Stainless steel finned tube

The finned tubes made of stainless steel tubes as base tubes with added fins are collectively referred to asStainless steel finned tubeIt is the main heat exchange element of finned tube heat exchangers.

The base tube and fins of stainless steel finned tubes are both made of stainless steel material, and commonly used corrosion-resistant stainless steel materials such as 304316L, 3103212205, etc. can be selected
Stainless steel finned tubeThe processing technology includes several commonly used forms of finned tubes, such as wound stainless steel finned tubes, high-frequency welded stainless steel finned tubes, serial stainless steel finned tubes, and laser welded stainless steel finned tubes
The distance between the stainless steel sheets of the wound type is generally above 4mm, and the thickness is below 0.3mm; The height of the film is generally 10mm, 12.5mm, 15mm and other commonly used specifications; Due to the limitations of processing technology, the root of the fins of the wound plate is often affectedForming wrinkles can lead to the accumulation of dust and high resistance, but it is easy to process, has low cost, and is suitable for air cooling or heating occasions with relatively clean gas quality;
High frequency weldingStainless steel finned tubeThe sheet spacing is generally above 4mm, the sheet thickness is above 0.8mm, and the sheet height is generally not more than the radius of the base pipe, which is suitable for processing. The welding rate of high-frequency welding is over 98% high, and the tube and fin are firmly bonded,Not easy to invert, easy to clean due to dust accumulation, suitable for harsh working environments such as flue gas waste heat recovery, high working temperatures, and large temperature differences;
The fin distance of laser welding fin tube can be smaller. Generally, when the thickness of the fin tube is 1mm, the fin distance can be 3mm, which is more advanced than the processing technology of high-frequency welding, and the heat exchange area per unit length is largerThe wing ratio is higher and the heat transfer effect is better.
String typeStainless steel finned tubeThe thickness of the base pipe generally does not exceed 1mm, making it easy to expand the pipe. The maximum diameter of the base pipe can only reach 16mm; the thickness of the sheet is generally 0.12-0.2mm, the sheet spacing is 2.0-3.5mm, and the heat exchange area ratio per unit length isThe medium inside the coiled tube and the string tube can only be clean water, while the outside of the tube is clean air. The required work environment is relatively high.
Stainless steel finned tubeThere are many structural forms, please contact the manufacturer for specific use and design, and design a suitable form according to the specific working conditions to achieve the best effect.
