Engineering Calculations for Process Equipment
Detailed engineering calculations for reactors, vessels, heat exchangers and storage tanks, covering shell and head thickness, jacket design, nozzle reinforcement, agitator power, heat transfer area and structural supports, prepared to ASME / IS design codes. These calculations form the technical backbone of any new equipment order or design review, and getting them right up front avoids costly rework during fabrication or after installation.
What's Covered
Our engineering team prepares shell, head and jacket thickness calculations as per ASME Section VIII / IS 2825, heat transfer and utility load calculations to size exchangers and jackets correctly, agitator power, torque and shaft design calculations for mixing duty, and nozzle reinforcement, lug and support design to ensure the vessel can be safely lifted, mounted and piped.
When You Need This
This service is typically used ahead of a new equipment fabrication order, when modifying an existing vessel's duty (higher pressure, new agitator, added jacket), or when a regulatory or client audit requires documented calculations behind an in-service asset that were never formally recorded at the time of original fabrication.
Deliverables
You receive a calculation package referencing the applicable design code clauses, suitable for internal engineering review, vendor fabrication drawings, or submission to a third-party inspection agency as part of equipment qualification.
Frequently asked questions
- Which design codes do you work to?
- Calculations are prepared as per ASME Section VIII and IS 2825, matching the code basis most commonly required for pharma and chemical process equipment in India and for export orders.
- Can you calculate for an existing vessel that has no original design documentation?
- Yes, we can back-calculate and verify design margins for an existing vessel based on its as-built dimensions and current operating conditions, which is common when documentation from original fabrication has been lost.
- Do you cover agitator and structural support calculations too, or just pressure parts?
- Both. The service covers agitator power, torque and shaft sizing, and nozzle, lug and support design, in addition to shell, head and jacket thickness calculations.
