ASTM A179 AL Fin Extruded Finned Tube With L Type For Heat Exchanger
ASTM A179 Finned tube is a heat exchange element. In order to improve heat exchange efficiency， fins are usually added to the surface of ASTM A179 seamless heat exchange tubes to increase the outer surface area (or inner surface area) of the heat exchange tubes， thereby achieving the purpose of improving heat exchange efficiency. heat exchange efficiency.
ASTM A179， ASME SA179 steel pipe covers minimum wall thickness， seamless cold-drawn mild steel pipe for tubular heat exchangers， condensers， and similar heat transfer equipment.
Extruded finned tubes are bimetallic tubes whose outer aluminum surface is made into fins by cold plastic deformation.
Spiral solid finned tubes are made by helically winding a continuous strip of fins around the tube.

ASTM A179 covers minimum wall thickness seamless cold drawn mild carbon steel pipe for use in tubing， heat exchangers， condensers， and other heat transfer services. Seamless ASTM A 179 steel pipe is supplied and produced by cold drawn method. The chemical composition contains carbon， manganese， phosphorus and sulfur. Required tests: hardness test， flattening test， flaring test， flange test， hydrostatic test.
The ASTM A179 seamless carbon tube produced by TONG CHUANG GROUP has the following advantages: high dimensional accuracy， high strength， good corrosion resistance， and good finish. ASTM A179 pipe is delivered in the annealed， normalized， normalized and tempered condition. And also provide value-added manufacturing services: bevel end， black oil surface， galvanized surface treatment， anti-corrosion oil， machining.
Extruded finned tube is a type of heat exchanger tube that is formed by extruding aluminum or copper fins onto the surface of a steel or copper tube. During the manufacturing process， the aluminum or copper fins are first pressed onto the outside surface of the steel or copper tube， and then tightly compressed through a high-temperature extrusion process， resulting in a seamless integration of the steel tube and the fins.
Extruded finned tubes have several advantages over other types of heat exchanger tubes， including:
1.High thermal conductivity: The large contact area between the fins and the surface of the steel or copper tube allows for quick transfer of heat to the center of the tube， resulting in improved heat transfer efficiency for the heat exchanger.
2.High mechanical strength: The extrusion process creates a very strong bond between the fins and the surface of the steel or copper tube， resulting in improved mechanical strength and corrosion resistance.
3.Easy to clean: The large gaps between the fins on Extruded finned tubes make them easy to clean， which helps prevent blockages and contamination.
4.Extruded finned tubes are used in a variety of applications， including air conditioning and refrigeration equipment， automotive engine cooling systems， chemical and petrochemical equipment， boilers， and power generation equipment.
