Section 1 amendments

18

Shop, Piping and First/Installation Inspections

4.1 - establishes and confirms inspection by TSSA – shop, first inspection, installation inspections are in accordance with CAD sections 1, 2 and 3 – code adopting sections for CSA B52, B52 and N285.0.

The inspection of a boiler, pressure vessel (shop inspection) or piping (piping inspection) shall be conducted by a TSSA inspector at any stage of its manufacture or installation, as per the Code Adoption Document sections 1, 2 and 3. Boilers and pressure vessels must be inspected by a TSSA inspector before the boiler or pressure vessel is first activated or put into use. This inspection is a “first” inspection for new boilers and pressure vessels or an “installation” inspection for used boilers and pressure vessels, when they are first installed at a new location.

Section 4 – new section

19

Shop, Piping and First/Installation Inspections

4.4 – addresses fittings – which are attached to BPV’s or piping and part of the inspections for the BPV or piping and are under the Certificate of Inspection for the BPV or piping:

Inspections of fittings must be included in all boiler, pressure vessel or piping inspections. The issuance of a certificate of inspection for a boiler, pressure vessel or piping, or the renewal of a certificate of inspection for a boiler or pressure vessel, as listed in section 5.2, includes its fittings.

35

How to submit an applicationBoilers & Pressure Vessels

You can submit 1 of 2 ways.

ACCIDENT REVIEW

42

OPERATIONAL DECISIONS THAT CONTRIBUTED TO THE INCIDENT

43

44

• Ammonia was detected to have leaked in to the curling brine system during the 2016/17 operating season at the Fernie Memorial Arena. Examination of the curling brine chiller after the incident identified the source of the leak as a carbon-steel tube failure in the curling system brine chiller.

• The failed tube showed evidence of corrosion pitting along the inner tube walls with accelerated pitting on an electric resistance weld line due to weld line fusion defects. A corrosion penetration occurred at a weld location resulting in a hole measuring approximately 2.2 mm x .2 mm with potential adjacent smaller holes along the weld line.

• Rising pressure from the ammonia leak into the isolated brine system exceeded the strength of a coupling joint in the brine system piping located near the curling chiller. The separated joint relieved the pressure, which resulted in rapid release and expansion of the ammonia within the brine system and solution.

• As shown in Figure 5, (next page) a segment of the brine system piping was connected by two in-line water system couplings. One coupling was oriented vertically while the other horizontally. The pipe segment weight was supported on a wooden block at one location. There was no support for either longitudinal or torsional loading.

• The horizontal coupling was found separated as shown in Figure 5 and Photo 8.

50

Photo 8 separated coupling at Fernie

51

• As part of the investigation, a test was conducted to evaluate the pressure required to separate a similar pipe coupling. A new exemplar coupling was installed per the manufacturer’s specifications onto 4-inch diameter piping similar to that used at the Fernie Memorial Arena. The pipe-coupling joint was pressurized and at 30 pounds per square inch (psi) the coupling began to slip toward separation.

• The curling chiller is protected on the shell side (ammonia) by an over-pressure relief device set to relieve at 150 psi. This valve was tested and demonstrated to relieve at the designed pressure. An inspection revealed no evidence of brine deposits within the valve. It is concluded that the overpressure relief device likely did not activate.

52

It is estimated that the pressure within the brine system reached between 30 psi and 150 psi. The friction from the weight of the pipe and the torsional friction of the vertical coupling would have added to the force needed to separate the coupling beyond that associated with the 30 psi coupling separation pressure.
