As the world’s largest provider of complete electrical heat management systems, primarily for the general process, oil and gas, chemical, and power generation industries, Pentair Industrial Heat Tracing Solutions provides innovative products and turnkey solutions under market-leading brands—Raychem, Pyrotenax, Raychem, and Tracer. Our premiere turnkey solutions include full life cycle support—ranging from front-end engineering and installation to maintenance and operation services. Our global experience and office presence in 48 countries uniquely position us to manage the heat needed for projects of any size and scope.
Raychem STS Skin Effect Heating technology is a unique and most effective heat-tracing option for heated sulfur pipelines. 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.
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.
