Welding Type Finned Tube for Gas Recovery (SHGG)

Descripition:

Welding type Finned Tube is made up by coiling band steel around plate fin and

Firmly soldering plate fin onto finned tube through using high-frequency welding

Process, which can ensure intensity of combination between finned tube and plate

Fin.



This welding type finned tube specification:

Tube material: Stainless Steel

Tube dimension: ¢ 18 mm

Fin material: Stainless Steel

Fin diameter: ¢ 38

Fin height: 10mm

Fin space: 3.5mm

Application:

In power plant, power plant modification, air conditioning & refrigeration, boiler

, finned type coal saver ( economiser ) and air preheater for heat recovery.


Other Tube Material including: Stainless Stee

Carbon Steel

SA210 A1

SA 213-T11

SA213 T22
SA213 T91

The fin diameter is very flexible, can be changed by customer different requirements
