Many associations, societies and regulatory agencies have rewritten and redeveloped emissions and leakage standards and controls year after year. When the process rules are changed, manufacturers of seals, packing and gaskets are forced to implement changes as well. The manufacturers either produce seals that are better suited to handle the new regulations or they drop out of the market. These changes affect the way end users must look at the quality of flexible graphite and its ability to seal. Click here to read more.
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.
