We are ASME Code certified for manufacturing (U) and National Board for repairs & alterations (R). Our team knows and understands 3A design and has a close working relationship with USDA equipment inspectors.



Stainless steel grades 304, 304/304L, 316, 316/316L and higher grades such as 2205 duplex

Welding Technology

GMAW, GTAW by hand, machine: seam welder, and Orbital: tube to tube & tube to tubesheet.


Supplier finishes: Standard Mill plate & 2B sheet, and polished 10Ra to 32Ra
In-house finishes: 32Ra or better hand polished interior welds, taped & color cleaned interior and/or exterior welds and uniform bead blast welds and/or exterior surfaces.

Featured Capabilities

We have the usual array of cutting and shearing equipment, such as this semi-automatic bandsaw.

Ultrasonic thickness checkers are used to verify stainless thickness.  A variety of borescope, video, and test equipment is used throughout the process to assure compliance.

One of the many borescopes for inspecting surfaces not readily accessible, such as the inside of tubes and piping.

The Mahr Pocket Surf is an industry standard for assuring the surface finish meets or exceeds dairy standards.

Transforming a sheet into a barrel by way of the DAVI plate roller.

Large tank rollers support this evaporator as we begin stuffing it with tubes using a mechanized hydraulic tube pusher.

A TriTool portable mill cuts the tubes to the perfect recess to assure proper weld where the ends are welded to the tubesheet.

Orbital tubesheet welder seal welds the end of each tube to the tubesheet.  These welds are then ground and polished to dairy standards.

Separate bay designed for bead blasting stainless steel equipment. Bead blasting exterior surfaces and welds creates a uniform finish by removing scratches, grinding marks and leftover color from welding.

High speed beveler prepares the barrel end sections for welding together.

Seam welder 12 feet in length for welding 16 ga to 3/8″ thick plate (10 feet long if rolling is required).

Vacuum lifters and heavy vinyl assure a mar-free surface when handling stainless sheets.

As an option, finished products can be shrink-wrapped for the trip to their final destination.
