G Type Fin Tube| Embedded Finned Tube

G Fin Tube discription: The fin strip is wound into a mechanically produced groove and tightened by backfilling of the base material under pressure.

Groove depth appr. 0,4 mm.

Advantages: High fin stability, excellent heat transfer, high operating temperature.

G Type Fin Tube Material Combinations

G Fin Tube Core Tube: Carbon steels, low-alloy steels, stainless steels, brass,copper, copper-nickel alloys, aluminium bronze, nickel-alloys (Alloy 400, etc.), bimetal, titanium and others

G Fin Tube Fins: Aluminium / Copper / Steel / Galvanized Steel

G Type Fin Tube Fields of Application:

• the petroleum, chemical and petrochemical industries

• natural gas treatment

• the steel industry: blast furnace and converter 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, ect.

G Type Fin Tube Manufacturing Process

The manufacturing tool is made up of 2 non-cutting plates set at 90° to the axis of the base tube. The first plate effects a groove for metal spinning. The second directs the ribbon in the groove and sets the fin foot in the groove through pressure on the metal displaced for the groove. A similar plate made of tungsten carbure allows us to manufacture G finned tubes with base tubes made of austenitic steel or exotic alloys.

G Type Fin Tube Advantages

1) G Fin Tube Thermal

The fin/tube wall contact is constant because of the setting and makes it possible to use a wall temperature of up to 400° C.

2) G Fin Tube Mechanical

The fin is set throughout its length and consequently does not unwind even when partially uprooted.

What is tube sheet layout?

What is tube sheet layout? A tube sheet is a component used in shell and tube heat exchangers and other types of heat transfer equipment. It is a flat plate with holes drilled in it, through which tubes are inserted and secured. The tube sheet serves as a barrier between the two fluids, allowing heat to be transferred from one to the other. The layout of the tube sheet depends on the design of the heat exchanger, which includes the number of tubes, the size of the tubes, and the spacing between the tubes. The layout is typically determined using computer-aided design (CAD) software, which can optimize the placement of the tubes to achieve the desired heat transfer performance. In general, the tubes are arranged in a triangular or square pattern on the tube sheet. The triangular pattern is often preferred because it provides better support for the tubes and reduces the risk of vibration and damage. The spacing between the tubes is also important, as it affects the flow rate and pressure

Finned tube bundle|Finned pipe bundle

1. What is a finned tube bundle? Finned tube bundle composed of multiple finned tubes arranged according to certain rules is called finned tube bundle. A finned tube heat exchanger can be composed of one or more finned tube bundles. 2. What is the composition of the finned tube bundle? Finned tube (multiple tubes): basic element of heat transfer. Tube box (header) or tube plate: the header, elbow or steel plate connecting the two ends of the fin tube. When the finned tube is connected with the header or tube sheet, the spacing between the finned tubes is fixed, and the tube box forms a continuous flow channel for the fluid in the tube. Frame: support and fix the whole finned tube bundle. 3. Finned tube bundle arrangement? In a finned tubes bundle , the selection of fin tube arrangement is crucial. There are two types of arrangement: staggered and sequential. The so-called staggered arrangement refers to the cross arrangement of pipes in the air flow direction, while the in-line arran

What is heat exchange tube sheet?

What is heat exchange tube sheet? A heat exchange tube sheet is a component used in heat exchangers, which are devices that transfer heat from one fluid to another. The tube sheet is typically a flat, circular plate that separates the two fluid streams and contains holes through which the heat exchange tubes pass. The tubes are typically sealed into the tube sheet by welding or expansion, and the sheet is often made of materials such as carbon steel, stainless steel, or titanium. The purpose of the tube sheet is to provide a rigid support structure for the heat exchange tubes and to ensure that the tubes are properly aligned and spaced for efficient heat transfer. The tube sheet also serves to contain the fluid streams and prevent them from mixing, which could reduce the efficiency of the heat exchange process. Tube sheets can be designed for various types of heat exchangers, such as shell and tube, double pipe, and plate heat exchangers. The design of the tube sheet is typically based
