Boiler component parts H square Fin Tube with ASME standard for heating transfer system

Product Introduction

H finned tube is called square finned tube, there are two types of H finned tube, one is a single tube, usually called square
finned tube, the other is a double tube, usually called rectangular finned tube. And according to customer requirements
manufacturing. Due to its rectangular shape, it provides a larger surface area than spiral finned tubes. Because of the larger surface area available, these finned tubes are primarily used in air heating applications to reduce the overall size of the equipment.

The fusion rate between the H-shaped finned tube and the steel tube is as high as 95% or more, the contact thermal resistance is small, and the thermal conductivity is good. Because the airflow between the heat exchange tube bundles is similar to the tandem flow characteristics, there is less dust accumulation on the heat exchange surface during operation, and the fins are more uniformly scoured. The effective utilization rate of the H-shaped fin expansion area is higher than that of the spiral finned tube, and the overall heat transfer efficiency It is about 10% higher than spiral finned tube bundle.

H-shaped finned tubes have a high area expansion rate, less dust accumulation, and high heat transfer efficiency. In the case of equivalent heat transfer capacity, the heat exchanger can occupy the smallest space, and can minimize high-grade materials (ie, pressure tubes) The amount of use, and more use of low-grade materials, (fins). For new engineering projects, the height of the heat exchanger arrangement can be reduced, the overall weight is greatly reduced, the load of the suspension system is reduced, and the overall cost is reduced; for the renovation project, as much heat exchange area as possible can be arranged in a limited space to reduce the exhaust temperature , Improve the efficiency of waste heat recovery or increase the maintenance space for easy maintenance.

Our products can be modified according to our customers' needs and the situation.we design and manufacture safe,reliable and efficient H-fin tubes.it  has also completed stand-alone product quality assurance systems.Production of H-fin tubes are with high heat transfer efficiency, they have flue gas resistance and are designed for a small space.

Specifications

1). Add the heat exchange area and reduce the number of tubes, also increase the fume flow section area to reduce the fume speed and abrasion.
2). H type fin tube can be made to double H type fin tube, high rigidness to fit long tube row.
3). H type fin economizer arranged in line to make the space into many small zones, averaged air flow to reduce the abrasion.
4). With straight channel to gain the best ash-blowing effect.
5). The compact structure to reduce the weight and reduce the manufacturing cost.
