ASTM A179 A179 CARBON STEEL EMBEDDED FIN TUBE PLAIN END
Description:
G-type fin tube is a type of heat exchanger that is commonly used in various industrial applications. It consists of a base tube with extended fins， which greatly increases the surface area of the tube and allows for more efficient heat transfer between fluids.
The embedded fin design offers several advantages over other types of finned tubes. It provides a strong mechanical bond between the fins and the tube， which makes it more resistant to damage from external forces such as vibrations and impacts. The embedded fins are also less likely to loosen or detach from the tube over time， which can occur with other types of finned tubes.
Embedded finned tubes are commonly used in heat exchangers for applications such as power generation， chemical processing， and HVAC systems， where high heat transfer rates are required. They can be manufactured using a variety of materials， such as carbon steel， stainless steel， copper， and aluminum， depending on the specific requirements of the application.
Manufacturing Process
Embedded finned tube is a type of finned tube where the fins are made by embedding a strip of metal into the outer surface of the tube. The metal strip is usually made of aluminum or copper and has a series of fins attached to it. The strip is then inserted into a groove that is machined into the outer surface of the tube and the groove is then filled with a high-temperature alloy， typically an aluminum or copper alloy.
