Brand Introduction

Heavy industries face critical challenges with welding residual stress causing construction failures, uneven temperature distribution in large-scale vessels, and mechanical loosening in high-vibration environments. Wujiang Hongcheng Heating Equipment Co., Ltd., headquartered in Suzhou, China, addresses these pain points through specialized ceramic heating solutions developed in collaboration with Zhejiang University. As a recognized global supplier for Saudi Aramco and technology patent holder for DSP+IGBT Air-Cooled Induction Systems, Hongcheng delivers high-precision thermal control that ensures structural integrity across petrochemical, aerospace, and energy infrastructure projects.

Core Technology & Products

Hongcheng's ceramic heating portfolio solves uneven temperature distribution in complex welding geometries through three specialized product lines:

Ceramic Pad Heaters (60V & 80V Options): Flexible heating elements conforming to various pipe diameters and vessel shapes, enabling localized preheating and post-heating for circumferential and longitudinal seams. The dual-voltage configuration accommodates diverse power infrastructure requirements across international project sites.
Bank Channel Heaters: High-intensity heating systems designed for large-surface applications requiring rapid thermal ramping. These units integrate with PID temperature control systems and Japanese CHINO recorders (models AH4000, EH3000, EL3000) for automated curve printing and precision soaking conditions.
