ASTM A213 Alloy Stainless Steel T9 Welding Studded Finned Tube for Heat Exchanger
Studded finned tube refers to a type of heat exchanger tube that has metal studs or fins attached to its outer surface. The purpose of studded fins is to increase the surface area of the tube， which in turn enhances heat transfer efficiency.
This design of this type finned tube is often used in applications where maximum heat transfer is required， such as in boilers， air conditioning systems， and industrial processes. Studded fin tubes are commonly made from materials like carbon steel， stainless steel， or aluminum.
TONG CHUANG Group offers welding studded finned tube of many materiales and we sell this type of fin tubes in over 70 countries.This type of finned tube has excellent enhanced heat creation effect， reduces heat transfer resistance， and improves heat transfer coefficient.
