Beyond basic layouts
Detailed engineering services we offer
Advanced mechanical & structural analysis, beyond basic layouts.
Local Stress & Nozzle Reinforcement
+
WRC 107/537 and FEA verify shell integrity
against piping loads, before they become a field problem.
Horizontal Vessel Cradles
+
Zick analysis optimizes saddle support
placement and mitigates structural sagging on long horizontal runs.
Vacuum & Collapse Prevention
+
Custom vacuum rings and external ribbing
engineered for full-vacuum design conditions.
Blast Load Calculations
+
Structural deformation limits and peak
overpressure response, so control rooms and skirts survive accidental shockwaves.
Vessel Process Design Calculation
+
Process datasheet preparation, vessel
control scheme development, and vessel assessment reporting, completed alongside the
mechanical design so process and mechanical requirements stay aligned from the start.
What you receive
A complete, construction-ready package
Mechanical design calculation reports, nozzle reinforcement analysis, and internal FEA data, followed by 3D models, GA drawings, fabrication blueprints, and exact bills of materials.
Plus OSHA-compliant platform, ladder, and access structural drawings, so nothing's missing when materials hit the shop floor.

Equipment we design
A sample of the ASME vessel types we've delivered, grouped by application.
Slug Catchers
+
Large-diameter vessels separating liquid slugs from gas in
two-phase pipeline flow, sized to project flow conditions.
Slop Oil Drums
+
Recovery vessels for off-spec or recovered oil streams within
refinery and upstream process units.
Residue Gas Scrubbers
+
Scrubbing vessels removing entrained liquid from residue gas
streams before downstream compression or transport.
Reactor Vent Knock-Out Pots
+
Knock-out vessels protecting downstream piping and equipment from
liquid carryover in reactor vent service.
Propylene Rail Drums
+
Pressure vessels designed for propylene rail transport and
transfer service, to ASME Section VIII requirements.
Instrument Air Receivers
+
Pressure vessels buffering instrument air supply to maintain
stable control system air pressure.
Butane / Nā Compressor Trailers
+
Trailer-mounted compression packages for butane and nitrogen
service, designed for mobile or temporary deployment.
NG Booster Compressors
+
Natural gas booster compressor packages and associated vessels,
sized to project suction and discharge conditions.
Air Gas Transloaders
+
Transfer systems and associated vessels for loading and unloading
compressed air and gas between transport and storage.
Methyl Chloride Storage Vessels
+
Pressure vessels for methyl chloride storage, designed with
materials and seals suited to the stored chemical's properties.
Flash Vessels & Letdown Tanks
+
Pressure-reduction vessels separating flashed vapor from liquid as
process streams move to lower-pressure conditions.
Water Multimedia Filter Vessels
+
Filtration vessels for multimedia water treatment, designed to the
flow rate and media bed requirements of the system.
Accumulator Skids
+
Skid-mounted accumulator vessels buffering process flow or
pressure fluctuations ahead of downstream equipment.
Condensate & Recovery Solids Vessels
+
Vessels for condensate collection and recovered-solids handling
within process and utility systems.

FAQ
Frequently asked questions
What information do you need to get started?
+
A client data sheet covering operating pressure, temperature, and
process media is enough to begin. P&IDs and existing drawings help, but aren't required
up front.
Will I see the design before it's finalized?
+
Yes. You'll see calculation reports and model reviews as they're
produced, not just a finished package at the end. Adjustments happen during design review,
before fabrication starts.
What ASME codes do you design to?
+
ASME Section VIII Division 1 and 2, with TEMA and API 660 for heat
exchangers, and WRC 107/537 for nozzle and local stress analysis.
How do you catch errors before they become expensive?
+
Nozzle load, stress, and support checks run at the calculation stage,
using WRC 107/537 and FEA, before a design is released for fabrication.
Do I need to commit to a long-term contract?
+
We offer flexible engagement options, from single projects to
long-term contracts, so you can choose what fits your needs.
