01 | Case Study 1.063686.00 Case Study 1.063686.00 | 02 Klaus Union Quality is our Success The Thought Process: All existing Bitumen pumps in that refinery were classified as “bad actors” due to high leakage rates and short seal lifetimes. Based on this existing experience, the following iterations were taken during the pre-engineering phase of the project: E Bitumen / Asphalt is prone to cracking when it reaches the atmosphere. Accordingly seals should be executed with API Plan 62 (steam quench), requiring additional utilities. Even under ideal conditions an API Plan 62 does not prevent leakage to the atmosphere, making the pump installation always a dirty spot. Additionally Steam supply may some- times fail or be outside permissible range, leading to regu- lar seal damage
