Ceramic Heater Product Catalog | Wujiang Hongcheng Electric Heating Equipment

Wujiang Hongcheng Electric Heating Equipment Co., Ltd. delivers industrial-grade ceramic heater solutions engineered for precision heat treatment, pre-weld preheating, and post-weld stress relief across petrochemical, power, and heavy manufacturing sectors. With surface temperatures reaching up to 1,000°C (theoretical maximum 1,050°C), Hongcheng ceramic heaters combine oxide lead ceramic insulation, nickel-chromium heating wire, and flexible mechanical design to meet the most demanding industrial thermal processing requirements.

Product Series: Industrial Ceramic Heaters

Hongcheng’s ceramic heater lineup is purpose-built for localized thermal processing in heavy industry. Each series addresses a specific pipe diameter range, component geometry, and operational environment, ensuring precise, uniform heat delivery across welded joints, pressure vessels, and pipeline systems.

LCD Crawler / Caterpillar Ceramic Heater

Series Overview

The LCD Crawler Ceramic Heater — also known as the caterpillar ceramic heater — is Hongcheng’s flagship flexible heating element designed for large-diameter vessels, pressure tanks, and complex pipeline geometries. Its articulated ceramic block construction allows the heater to be spliced, bent, or wound to conform to irregular surfaces, making it the preferred ceramic heater solution for on-site heat treatment of spherical tanks, towers, and large-diameter weldments.

Key Technical Specifications

• Insulation Material: Oxide lead ceramic with high-strength construction and superior thermal radiation properties
• Heating Element: Nickel-chromium heating wire with new-process welded joints for extended service reliability
• Maximum Surface Temperature: 1,000°C (theoretical maximum: 1,050°C)
• Heating Method: Resistance heating combined with infrared (radiation) thermal output
• Mechanical Flexibility: Splicing, bending, and winding configurations supported to fit complex geometries
• Power Density: High power density enabling rapid heating speeds that exceed induction heating methods
• Compatible Sensors: Standard K-type (Nickel-Chromium / Nickel-Silicon) thermocouples
• Compatible Controllers: DKW series intelligent temperature control boxes; supports various voltage inputs

Differentiated Technical Advantages

• Efficiency: Heating speed surpasses induction methods due to high power density ceramic element design
• Thermal Radiation: Oxide lead ceramic blocks emit superior radiant heat for even thermal distribution across workpiece surfaces
• Structural Adaptability: Articulated crawler design accommodates pipes, vessels, and structural components of varying diameters and geometries
• System Integration: Seamlessly pairs with the DKW/Intelligent Temperature Control Box for automated heating cycle management, digital temperature setting, and silicon-controlled rectifier switching

Primary Applications

• Pre-weld preheating for large-diameter pipeline welds
• Post-weld heat treatment (PWHT) and stress relief for pressure vessels
• Localized heat treatment for spherical tanks and column towers
• Overall heat treatment for electric desalting tanks
• On-site heat treatment in petrochemical refinery construction
• Structural component stress relief in metallurgical and shipbuilding industries

SCD Rope-Type Ceramic Heater

Series Overview

The SCD Rope-Type Ceramic Heater is Hongcheng’s specialized ceramic heater solution for small-diameter pipes, elbow joints, and geometrically irregular weld areas where crawler-type heaters cannot conform effectively. Its rope construction achieves a minimum bending diameter of 70mm, making it indispensable for power plant maintenance, pipeline head heat treatment, and precision joint thermal processing.

Key Technical Specifications

• Minimum Bending Diameter: 70mm — suitable for small-bore pipeline and irregular joint heat treatment
• Heater Form Factor: Flexible rope construction
• Primary Use Case: Small-diameter pipe preheating and weld joint heat treatment
• Compatible Sensors: Standard K-type (Nickel-Chromium / Nickel-Silicon) thermocouples
• Compatible Controllers: DKW series intelligent temperature control boxes

Differentiated Technical Advantages

• Ultra-Compact Bending Radius: 70mm minimum bend diameter enables heat treatment in confined pipeline configurations and tight-radius elbows
• Geometric Versatility: Rope form factor adapts to irregular joints and small-bore fittings where standard heating pads are impractical
• Precision Thermal Delivery: Focused heat concentration on small joint areas ensures consistent thermal cycling for weld integrity

Primary Applications

• Small-diameter pipeline preheating and post-weld stress relief
• Power plant maintenance — pipeline head heat treatment
• Elbow, tee, and irregular weld joint localized heating
• Heat treatment in confined-space industrial environments
• Petrochemical and natural gas pipeline maintenance operations
