PRODUCT OVERVIEW
Flexible Ceramic Pad Heating Elements are high-performance resistance heating solutions designed for pre-weld and post-weld heat treatment (PWHT) of pipe welds and fabrications. Manufactured by Cooperheat using durable Nickel Chrome heating wire, these flexible heating pads provide uniform and controlled heat distribution up to 800°C. Engineered for industrial heat treatment applications, they deliver reliable thermal performance, easy installation, and adaptability across a wide range of pipe diameters and fabrication geometries.
Product description
Flexible Ceramic Pad Heating Elements are specifically developed for localized industrial heat treatment processes, including preheating and post-weld heat treatment (PWHT) of pipelines, pressure vessels, and structural fabrications. Designed to operate at temperatures up to 800°C, these ceramic pad heaters provide consistent and even heat distribution, ensuring proper temperature control and compliance with heat treatment specifications.
Constructed using high-quality Nickel Chrome resistance wire embedded within durable ceramic beads, the heating elements are capable of withstanding demanding industrial environments. Their flexible design allows the pads to conform closely to curved surfaces such as pipe welds and complex fabrication joints, ensuring efficient heat transfer and minimizing thermal loss.
Operating at 45A current, the heating pads are available in power ratings of 2.7kW and 3.6kW, providing options to suit varying heat treatment requirements. The flexibility and modular nature of ceramic pad heaters make them ideal for use with transformer power units, temperature controllers, and multi-zone heat treatment systems.
Widely used in industries such as oil & gas, petrochemical, power generation, and heavy engineering, Flexible Ceramic Pad Heating Elements offer a reliable and efficient solution for achieving controlled heating, improved weld integrity, and compliance with international heat treatment standards.
