Crimped Finned Tube For Heat Exchangers
Crimped Finned Tube, also known as Cold Raised Finned Tube, is to spirally wound crimped fins on the base tube without welding, but spot welding. Root welded or fully tinned non-ferrous tubes and fins.
 
The fins of the Crimped Finned Tube are crimped, which allows the Crimped Finned Tube to provide higher air side turbulence and heat transfer.

Manufacturing Process:
Crimped Finned Tube is a helically wound crimped fin on the base tube without welding, but spot welding. Root welded or fully tinned non-ferrous tubes and fins.
 
Quality Control for Crimped Finned Tube
The quality of the Crimped Finned Tube is assured by hydrostatic or pneumatic testing, eddy current testing and tensile testing to verify the mechanical bond between the inner and outer tubes.
 
 
Delivery conditions
The tube ends are square cut, free of burrs, dry and blown clean on the inside and varnished on the outside on both ends. Desiccant is also put into each package for continental shipping.
 
 
Application
U Bending Low Finned Tubes are widely used in environments with a certain degree of corrosion or cleanliness, such as climate industry, heating, drying and cooling.
 
 
Features of Crimped Finned Tube
Uniform pitch, small wrinkle, no dust accumulation
Small contact thermal resistance, strong heat transfer ability
Crimped Finned Tube can be further hot-dip galvanized to protect the surface, and the deposition of zinc also increases the efficiency of the finned tube. Maximum operating temperature 250°C.
Applications Commercial applications for air heating or air cooling up to 130°C to 150°C
