Fired Heater Tube Seals
Our fired heater tube seals prevent air ingress in industrial heaters, reducing fuel costs and emissions. Engineered with patented designs, these seals maintain integrity at temperatures up to 1950F. Custom configurations ensure compatibility with various heater designs while delivering measurable energy savings for petrochemical and power generation clients.
Expansion Joints
Custom fabric expansion joints accommodate thermal motion and vibration in high-temperature systems. Constructed from advanced materials, these joints withstand temperatures up to 2600F while resisting abrasion and chemical corrosion in industrial exhaust applications.
High-Temperature Gaskets
Specialty gaskets for extreme thermal environments include tadpole, hat-seal, and flat-face designs. Available in multiple material combinations, these gaskets maintain sealing integrity from 500F to 2900F across various industrial equipment and piping systems.
Specialty Textiles
High-temperature textiles include ceramic papers, silica cloths, and metal mesh composites. These materials provide thermal insulation, fire protection, and sealing capabilities for industrial applications ranging from welding to gas turbine operations.
Pigtail Insulation Jackets
Custom-engineered insulation jackets for pigtail tubes on steam methane reformers. These weatherproof, reusable jackets maintain temperatures up to 550F while reducing installation time and maintenance costs compared to traditional metal jacketing systems.
