Calculate. Verify. Submit.

Purpose-built for pressure vessels and heat exchangers — the two vessel types that fall under IBR jurisdiction.

Module A

Pressure Vessel

Quick Calc →
Vertical Pressure Vessel Engineering cross-section drawing of a vertical pressure vessel per IBR Edition 2016 N1 N2 N3 MW TL–TL = 2400 mm ID = 1200 mm t = 16.4 mm Reg. 283 2:1 Elliptical head Reg. 317 · t = 14 mm Girth weld seam 100% radiography
  • Shell thickness — vertical & horizontal
  • Elliptical & hemispherical dished ends
  • Nozzle reinforcement & man-way design
  • PWHT, radiography & hydro-test evaluation
  • IBR registration fee calculator (Reg. 385)
Module B

Heat Exchanger

Quick Calc →
Shell and Tube Heat Exchanger Engineering cross-section of a horizontal shell and tube heat exchanger per IBR Edition 2016 S1 S2 HOT T1 IN COLD T2 IN HOT T1 OUT COLD T2 OUT ID = 800 mm Effective tube length = 3660 mm Tube sheet IBR Reg. 283 Segmental baffle Spacing = 300 mm · 25% cut Hot fluid tubes Cold fluid tubes
  • Shell-side & tube-side independent inputs
  • Tube sheet thickness calculation
  • Fixed & floating head design support
  • Heating surface area computation
  • IBR requirement flag (as per client)

The average IBR calculation takes 4–6 hours in a spreadsheet.

IB-PRO does it in under 10 minutes — with full clause traceability and a submission-ready report.

How it works

From parameters to approved document.

Three steps. No regulation hunting. No formula errors.

1
Step one

Enter design parameters

Shell dimensions, pressures, temperatures, materials, nozzle details. Structured exactly as your IBR submission requires.

2
Step two

Instant IBR calculation

Shell thickness, dished ends, nozzle reinforcement, hydro-test, PWHT — evaluated against exact IBR clauses, in real time.

3
Step three

Export & submit

Download Word or PDF sheets formatted for the Director of Boilers or a Competent Authority — ready to sign, stamp, and file.

Material database

Every IBR material. Pre-loaded.

Select from every IBR-permitted material. Allowable stresses pre-populated from ASME Sec. II Part-D by design temperature — no manual lookup, no transcription errors.
