ASTM A213 TP316L Longitudinal Welded Finned Tube For Petrochemical 

The ASTM A213 TP316L Longitudinal Welded Finned Tube is a high-efficiency enhanced heat transfer component manufactured using advanced welding technology, specifically designed for demanding petrochemical applications.

It consists of a TP316L austenitic stainless steel base tube and longitudinal continuous fins integrally formed through precision welding, offering outstanding heat transfer performance and exceptional corrosion resistance.

1.Chemical & Mechanical Properties

Mechanical Properties

2. Product Principle

Longitudinal finned tubes are produced by resistance welded fins along the length of the tube.
The fins first form a U-shaped channel, so that each U-shaped leg forms a fin. The channel is cut to the appropriate length, then oriented and resistance welded in place along the length of the tube. The channel is a pair of welded, opposite, so the number of fins specified must be a multiple of four.

3. Key Features

• Improve the heat transfer efficiency in the effective space;
• Reduce the installation space of the required heat transfer surface;
• At the same time, it has high reliability;
• The pressure drop on the tube side is reduced and the operation cost is reduced;
• The stiffness and seismic performance of steel pipe are improved;
• Heat transfer is strengthened to reduce flow resistance and metal consumption.
• Typical Service Conditions

      Temperature Range: -50°C ~ 450°C

      Pressure Rating: Class 150 ~ Class 900

      Media Types: Crude oil, hydrocarbons, acid gases, organic solvents, etc.
