the solid plugs on the vessel body
(OP)
hi,the vessel I talking about is a natural gas huge filters , so I found some filters in my network were supplied with solid plugs with sizes vary from 1/4 to 2 inches installed directly on the vessels bodies(specialy the old types) It may be used as alternative access ,should I install a small valve before them or I can leave them as they supplied until they may be used

Just post your pictures one at at time. Not everybody can open download sites.
What you have is a pipe welded to the vessel. The end of the pipe is threaded with a coupling. The other end of the coupling is threaded with a square head plug. Are you finding some leakage around them?

I do not see why it is dangerous without a valve. It is easier to open a valve than to screw out the plug. For the plug you need a tool, for a valve you just need a hand unless the lever is removed. In any case you must make sure that nobody opens the plug (or the valve while) the vessel is under pressure. An instruction plate with a corresponding warning is definitely not wrong.
Once again check the ASME requirements (if any).

To make your HSE folks happy, I would install a threaded valve using a Schedule 160 nipple, and put the plug into that valve. The other good alternative is, if this nozzle never gets used, to weld up the threads amd make it a solid piece.
