This video really amazing for whoever working brown field PIPING engineering and construction. Please make more videos about piping tie in in the existing line. Usually what kind of difficult in the working brown field PIPING tie in and construction issue. Please make video about this topic
In my view 1.If you done positive isolation in piping system its called effective isolaystem 2. watch in video 1:32 there are show various type of mechanical isolation methods,Cab select anyone of method based on industry safety aspects. Thanks for comments.
in the middle of the diagram used in explaining the double block and bleed isolation drawing that looks like a small circle what is the uses and what is it called .
Yes,1 st and 2nd also positive isolation but its not suitable(safety wise) for Hazards services system. Also various isolation techniques order based on safe methods from low level to high level. Thanks.subscribe @technicalpiping
@@TECHNICALPIPING This could be misunderstood. Gate valve and bleed valve is not positive isolation. The ideology behind positive isolation is to guarantee 100% physical segregation of a hazard or contamination from personnel and/or product inventory. Positive isolation is limited to the use of blind flanges(removable spool and blind flange), spectacle blinds, and spades.
