Joshua James, Liquip, Australia, provides maintenance tips and advice to ensure smooth operation during loading operations.
T
o reduce downtime and ensure continual smooth operations at each terminal, it is vital to implement and follow a regimented equipment maintenance programme. For instance, API couplers and loading arms provide a critical connection between the tanker and terminal, and it is not unusual for API couplers to experience in excess of 50 connections in a single day. By looking out for and addressing the following areas within their existing maintenance schedules, terminals can ensure their equipment is cared for and will continue to provide the utmost safety, reliability and performance:
Seal selection As the temperature fluctuates in warm or cold climates, and depending on which products and additives flow through the loading arms, it is crucial to use the right product seals for the job. Using incorrect seals may cause the coupler and loading arm seals to become compromised, leading to product leaks. There are a wide variety of product seals available on the market ranging from seals designed to handle typical loading of fuels to those designed to handle ultra-low temperatures and even some harsh chemicals. To determine which seals are best suited to an application, an API coupler manufacturer should be contacted.
Seal wear A coupler performs a high number of connections each day which can cause seals to wear over time. Worn seals may cause minor leaks during loading or after the coupler has been disconnected from the truck API adaptor. This is usually an indication that the product (nose) seal, or one of the other seals such as the poppet adaptor O-ring or bush and O-ring, are due for replacement. Terminal operators should inspect couplers on a regular basis and
