Fittings CRN Registration (CSA B51 Categories A to H) for Indian Manufacturers
Fittings are registered under CSA B51 in categories A through H, and the category determines exactly what evidence the safety authority needs. Getting the category right is half the job. Fitting portfolios are also where many manufacturers build a recurring relationship with us, because one accepted design covers repeated supply.
Codes: CSA B51 (Categories A to H) · ASME B16 series · ASME VIII (where applicable)
Who this is for
- ›Pipe-fitting, flange and expansion-joint manufacturers
- ›Specialty / instrument fitting makers supplying Canadian distributors
- ›Manufacturers building a multi-design fitting portfolio for recurring Canadian sales
What is included
- ✓Jurisdiction & pathway map (which province(s) you actually need)
- ✓Drawing & calculation review and normalization to Canadian expectations
- ✓Design calculations to the governing ASME / CSA code
- ✓Canadian-licensed P.Eng. review and authentication of the registration package
- ✓Statutory Declaration of compliance preparation (where required)
- ✓QC / quality program certificate review and acceptance pathway
- ✓Submission to the safety authority and correspondence on review comments
- ✓CRN number delivery, plus renewal / revalidation reminders
Fittings (CSA B51 Cat A to H)-specific considerations
- •Correct CSA B51 category determination (A to H): this drives the whole submission.
- •The >15 psi threshold and what falls inside vs outside registration.
- •Statutory declaration and proof-test / acceptance pathway per category (note: Category C has no ASME-authentication shortcut).
- •Portfolio registration: group multiple sizes/designs to reduce per-design cost.

Fittings (CSA B51 Cat A to H) CRN questions
How do you determine which CSA B51 category your fitting falls under? +
The category (A to H) depends on how the fitting is designed and proven: by standard, by proof test, by burst test, or by calculation. We classify your fitting and tell you exactly which acceptance route is fastest. Read our CSA B51 guide for the full table.
Does a fitting under 15 psi need a CRN? +
Generally, pressure-retaining fittings operating above 15 psig fall within CRN scope. Below that threshold, registration is usually not required, but the boundary cases matter, so we confirm before you spend on a submission.
