Canada TSSA, opinions wanted please
Canada TSSA, opinions wanted please
(OP)
I am looking for some opinions on TSSA inspection.
I am working on some assembly equipment that will be going in to Canada. This equipment will be supplied by the plant air supply. The airdrop is ½". The 1/2'" air drop then drops into a ¾" pipe used as a drip leg (with a ball valve at the bottom to drain any water). Do you think that this is now considered a pressure vessel of ¾" or greater and will require TSSA inspection?
Thank you
Bud

RE: Canada TSSA, opinions wanted please
TSSA has been quite reasonable to work with in the past, at least from my opinion, and this should likely be considered part of the piping without any supplemental requirements which are required for pressure vessels. I don't think they want the paperwork of calling every drip leg in a refinery a pressure vessel.
With the recent propane plant explosion they may be stepping up the oversight a bit but this should not be something to worry about.
My opinion only as I am not located in Ontario.

Does your drip leg assembly involve welding? Ooops...then it's a gray area. If you are mass producing them for sale, then it's a Category H fitting, not a vessel, and needs to be registered with TSSA (so you can get a CRN for the assembly). If it's simply part of piping, then you would register its design with TSSA, who would then need to witness its testing.
Far be it from me to counsel anyone to ignore a regulation of the Province, but I can say you would not be alone in successfully ignoring the requirement for TSSA registration of such a small item on an ordinary compressed air system. TSSA has far larger fish to fry...We've taken delivery of a sandblaster recently which has 1" threaded piping at its inlet, and I guarantee you that the sandblaster manufacturer doesn't even know who TSSA IS...

Bud,
By the letter of the regs you are dealing with system piping that is registered when you register the equipment skid. A drip leg in of itself isn't a fitting or a vessel.

RE: Canada TSSA, opinions wanted please
We have created an exemption letter for the plant that states we incorporate compressed air piping ¾" nominal pipe size and less. And that we are exempt from TSSA Ontario Regulation 220/01 made under the Technical Standards and Safety Act, 2000, in section 2.2.K.
So, we do not even reregister the skid.
The plant still says that we will need TSSA certification/verification of the Drip Leg because it has piping over ¾".
Thanks again,
moltenmetal, every time I see you handle all I can think of is Quasimodo dancing around saying molten metal, molten metal.
Oh, do you recognize Quasimodo. No, but his face sure rings a bell.
RE: Canada TSSA, opinions wanted please
Everything on your air system below 3/4" NPS involving no welding is exempt and requires nothing relative to TSSA- no inspection or testing. That goes for the actuator cylinders which of course are greatly larger than 3/4" NPS and may even involve pressure-retaining welds etc...If you have any air accumulators on there, they too will fall under the TSSA Act and require inspection etc.
My posture is bad, but not quite to the point of being called Quasimodo! And the molten metal is a hobby. I figured if people have been doing it for 3,000 years, then I could do it too.

That said, clients will sometimes ask for stuff to be cert that doesn't need it.
THAT said, unfortunately I can't lend any more clarity to your particular problem. Haven't had to tangle with air systems and fittings much, we deal more with the whole "what exactly IS more dangerous than water, anyway?" question.
