SULFUR TRANSPORT PIPELINESafe, Reliable and Cost-Effective Heat Management System
INDUSTRIAL SOLUTIONSAs the world’s largest provider of complete electrical heat management systems, primarily for the general process, oil and gas, chemical, and power generation industries, nVent 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.
THE HEART OF OUR SOLUTIONSnVent RAYCHEM STS Skin Effect Heating technology is a unique and most effective heat-tracing option for heated sulfur pipelines. nVent 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 TRANSPORTWith 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.

3D Finite Element Analysis
3D Finite Element Analysis is an integral part of nVent sulfur transport pipeline heat management system.
CAPABILITIES
• Simulate the temperature profile of sulfur across the cross section of the pipe
• Determine the heat-up or cool-down characteristics of the sulfur line through transient analysis
• Simulate the temperature profile along the length of pipe
BENEFITS
• Ensures that sulfur temperature does not fall below the solidification temperature across the cross section of the pipe
• Determines the time available before the sulfur solidifies due to power failure under varying ambient conditions
• Analyzes hot spots and voids throughout the sulfur re-melt process

nVent has a proven track record of implementing distributed fiber-optic temperature sensing solutions which provide critical insight into the temperature profile along the entire length of pipe.
CAPABILITIES
• Temperature profile with 1ºC accuracy and 1 m resolution along the length of the pipeline
• Capable of sensing temperatures for up to 20 km (12.5 miles) of pipeline from each station
BENEFITS FOR SULFUR TRANSPORT PIPELINES
• Prevents pipe damage during re-melting of solidified sulfur by precisely locating hotspots or voids along the entire length of the pipeline
• Senses temperature for long sulfur transport pipelines with multiple flow paths
• Facilitates the commissioning process by pinpointing the locations of inadequate, absent, or damaged insulation along the entire length of the pipeline
