Sanitary, Pharmaceutical and Industrial Construction
Every U-tube exchanger shares one geometry: a single tubesheet, tubes bent through 180 degrees, and a bundle that lifts out. What changes between them is the construction grade, the alloy and the paperwork that comes with it.
Five construction grades cover the range: Sanitary U-Tube, Pharmaceutical U-Tube, Industrial U-Tube, Stock & Custom Units and U-Tube Bundles. Every one of them shares the single tubesheet and the bundle that lifts out; the pages below say what changes between them and when each is the right call.
Tell us both fluids, the flows, the temperatures in and out and the pressures, and we will size the unit and say which construction grade the duty needs.

Sanitary U-Tube
316L wetted parts polished to a specified Ra, tri-clamp process connections, sloped and drainable shells, and bundles that come out for inspection. Built for 3-A duty and CIP circuits in food, dairy and beverage plants.
Pharmaceutical U-Tube
ASME BPE construction with documented weld procedures, controlled dead-leg ratios and material traceability. Double tubesheets where a tube leak cannot be allowed to reach product, WFI or clean steam.
Industrial U-Tube
ASME code stamped units in carbon steel through Hastelloy, TEMA R, B or C, shells to 48 inches. Built for high pressure, high differential temperature and the thermal cycling that breaks fixed tubesheet designs.
Stock & Custom Units
Two paths to the same duty. Shelf units in common sizes that ship in days when a unit fails mid-run, or an engineered build rated against your actual conditions when nothing standard fits.
U-Tube Bundles
The removable bundle is the U-tube's defining advantage, and replacing one is far cheaper then replacing an exchanger. Stock sizes, reverse-engineered builds and alloy upgrades that keep the original fit.
