Aluminium Spiral Fin Tube

How does a Spiral Fin Tube is manufactured? Or how is the Spiral Fin Tube different from any other finned tubes in your factory? You may asked.

To answer the question, Our Spiral Fin Tube, also accepted by the name of Low Fin or Fin and Tube, is of simple and stable structure. First, we need to mold a collection of hollow tubes, or bare tubes. After that, our engineers will operate the machinery so that the tubes would be rolled with metal strip to form a Spiral Shape. In the final procedure, we’ll have to polish the tubes a little bit and then we’ll have what we called Spiral Fin Tube, also known as Fin and Tube, Low Fin.

Categorization of Spiral Fin Tube

Mostly, our Spiral Fin Tube and Low Fin will be divided into three types in accordance with the slightly difference in their constructions.

	L Type Spiral Fin Tube	LL Type Spiral Fin Tube	KL Type Spiral  Finned Tube
Structure
Temperature	230Degree	170Degree	≤250Degree, Pressure: ≤3.2MPa.
Applications	Mainly used in air coolers  and air heat exchanger for petrochemicals,power,paper making, tobacco, building heating, and air  heater for spray drying system such as vegetable protein powder and starch in food industry.	LL type spiral wound finned tube:on the basis of L-type,the root of the fin is completely covered on the outer surface of the base tube, which can strengthen the contact surface and increase the heat transfer effect.	1.High heat transfer performance and low contact thermal resistance; 2.The contact area between the fin and the tube is large,and the joint is tight and reliable; 3.It has good atmospheric corrosion resistance and stable long-term service performance.

Application for Low Fin or Fin and Tube

This type of Finned Tube is widely used in the drying in the industries of chemical, textile printing and drying, chemical fiber, latex, lather, timber, metallurgy coating, feed, lamination machine and others.

FAQ about Low Fin or Fin and Tube
