Ceramic blankets are high-temperature insulation solutions designed to retain heat and ensure uniform temperature distribution during Post-Weld Heat Treatment (PWHT). These lightweight, flexible blankets are wrapped around pipes or vessels to protect the heating elements and prevent rapid cooling, which is essential for maintaining the structural integrity of the weld. This category features high-density, refractory ceramic fiber (RCF) blankets that offer exceptional thermal stability and resistance to chemical attack. Whether you are performing localized stress relieving or large-scale pre-heating, our ceramic blankets provide the superior insulation required to meet strict metallurgical cooling rates and industrial safety standards.
