High-temperature calcium silicate insulation engineered for petrochemical process equipment — reactors, cracking furnaces, reformers, heat exchangers, columns, and piping systems. Low chloride content, corrosion under insulation (CUI) resistance, and proven long-term reliability in demanding refinery environments.
The petrochemical and refining industry operates with process temperatures ranging from -50°C to over 1000°C across a wide variety of equipment. Insulation must not only provide thermal efficiency but also resist Corrosion Under Insulation (CUI), a critical concern for stainless steel piping and vessels in the 60–175°C range.
HR RHINO calcium silicate boards are manufactured with low chloride content and excellent chemical stability, making them safe for use on carbon steel and austenitic stainless steel equipment. Our products comply with ASTM C533 specifications for high-temperature industrial insulation.
Applications span the entire petrochemical facility — from ethylene cracking furnaces and catalytic reformers to distillation columns, heat exchangers, reactors, and steam piping systems. Our products deliver energy savings, personnel safety, and proven reliability in demanding hydrocarbon processing environments.
Six critical petrochemical and refinery system components where HR RHINO calcium silicate boards deliver superior thermal insulation and CUI protection.
Steam cracking furnaces operate at 750-900°C to produce ethylene and propylene. Our boards insulate furnace walls, roof panels, and coil support systems to maximize thermal efficiency and reduce fuel consumption.
Reforming and hydrocracking reactors process hydrocarbons at 500-600°C under high pressure. Our insulation maintains reaction temperatures, reduces energy costs, and protects personnel from extreme surface temperatures.
Atmospheric and vacuum distillation towers require efficient insulation to maintain precise temperature profiles. Our lightweight boards minimize heat loss while providing easy access for maintenance.
Shell-and-tube heat exchangers, reboilers, and condensers throughout the refinery benefit from our boards' low thermal conductivity and dimensional stability under thermal cycling conditions.
High-pressure steam lines, process piping, valves, and flanges throughout the petrochemical complex. Our custom-shaped insulation ensures energy efficiency and OSHA-compliant safe touch temperatures.
Pressure reactors, FCC units, and storage vessels require reliable long-term insulation. Our low-chloride boards are safe for austenitic stainless steel equipment, preventing stress corrosion cracking.
Engineered for demanding refinery environments with CUI protection and ASTM compliance.
Low chloride content and chemical stability help prevent Corrosion Under Insulation (CUI) on carbon and austenitic stainless steel equipment.
Our products meet ASTM C533 Type I & II specifications for calcium silicate block and pipe thermal insulation.
Low thermal conductivity dramatically reduces heat loss from process equipment, improving overall refinery efficiency and ROI.
A1 non-combustible classification provides passive fire protection for critical hydrocarbon processing equipment.
Pre-formed pipe covers, block insulation, and custom CNC-machined shapes for vessels, valves, flanges, and fittings.
