Product Details
Brand Name: | Lordfintube | Place of Origin: | China | Model Number: | F013 |
Certification: | Other, ISO | Application: | Heater Parts | Type: | Fin Tube |
Product Description
A smooth core tube is inserted into an aluminium tube and then fins are extruded out of the aluminium tube. Advantages: Bond to outer and inner tube removes the risk of loss of contact due to thermal stress, fins are more rigid, and the Core tube is extensively protected against corrosion by the aluminium sleeve.
As per type HY, but fins are serrated. Advantages: Higher heat transfer coefficient, for same pressure drop compared with HY fin.
Material Combinations:
- Core Tube: Carbon steels, low-alloy steels, stainless steels, brass, copper, copper-nickel alloys, aluminium bronze, nickel-alloys, as well as exotic grades. Core tubes with extremely thin wall materials can be applied.
- HYS Fin Tube Exterior Tube & Fins: Generally Aluminium (different grades available)
Fields of Application:
• petroleum, chemical and petrochemical industries
• natural gas treatment
• steel industry: blast furnace and converter cooling systems
• power generation: steam turbine exhaust condensing
– contact condensing with cooling of circulating condensate
– fossil and nuclear power plants
• air conditioning (freon, ammonia, propane)
• incineration of household refuse
• compressor coolers, etc.
Manufacturing Process:
A polished and deoiled base tube is set in an aluminium sleeve. The whole goes through the fin machine which consists of three spindles set at 120° each bearing a stack of plates. These plates, stacked in form and diameter first build the fin, then bond the outer and inner tubes together. In certain cases (high airspeed) the fins are serrated after the finning process so as to increase the heat transfer coefficient.
Advantages:
1) Thermal
The bonding of the outer and inner tubes removes the risk of loss of contact with the aluminium due to thermal stress.
Maximum operating temperature: 250° C. The transfer coefficient remains steady. Additionally, as the outer sleeve is continuous no electrolytic couple is created.
2) Mechanical
The fins are more rigid and stand the handling shocks better, compared to types "G" and "L".
