Pentair Industrial Heat Tracing Solutions has successfully integrated multiple state-of-the-art technologies in a Heat Management System to offer safe, reliable and cost effective sulfur transport. Our Heat Management System (HMS) for sulfur transfer pipeline includes Raychem Skin-Effect Heat- Tracing System, customized insulation and power distribution systems, Finite Element Analysis, CFD Analysis and Fiber-Optic Distributed Temperature Sensing. Our proprietary sulphur re-melt program for sulfur pipelines has proven to be the safest and most reliable approach to the critical issue of re-melting solidified sulfur without compromising the integrity of the pipeline. The introduction of Bundled Technologies in sulfur re-melt application basically eliminated the pipeline failures during sulfur re-melt. Safe sulfur transport With the increasing use of heavy crude, safe sulfur transportation is becoming increasingly important for the refining industry. Sulfur transport via heated pipelines is a viable alternative to transporting liquid sulfur by trucks over public roadways. This application has unique requirements due to the limited operating temperature range for liquid sulfur, pipe expansion and overheating concerns during re-melting of sulfur in the pipeline. Our unique Heat Management System combined with proven experience in engineering, procurement, construction and commissioning of sulfur pipelines often accompanies an Enforceable Warm Pipe Warranty the best in the Industry.
HEAT MANAGEMENT SYSTEM A Heat Management System (HMS) is an engineered system designed to maintain or protect process piping, equipment, vessels and instrumentation at pre-determined temperatures and within the defined design criteria.
