Herence Technology focuses on insulation engineering for the complex operating conditions of refining units, deeply covering the comprehensive insulation needs of high-temperature heavy oil pipelines, various chemical product transmission lines, steam tracing systems, and general petrochemical product storage and transportation processes. Addressing the characteristics of diverse media and significant temperature fluctuations in refining environments, we strictly employ high-performance insulation materials that combine high-temperature resistance, fire protection, and high compressive strength, fundamentally resisting the erosion of the insulation layer by various operating conditions or liquids. Through precision cladding structures and rigorous sealing techniques, we construct a highly stable, low-thermal-conductivity composite insulation layer. This not only effectively prevents heat loss to ensure the energy efficiency of steam tracing systems but also ensures that complex media maintain precise process temperatures under extreme conditions, eliminating the risks of local condensation and equipment corrosion caused by thermal bridges. Herence Technology thus provides a solid and reliable insulation guarantee for the safety management, energy efficiency improvement, and long-term stable operation of refining units.
