Design Questions

Q : Do I need to register my piping system?
A : Please read Ontario Regulation 220/01 and/r refer to Safety Bulletin SB007 REV.4

 

Q : How can I change the company’s name or address on registered welding/brazing procedures?
A : The following documents need to be submitted to TSSA BPV Engineering:
A cover letter requesting the change of the name or address, the reason for the change and indicating both: the old and new name and/or address information. Please include a list of the registration numbers.

The PQR will remain the same, as it cannot be changed according to ASME section IX. You must create a new WPS to reflect the new company name and/or address. Your Quality Assurance program must reflect the source of the PQR as being from the previous owner/company name or previous address.

As the PQR is the registered document and it cannot be changed, TSSA does not re-stamp any documents or issue any revisions.
 

Q : How do I obtain copies of my registered documents (CRN’s)?
A : Please send an e-mail with your request to publicinformationservices@tssa.org. Please include your full contact information and specifics on what you require.

 

Q : What documents do I need to submit for renewal of fittings registration?
A : The renewal process is the same as applying for a new CRN. Please follow the fitting registration guideline. If you wish to retain the same CRN, please include in your application package a letter requesting renewal and a photo copy of the originally approved Statutory Declaration(s).

Q : What do I need to submit for a company name/address change of registered fittings?
A : If you wish to have name/address changed for an existing Fitting Registration for Ontario only, then you will need to submit the following:
. a cover letter requesting and specifying why the name/address change is required and reference to the existing CRN number;
. two updated originally signed and notarized TSSA Statutory Declaration forms;
. a copy of the previously issued Ontario stamped Statutory Declaration;
. a copy of a valid quality program certificate, e.g. ISO etc.

For National Service you will be required to submit the following:

. two updated, original signed and notarized ABSA Statutory Declarations;
. a copy of the previously issued stamped Statutory Declarations for each of the provinces (where registrations exist);

This process applies to each CRN that is being changed.

Q : How do I register a boiler, pressure vessel, fitting or piping system design in Ontario?

Q : What is a Canadian Registration Number (CRN)?
A : The Canadian Registration Number (CRN) is a number issued by each province or territory of Canada to the design of a boiler, pressure vessel or fitting. The CRN identifies the design has been accepted and registered for use in that province or territory. The province or territory is represented by numeric digits following the decimal point within the CRN as shown in the list below. The first registering province or territory is the first digit after the decimal. For example, a design registered first in Ontario and then in Alberta might be issued the number 4321.52:

1 = British Columbia
2 = Alberta
3 = Saskatchewan
4 = Manitoba
5 = Ontario
6 = Quebec
7 = New Brunswick
8 = Nova Scotia
9 = Prince Edward Island
0 = Newfoundland
N = Nunavut
T = Northwest Territories
Y = Yukon Territory

C, follows the designation of the province of first registration if the design is subsequently registered across Canada (e.g., M 4156.5C shows the design as first registered in Ontario, then across Canada)

Q : What is an Ontario Identification Number (OIN)?
A : The Ontario Identification Number (OIN) was a number issued by TSSA to uniquely identify each boiler and pressure vessel in Ontario during the period 1965 to June 2003. OIN's were issued for boilers and pressure vessels that had a valid CRN, had been inspected and found acceptable. The OIN is no longer issued by TSSA.
