat Exchanger provides a comprehensive, turnkey array of custom tube sheet drilling and machining design and service offering for any industry that requires the use of specialized and reliable heat exchanger equipment.

We invested in the Quickmill Intimidator 96 drilling equipment, along with trained, professional drilling operators, to give our clients and their heat exchanger projects large part machining and drilling accuracy.  Everything is done in-house in the Bendel Tank & Heat Exchanger manufacturing facility.

Our investment in a top-of-the-line and state-of-the-art machining and drilling program saves our clients money and time because we handle everything in-house in Charlotte, NC.

We design and fabricate to all TEMA configurations, from single pass to multiple pass exchangers.  Our Shell & Tubesheet Heat Exchangers can be fabricated from Carbon Steel, Stainless Steel or Nickel Alloy materials. They are designed, inspected and tested at our facility to meet stringent ASME and TEMA B, C and R standards.

Tube Sheet Contract Drilling & Machining Services from Bendel Tank & Heat Exchanger

Bendel Tank & Heat Exchanger offers contract drilling services for tube sheets, baffles and support plates. Our total approach to flexibility gives you many options for using Bendel as a contract drilling resource. 

We can purchase all material, provide expert drilling services, and then ship the finished project to you as a total turnkey service, or, you can ship your project to us and we will provide the expert drilling services and then ship back to you. 

We can handle any quantity of tube sheets. Tube sheets can be loaded on the driller table either singly or stacks up to 150mm maximum thickness. If table size permits, multiple stacks can also be drilled simultaneously by proper loading of plates and selection of spindles with the CNC control.

Bendel tube sheet drillers can accommodate most any size and shape of tube sheet or baffle plate. Round, half round, rectangular, or square plates can be programmed and drilled, as well as stacking multiple plates and loading multiple stacks. 

Our Quickmill Intimidator is the superior solution for large part machining and drilling accuracy. The Quickmill gives us increased production efficiency.

The Intimidator Gantry 96 (96″ x 185.5″) (2440 x 4711 mm) provides our craftsmen with a powerful, precise tool that performs flawlessly time after time. 

Intimidator Drilling Features:

• Fanuc 21i or 31i Control
• 75 hp (56 kW)
• 4000 rpm
• Through Spindle Coolant 

Intimidator Drilling Options:

• Probes
• Rotary Indexers
• Right Angle Head
• Hydraulic Part Clamping
• 1000 psi Coolant
• Twin Spindles 

Bendel tube sheet contract drilling service offers you: 

-  High production and cost savings by using multiple spindles for each drilling cycle.

-  Fast penetration drilling with high pressure coolant through the spindles to the drill points.

-  CNC control for positioning, feed rates, spindle RPM’s, and spindle selection, for fully automatic repeating drill cycles.

-  Automatic speed and feed variation during drilling cycles for maximum efficiency, as in drilling clad materials.

-  Dull drill detection by monitoring thrust on each drill.

-  Elimination of hand layout or templates.

-  Maximum thickness of single plate or stacked plates to 150mm.

-  Adjustable center drill spindles for various in-line hole pitch spacing's.

-  Coordinate positioning by moving work table on smaller machines or moving gantry bridge over stationary work table on larger machines.

U-tube Heat Exchanger Design and Fabrication from Bendel Corporation

There are several different types of shell and tube heat exchangers that Bendel designs and fabricates for clients of varying types for varying uses!  The U-tube heat exchanger is a multi-use heat exchanger that many of our clients use in their various manufacturing processes.

A shell and tube heat exchanger is a class of heat exchanger designs. It is the most common type of heat exchanger in oil refineries and other large chemical processes, and is suited for higher-pressure applications. As its name implies, this type of heat exchanger consists of a shell (a large pressure vessel) with a bundle of tubes inside it. One fluid runs through the tubes, and another fluid flows over the tubes (through the shell) to transfer heat between the two fluids. The set of tubes is called a tube bundle, and may be composed by several types of tubes: plain, longitudinally finned, etc.

Two fluids, of different starting temperatures, flow through the heat exchanger. One flows through the tubes (the tube side) and the other flows outside the tubes but inside the shell (the shell side). Heat is transferred from one fluid to the other through the tube walls, either from tube side to shell side or vice verse. The fluids can be either liquids or gases on either the shell or the tube side. In order to transfer heat efficiently, a large heat transfer area should be used, leading to the use of many tubes. In this way, waste heat can be put to use. This is an efficient way to conserve energy.

Heat exchangers with only one phase (liquid or gas) on each side can be called one-phase or single-phase heat exchangers. Two-phase heat exchangers can be used to heat a liquid to boil it into a gas (vapor), sometimes called boilers, or cool a vapor to condense it into a liquid (called condensers), with the phase change usually occurring on the shell side. Boilers in steam engine locomotives are typically large, usually cylindrically-shaped shell-and-tube heat exchangers. In large power plants with steam-driven turbines, shell-and-tube surface condensers are used to condense the exhaust steam exiting the turbine into condensate water which is recycled back to be turned into steam in the steam generator.

There can be many variations on the shell and tube design. Typically, the ends of each tube are connected to plenums (sometimes called water boxes) through holes in tubesheets. The tubes may be straight or bent in the shape of a U, called U-tubes.
