Product Description

This finned tube maximizes the performance of heat exchangers and minimizes the loss of heat transfer and pressure.

We are designing and manufacturing fin tube modules, economizers/heat exchangers and the suitable heating surface cleaning systems according to your requirements.

H fin tube known as square fin tube, there are two types of H fin tubes, one type with single tube, normal called square fin tube, the other with Double tube, normal called rectangular fin tubes. and also manufactured as per customers requirements. Due to rectangular shapes, which can offer large surface area compared to the Spiral Finned tubes. Due to larger surface area available, these finned tubes are used mostly in Air Heating application to reduce the overall size of the equipment.

H fin tube is a kind of boiler parts, which has two steel circular welded on base tubes to form fins positive shape much like letter “H”, so called H-fin tube. H-economizer widely used in utility boilers, industrial boilers, marine power, such as the tail of heat exchanger components.

• Max. Working Temperature: 300 °C
• Atmospheric Corrosion Resistance: OK
• Mechanical Resistance: Good
• Fin Material: Copper, Aluminum, carbon steel, stainless steel

Base Tube materials: Any material available, such as Carbon steel Tube, A179, A192, A210, stainless tube A269/A213 T5 T11 T22 304 316

Single pipe square finned tubes and twin pipe rectangular finned tubes are also manufactured as per customers’ requirements. These are particularly suitable for dust laden exhaust gases, e.g. for economizers in coal and oil fired units or waste incinerators.

Oval fin tube

All Kind of oval fin tubes material can be applied for this type of fins.

Fin spec can be changed follow with client requirement.

Applied Temperature: 850C(1593 F)

This is for Air Cooled Oil Cooled Heat Exchanger, Condenser, Heater in field of Oil Refinery, Petrochemical Industry Offshore and Power plants.

H Finned Tube

Sunny steel set up special type of finned tube include rectangular or square-shaped fins over oval tube.

H Finned Tube is divided into single H Finned Tube and Twin H Finned Tube (HH or Doule H finned tube), also known as Rectangular Finned Tubes. H Finned Tube is made by welding square or rectangular H fins to a steel base tube.

H Finned Tube economizer has two rectangular fins, similar to a square, its edge length for the fluorescent tubes of 2-fold, an expansion of the heating surface.

Rectangular Fins are welded on 2 steel base tubes. We call it HH or Doule H Fin Type Tubing.

HH Finned Tube economizer flash resistance welding processes used the welding seam after the high rate of fusion, weld tensile strength, and have good thermal conductivity. H-economizer can also manufacture dual tube “double H” type fin tubes, its rigid structure, and can be applied to a longer tube row occasion.

Twin H Finned Tube (HH or Doule H Finned Tube)

The fins are divided into two symmetrical halves, the tube wall is pressed from both sides, and the tube wall is welded by resistance welding, leaving a certain gap in the middle; two round tubes can share a set of fins, called Twin H Finned Tube

Single H Finned Tube

The fin is divided into two symmetrical halves, which press the tube wall from both sides, and are welded to the tube wall by resistance welding, leaving a certain gap in the middle; there is only one round tube in the middle, which is called Single H Finned Tube.

The heat exchanger composed of H-shaped finned tubes is closely arranged, and the tube bundles are arranged in a row.
