Mechanical Design & Workshop Fabrication Detailing
COREX Engineering provides specialized mechanical design and workshop detailing for heavy static equipment utilized in oil refining, chemical synthesis, fertilizers, cryogenic storage, and offshore installations. Our mechanical engineers have extensive experience designing pressure vessels, columns, reactors, shell and tube heat exchangers, and storage tanks strictly to ASME Section VIII Div 1 & Div 2 and TEMA standards.
From initial design calculations in PV Elite to full workshop fabrication general arrangement drawings, nozzle orientation plans, and weld development sheets, we deliver complete manufacturing-ready engineering packages.
Key Technical Deliverables
ASME Section VIII Pressure Vessels
Internal and external design pressure calculations, minimum design metal temperature (MDMT), shell thickness, and head sizing.
TEMA Shell & Tube Heat Exchangers
Mechanical design of tubesheets, floating heads, channel covers, baffles, and tie rods conforming to TEMA R, C, or B classes.
Distillation Columns & Tray Detailing
Tall tower wind and seismic design, skirt support calculations, vortex shedding analysis, and internal tray support rings.
API 650 & API 620 Storage Tanks
Design of cone-roof, dome-roof, and floating-roof storage tanks with annular ring calculations, wind girders, and nozzle reinforcement.
Nozzle Reinforcement & WRC Calculations
Local stress analysis around vessel nozzle junctions under piping thermal loads using WRC 107/537 and FEA finite element methods.
