Boiler heating tubes are high-efficiency heat conduction components designed for industrial and commercial boilers. They are made of corrosion-resistant stainless steel or nickel-chromium alloy (NiCr). The spiral winding or seamless structure design greatly increases the heating area and improves the heat exchange efficiency. The power covers 1-20 kW, and can stably operate in a high temperature environment of 800-1200°C at a pressure of 1-3 MPa, suitable for steam generation or hot water circulation systems.

Industrial boilers (steam/hot water), commercial electric boilers, oil and gas boiler heat exchange components, medical sterilization equipment heating cores, laboratory high-temperature reactors, central heating circulation pipelines, solar-assisted heat exchangers, ship steam systems, food processing high-temperature sterilization modules, chemical fluid heaters, and hotel commercial electric water heaters.
Power range: 1kW~20kW (customizable, suitable for industrial boiler steam generation and commercial hot water circulation system)
Working voltage: 24V~480V AC/DC (wide voltage design, compatible with industrial-grade equipment)
Resistance value: 0.5Ω~20Ω (matched by voltage and power, support spiral/seamless structure customization)
Working temperature: 800°C~1200°C (nickel-chromium alloy is resistant to high temperature oxidation and suitable for high-pressure steam environment)
Material: stainless steel 304/316L, nickel-chromium alloy (NiCr) (customizable spiral winding or seamless pipe structure)
Dimensions: length 500 mm~3 m, outer diameter 5 mm~20 mm (supports non-standard processing such as bending and welding)
Service life: 50,000~100,000 hours (anti-oxidation coating + high-pressure sealing process, suitable for continuous high temperature and high pressure operation)
Efficient heat conduction: The spiral winding structure increases the heating area, and the thermal efficiency is increased by 40%, which is suitable for rapid steam generation in industrial boilers.
High pressure and high temperature resistance: stable operation at 1200℃, no leakage under 1- 3MPa pressure, suitable for petrochemical heat exchange scenarios.
Long-term anti-corrosion: 316L stainless steel + ceramic coating, anti-chloride ion corrosion,extendsd the life of the heating core of medical sterilization equipment.
Flexible adaptation: support bending pipe customization and special-shaped structure design to meet the needs of solar-assisted heat exchangers/ship steam systems.
Energy-saving and reliable: Energy efficiency ≥ 96%, seamless pipes reduce scaling risks and the maintenance cost of food processing sterilization modules.
Multiple protection: IPX6 waterproof + overpressure protection, suitable for the humid environment of hotel hot water systems.
Fast delivery: Standardized production line mass production, 25 days to complete orders, and adapt to the bulk purchase needs of commercial boilers.
