Mechanical Properties

Details

Manufacture: Tubes shall be made by the seamless process and shall be cold drawn.

Heat Treatment: Tubes shall be heat treated after the final cold draw pass at a temperature of 1200°F [650°C] or higher.

Surface Condition: Finished tubes shall be free of scale. A slight amount of oxidation will not be considered as scale.

Hardness Requirements: The tubes shall have a hardness number not exceeding 72 HRB.

Test Methods Referreds: Flattening Test, Flaring Test, Flange Test, Hardness Test, Hydrostatic Test,etc.

Keywords: Cold drawn tubes, Condenser tubes, Heat exchanger tubes, Low carbon tubes, Seamless tubes, Boiler tubes, etc.

ASTM A179 covers minimum-wall-thickness, seamless cold-drawn low-carbon steel tubes for tubular heat exchangers, condensers, and similar heat transfer apparatus.

Embedded G Finned Tubes

Embedded fin tubes, also known as integral fin tubes, are heat exchanger components where fins are mechanically embedded or bonded into grooves on the outer surface of the base tube. This creates a strong mechanical bond between the fins and the tube, enhancing heat transfer efficiency.

Processing technology: machining grooves into the outer surface of the base tube, then inserted fins into these grooves.

Base tubes are usually made of materials like carbon steel, stainless steel, or copper alloys. Fins can be made from aluminum, copper, or other high-conductivity materials to improve heat transfer.
Application:power generation, chemical processing, HVAC (Heating, Ventilation, and Air Conditioning), and refrigeration.

Advantages

1.Enhanced Heat Transfer

2.Durability

3.Versatility

However, the manufacturing process can be more expensive compared to other types of fin tubes. And the process of embedding fins requires precise machining and assembly, which can be complex and time-consuming.
