Using the right sealing materials in chemical transportation valve applications enables the safe and effective movement of chemicals, reducing the risk of non-accidental releases (NARs). It also minimizes the need for valve changeouts, which significantly reduces the total cost of ownership for an equipment owner or shipper. It avoids lost time involved in bringing equipment into a maintenance shop and waiting for an inspector to sign off on completed work, and it reduces labor costs for the maintenance itself. Stakeholders can ensure the right seal material is used for shipments by consulting a seal manufacturer experienced in performing chemical compatibility testing, material testing, and root cause failure analysis (RCFA). While chemical compatibility and material testing is performed upfront to ensure the best sealing solution is chosen, RCFA is conducted after a failure has occurred, to identify the cause of the failure and to assist in developing an improved solution that can prevent future failures. |
