PT08 - Midstream Pipeline Applications � Design Aspects and Considerations for Mechanical Seals

Abstract

There are few applications that place a significant demand on mechanical seals such as those associated with the handling of various fluids through pipelines. Pipeline applications are unique in that they typically encompass variable fluid properties, along with fluctuations in pressure, temperature, and speed, sometimes through the same pumping equipment. There are additional challenges in the midstream pipeline sector associated with the remote nature of the installations and limited accessibility. Equipment monitoring and logistics of preventative maintenance support place an increased emphasis on the criticality of selecting a robust mechanical seal design and associated support equipment. The purpose of this tutorial is to serve as a guideline for the equipment user and define effective and efficient sealing strategies in midstream pipeline applications, integrating relevant industry best practices and lessons learned from field installations. The tutorial will draw upon the combined previous experience of the authors in addressing these applications.
