Seamless Densities Segment Fins Alu1050 Extruded Fin Tube
seamless cold finished mechanical extruded bimetallic finned tubes
We have fourteen extrusion fining lines, daily capacity around 15,000 meters, max. base tube OD 2''
Detail:
ASTM A192 / A192M : Seamless Carbon Steel Boiler Tubes for High-Pressure Service
ASTM A210 / A210M : Seamless Medium-Carbon Steel Boiler and Superheater Tubes
ASTM A179 / A179M : Seamless Cold-Drawn Low-Carbon Steel Heat-Exchanger and Condenser Tubes
Tube Type: Seamless (Cold Drawn)
Ends: Plain ends or bevel ends.
Surface protection:black painting,anti-rust oil or varnish.
Introduction:
A smooth core tube is inserted into an aluminum sleeve and then the fins are extruded out of the aluminum sleeve. The fins are solid plain or serrated into 12, 16 or 24 segments or as your design. And both plain ends with appr. 10mm~50mm and gaps (Unfinned Section) in the middle. All the goods shall be Zinc or Aluminum that metallized applied by an electro spray arc system coating on surface. Besides, we provide Tube Support Box, Clamp or Spacer Box(Materials: Aluminum, Zinc or Stainless Steel).
Applications:
The common application fileds are:
Heat exchangers units for power plant (electric, nuclear, thermal and geothermal power plants);
High corrosive systems (condensers, evaporators, sea water desalinations, fertilizing, urea systems, ammonia, gas, corrosive acids);
The petroleum, chemical and petrochemical industries;
The food processing and refrigeration industries;
Natural gas treatment;
