Valve and pump packing performance improvement is usually approached from a procedure or specification process. Engineering and purchasing determine the parameters for the plant and create a procedure for selecting the packing type and how it is used. At many plants, this document is not often referenced or updated. Also, this process does not involve many stakeholders and is often one direction (top down).
As a result, this process can make the procedure thin and leave out important packing fundamentals details. This can lead to plants that rely on misleading and potentially incorrect information or world-of-mouth information. This affects the success of packing performance. A better method is to use the continuous improvement process to target improved packing performance.
