We find the right engineered solution where others cannot.
Full-service pressure vessel and heat transfer consulting: thermal design on the complete HTRI and HTFS suites, mechanical design to ASME and TEMA, and the judgment that only fifty years of difficult exchangers can buy.
Design, rating, and analysis.
Shell-and-tube & air-cooled exchangers
Thermal design of shell-and-tube, air-cooled, and forced/natural draft exchangers — on the full HTRI and HTFS program suites.
Pressure vessels, towers & columns
Mechanical design to ASME and TEMA specifications, including high-pressure and breechlock construction.
FEA & pipe stress
Finite element analysis for complex pressure vessels and structural elements; pipe stress analysis and pressure drop in piping systems.
Independent design review
A second set of senior eyes on a vendor's thermal or mechanical design — before you cut steel, not after.
Underperforming exchangers
Thermal troubleshooting of exchangers in service that aren't meeting duty — diagnosis and re-rating with HTRI/HTFS.
HTRI / HTFS thermal rating
Independent thermal rating of new or existing equipment against your process conditions.
High-pressure breechlock exchangers.
PVHTC has worked on more breechlock exchanger projects than anyone in Canada.
FIG. 2 — HIGH-PRESSURE BREECHLOCK END CLOSURE (SIMPLIFIED). The threaded breech ring carries the hydrostatic end load, so the channel can be opened for bundle access without cutting welds — a construction used in high-pressure services where the bundle must stay accessible. PVHTC has worked on more breechlock exchanger projects than anyone in Canada.
Thirty-plus years of consulting, across every process industry that moves heat.
- Oil refineries
- Gas plants
- Upgraders
- Sulphur plants
- Chemical plants
- Heavy oil
- Offshore drilling & production platforms
- Pulp and paper
- Power generation stations
New energy, same physics.
Hydrogen processing, carbon capture systems, and LNG pre-treatment rely on the same high-pressure shell-and-tube and reboiler design PVHTC has delivered for decades. If your project moves heat at pressure, the design discipline is already proven.
