Crimped Fins are spirally wrapped onto the base tube without welding, but spot welded at two ends. The steel strip can be copper, carbon steel, stainless steel. Non-ferrous tubes and fins on either root soldered or completely tinned.
Material Standard
Both base tube and fin can be copper, carbon steel and stainless steel
Carbon Steel: A179, A192,SA210 Gr A1/C,A106 Gr B
Stainless Steel: TP304/TP304L
Copper strip also available.
Maximum working temperature: 120°C
Our spiral crimped finned tubes is with base tubes of carbon steel, stainless steel, copper and copper alloys such as admiralty brass, aluminum brass with copper fins, staninless steel fins and zinc galvanized fins. The base tube of standard edge wound crimped fin tubes range from 15.875mm to 50.8mm with fin height ranging from 10mm to 15mm.
For this kind of crimped fin tubes, the fin pitch is around 5-6FPI. (large fin pitch than other aluminum fin types).
Below Chart of spiral crimped fin tubes dimensions for your reference.
Features
Uniform pitch
Small fold on fins
Tubes and fins are connected tightly
No ash accumulation
High heat transfer capability
Maximum working temperatures: 120°C
Since the stainless steel is with high corrsion resistance, the stainless steel crimped fin tube can be widely used when the circumstance has a certain degree of corrosion or cleanliness, such as climatic industry, heating, drying and cooling. Stainless steel tube with helical SS304 fins is widely applied in wood drying kilns to dry the woods.
