ASTM A192 / A192M : Seamless Carbon Steel Boiler Tubes for High-Pressure Service
ASTM A210 / A210M : Seamless Medium-Carbon Steel Boiler and Superheater Tubes
Steel Grade: Grade A1; Grade C
Delivery Condition: Annealed, Normalized, Normalized and Tempered
Introduction:
The aluminum fin strip is tension wound and placed into a groove cut into the tube. The depth of this tube is about 0.4mm, and all the goods are Zinc or Aluminum metalized applied by an electro spray arc system coating on surface. The goods will be delivered when tube ends are square cut, free burrs, internally dried and air blown clean, externally coated with varnish at both ends of G-Fin Embedded Finned Tube. The desiccants are put into each package for continental transportation as well. Besides it applies to many areas such as 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. And we provide the tube support box, clamp or spacer box (Materials: Aluminum, Zinc and Stainless Steel).
Acceptance criteria:
API Standard 661(Air-Cooled Heat Exchangers for General Refinery Service) or the delivery conditions.
Specifications:
Grooved G type Finned Tubes are combined with two different materials.
