Car-seal for valve
Car-seal for valve
(OP)
Valve size varies from 3/4” to 36 in.
Valve material is both carbon steel for utility piping and stainless steel valve for cryogenic service and non-cryogenic service.
I googled car seal and did not find much options. Some are galvanized CS band which, I think, may not be used for SS valve. Also plastic one can not last long.
I think best is SS car-seal but can not find one.
I am asking in general practice what type of valve car- seal is mostly used for oil and Gas industry.
Thanks

Just search for valves that can be used for low temperature applications. Once you find a suitable valve, simply specify whatever position locking device you need.

It was a nightmare, but for large plants, a very safe system.
On smaller plants I used plastic with a tag so we can put an ID on them. My latest move has been to incorporate the carseal into the LDAR system. Our valves are numbered and checked for VOC emmisions. During this inspection we verify the valve is sealed in the correct position. We can break a seal under a work permit.

To be sure, I haven't seen many in the oil and gas industry.

I've never come across an OSHA rule on carseals under PSM. They may have under some specialized hazards like climbing structures, bottles, or such.
