Kingflex
High thermal resistance, flame retardant structures built strictly to international energy standards.
Authoritative insights on the engineering requirements for thermal conservation, corrosion management, and cryogenic phase stability in energy extraction and processing.
In modern petrochemical refineries, offshore drilling rigs, subsea pipeline networks, and liquefaction terminals, thermal insulation systems act as critical infrastructure. These systems serve a three-fold purpose: thermal process energy conservation, personnel protection from hazardous temperatures, and the mitigation of Corrosion Under Insulation (CUI). CUI represents one of the most costly structural degradation mechanisms in downstream chemical processing. By employing closed-cell elastomeric structures, such as Kingflex NBR/PVC formulations, engineers can implement a resilient vapor barrier that physically blocks ambient humidity and liquid ingress from contacting carbon steel pipe substrates.
Choosing the correct insulation substrate requires balancing operating thermal ranges, structural dynamics, and environmental exposure. For cryogenic systems (such as LNG distribution lines operating down to -200°C) and mid-range industrial HVAC circuits, elastomeric rubber foam provides superior flexibility, vibration damping, and integrated vapor sealing. Conversely, for high-temperature steam lines, turbine housing systems, and heavy-duty refinery cracking furnaces, Rock Wool insulation serves as a fire-resistant barrier capable of enduring continuous exposure exceeding 600°C.
Designed for temperature ranges from -40°C to +105°C (cryogenic configurations down to -200°C). High flexibility, integrated vapor barrier, and excellent resistance to moisture absorption.
Capable of surviving extreme high-temperature environments. Standard in refinery steam pipes, heat exchangers, and areas requiring high mechanical strength.
Specialized systems formulated to handle extreme thermal stress, preventing stress cracks in liquid nitrogen and liquid natural gas transport piping systems.
Established under the umbrella of the Jinwei Group, which holds a rich manufacturing history dating back to 1979, Kingflex has stood as a pioneer of industrial thermal insulation. We operate as the first manufacturer of thermal insulation materials north of the Yangtze River.
At present, our manufacturing infrastructure incorporates 5 large-scale automated assembly lines. Our research, development, and high-volume production plant is situated in Dacheng, China—recognized globally as a center for green building and energy-saving materials.
