Product Description
DELLOK ASTM Carbon Steel U-Shaped Longitudinal Finned Tube
DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) specializes in high-performance longitudinal finned tubes designed for optimal heat transfer efficiency in industrial applications.
Product Overview
Our U-shaped longitudinal finned tubes feature channels welded to the external tube surface using advanced resistance weld technology. Each fin strip is shaped into a U-form, creating efficient heat transfer surfaces with fins always in multiples of four.
Key Performance Advantages
- Heat transfer area increased by 8 to 12 times compared to bare tubes
- Superior heat transfer efficiency for enhanced performance
- Compact design reduces required exchanger size
- Cost-effective solution for industrial applications
- Fins can be cut or twisted to increase fluid turbulence and improve heat transfer

Frequently Asked Questions
What Are Finned Tubes Used For?
Finned tubes are particularly effective in air heat exchangers where heat transfer occurs between liquids and gases. The increased surface area significantly enhances heat transfer efficiency.
What is a Longitudinal Finned Tube?
Longitudinal finned tubes, also known as Brown Fintubes, are manufactured using high-frequency resistance welding to attach fins along the length of the tubes.
What are the Key Properties of Longitudinal Finned Tubes?
These tubes improve heat transfer efficiency in compact spaces, reduce installation requirements, lower equipment costs, enhance operational reliability, and improve seismic performance.
