Statistics on static sealing points.
Thread Content
Dear experts, how should static sealing points in petrochemical plants be counted? Should the flange be counted as one, and the pressure gauge connector as another? How to calculate valves (two flanges and one large cover)? Should the stuffing area of the valve stem be considered a dynamic seal or a static seal? How then should ball valves be calculated? If there is internal leakage in the valve at the drain or vent point of the pump pipeline, does that count as a leak at a static seal?
The packing gasket seal at the valve stem also counts as a static seal point; in addition, there are four static seal points at the front and rear flanges as well as at the valve body cover； Pump condensate discharge and venting are also considered static seal points; are you creating an LDAR inspection form?
Article 7: Calculation principle for static sealing points: One static sealing joint is counted as one sealing point. For example: a pair of flanges, regardless of their size specifications, is counted as one sealing point. A valve is generally considered to have four sealing points. If the valve body is equipped with an additional plug or there is a connection for venting behind the valve, one additional unit should be counted (exceptions apply to special valves). A threaded union counts as three sealing points. One leak is counted as one leakage point; whether it is a seal failure, a weld crack, an erosion pit, or any other type of leak, regardless of its size, it is all included in the count of leakage points.
No, I am responsible for counting the sealing points
It’s difficult to cover everything in this area, even for those who work full-time on it
