HTRI Thermal Rating
Every duty independently rated with industry-standard HTRI software and validated against operating data.
SAMHWA
Thermal performance, guaranteed.
Heat Exchangers
Shell & tube and compact exchangers thermally rated for demanding duties across every industry.
Overview
Engineered heat exchangers, done properly.
SAMHWA designs and fabricates shell & tube, double-pipe and compact heat exchangers thermally rated with HTRI methods and mechanically designed to ASME Section VIII and PED. From single-unit replacements to multi-shell trains, we deliver guaranteed thermal performance with fully documented quality dossiers.
Our engineering team optimises each exchanger for fouling behaviour, vibration, thermal stress and maintainability — extending run-time between cleanings and maximising heat recovery across your plant.
Features
Designed in the details.
TEMA Configurations
All TEMA front-end, shell and rear-end types including fixed tubesheet, U-tube and floating head.
High-Integrity Welding
Qualified WPS/PQR procedures, orbital tube-to-tubesheet welding and 100% traceable consumables.
Fouling-Resilient Design
Velocity, baffle and layout optimisation to resist fouling and tube vibration across the operating envelope.
Exotic Metallurgy
