Pin tube is a new type of strengthening heat transfer element, whose main advantages are: Firstly, regardless of the transverse flue gas or longitudinal flue gas, all needle extended surfaces are scoured by transverse flue gas turbulent, the airflow forms symmetric steady vortex and backflow region at the back of column of the needle rib, thermal boundary layer is constantly damaged and reformed, which make boundary layer of heat transfer surface thin, reduce thermal resistance to greatly improve the heat transfer coefficient. Secondly, du e to the needle rib of pin tube is a kind of cantilever structure, vwhich vibrates when impacted by airflow so it is difficult to accumulate soot, in addition, strong turbulent scour of flue gas makes pin tube heat transfer element has strong soot cleaning ability.
Based Tube Size:OD45-48(It can follow the client requirements)
Based Tube Length ≤14000mm
Pin Materials:Carbon Steel,Stainless Steel,Iron Steel.
Application:Oil/Gas Boiler,EGE,Waste Heat Recover
The pin tube has high heating surface features, for the flow gas in the needle tube group turbulence, so it can greatly improve the heat transfer coefficient. After using pin tube,it can save a lot of material and installation engineering, improve the economic performance. Products are widely used in industry, chemical industry, power plants, waste gas waste heat recovery unit of the vessel, as well as the air heater, air cooler, the cooling tower, water cooler, a variety of products such as water, oil heat exchanger.
