The 4m steel fin tube for water heaters is engineered to optimize hot water production efficiency by combining extended length, enhanced heat transfer, and durable materials. It features a high-carbon 1020 steel core (known for its excellent thermal conductivity) and stainless steel 304 fins (resistant to rust in humid water heater environments), creating a composite structure that balances heat transfer performance and corrosion resistance. The 4-meter continuous length is a key advantage: it reduces joint connections by 75% compared to 1m alternatives, eliminating potential leakage points and simplifying installation. The finned design (25 fins/inch, 0.3mm fin thickness) ensures uniform heat distribution across the tube surface, minimizing hotspots that can reduce efficiency or damage the tube. This makes it ideal for residential, commercial, and industrial water heating systems where reliability and energy efficiency are top priorities.
Length Advantage: The 4-meter continuous length reduces the number of connections needed for a typical water heater (e.g., 1 connection for 4m vs. 4 connections for 1m tubes), lowering leakage risks by 75%. It also cuts installation time by 40% compared to assembling multiple 1m tubes, as fewer connections mean less sealing (with high-temperature silicone gaskets) and pressure testing. The length is compatible with most water heater tank heights (1.5-2.5m) when coiled or U-bent, requiring minimal modification.
Heat Transfer Rate: The stainless steel 304 fins and 1020 steel core work together to achieve 1800 kcal/h·m²·°C thermal output—20% higher than all-carbon steel fin tubes. This efficiency cuts water heating time by 25% (e.g., heating 100L of water from 20°C to 60°C in 30 minutes vs. 40 minutes with standard tubes), resulting in lower energy bills for residential users and reduced operational costs for commercial facilities (e.g., hotels, gyms).
Temperature Tolerance: Safely operates at 120°C working temperature (common in tankless water heaters) and 1.6MPa pressure, exceeding the requirements of most residential water heaters (which typically operate at 80-100°C and 0.8MPa). The 1020 steel core retains its strength at high temperatures, with a tensile strength of 420 MPa at 120°C—preventing tube expansion or deformation that can block water flow.
Anti-Scaling Property: The smooth, polished fin surface (Ra <0.8μm) reduces mineral deposition (e.g., calcium, magnesium) by 40% compared to rough-fin tubes. This is critical in hard water regions, where limescale buildup can insulate the fins and reduce heat transfer efficiency. The anti-scaling property extends maintenance intervals from 6 months to 12 months, reducing downtime for water heater servicing.
Residential gas water heaters (tank and tankless models), providing efficient hot water for households of 4-6 people.
Commercial electric hot water systems (e.g., in hotels, hospitals), supporting high hot water demand during peak hours (e.g., morning showers).
Solar water heating auxiliary coils, capturing additional heat from solar panels to reduce reliance on electric or gas heating.
Industrial process water preheaters (e.g., in food processing plants), preheating water to 50-60°C before it enters industrial boilers—saving energy and reducing boiler wear.
Yes, the 4m length is highly adaptable for standard water heater enclosures. For tank water heaters (50-200L capacity), the tube is typically coiled into a spiral shape (with a 200-300mm coil diameter) that fits inside the tank without occupying excess space. For tankless water heaters, it is bent into a U-shape (with 2-4 U-bends) to match the compact design of the heater. The tube’s flexibility (due to the 1020 steel core) allows for these modifications without compromising structural integrity.
In potable water applications (residential or commercial), the expected service life is >15 years—double the 7-year average of standard carbon steel fin tubes. This longevity is due to the stainless steel 304 fins (resisting rust) and the 1020 steel core (resisting corrosion from potable water). In hard water regions, annual descaling with a 10% vinegar solution (circulated through the tube for 1 hour) is recommended to remove limescale buildup and maintain heat transfer efficiency. For industrial applications (e.g., process water with chemicals), the service life is 10-12 years, depending on water chemistry.
No, the fin design minimizes radiant heat loss by 35% compared to smooth tubes, thanks to the closely spaced fins that trap a layer of insulating air. However, for outdoor installations (e.g., solar water heater coils), foam insulation (with a thickness of 10-15mm) is recommended to protect against extreme temperatures (e.g., freezing winters) and further reduce heat loss. The insulation should be rated for temperatures up to 150°C to avoid melting when the tube is operating at maximum temperature.
