DELLOK High Frequency Stainless Steel Longitudinal Fin Tube Welded

^{DELLOK High Frequency Welded Stainless Steel Longitudinal Fin Tube}

^{About Us}

^{Dellok(YONGHUI Radiating Pipe Manufacturing Co.,Ltd) was
established in 2002, which is located in Nanjing, China.We joined
HARBIN AIR CONDITIONING CO., LTD. in 2022 and became the most
professional industry manufacturer in China. After many years of
development, the company now has 66 million yuan in fixed assets,
more than 200 employees, and 33 technical staffs. We have 4
aluminum processing production lines, with the annual processing
capacity of more than 20,000 tons; And we have 5 tube-drawing
production lines; 47 fintube production lines, 1 imported
production line from American with the brand of McElroy , with the
annual production capacity of 12 million meters the above.}

^{Quality is the theme of eternal pursuit of winner.}

^{Longitudinal
Finned Tube Product Description:}

^{Finned tubes (or finned pipe) are produced by resistance welding
fins in diametrically opposite pairs. The way channels are welded
on the external surface of the tube makes them highly efficient.}

^{They are formed from a U channel of material, with the base being
pressure rolled and spot welded to the tube or pipe. The number of
fins must always be a multiple of four.}

^{All our finned tubes can be manufactured from most weldable or
brazable materials. The finned pipe is supplied in straight lengths
or U bent form.}

^{Longitudinal Fin Tube Manufacturing Process:}

^{The longitudinal fin tubes are welded onto the core plain tubes by
resistance welding or welding with filler metal.}

^{Longitudinal
Fin Tube(Carbon
Steel Welded Pipe) Advantages:}

^{Provide 8 to 12 times the heat transfer area of bare tubes.}

^{Are more efficient than bare tubes.}

^{Provide smaller exchangers due to increased Heat Transfer area.}

^{Often provide a more economical selection.}

^{Fins can be "Cut & Twist" to increase shell side fluid turbulence
and improve heat transfer.}

^{Brown
Fin Tube Properties:}

^{Improve heat transfer efficiency in efficient space.}

^{Reduces installation space on required heat transfer surfaces.}

^{Reduce the cost of the equipment, and have a high operational
reliability.}

^{The pressure drop on the side of the tube is reduced and the
operation cost is reduced.}

^{The stiffness of steel tube is improved, and the seismic
performance of steel tube is improved.}

^{Enhance heat transfer, reduce flow resistance and metal
consumption.}

^{Longitudinal Finned Tube(Welded
Steel Pipe) Applications:}

^{We supply longitudinal finned tubes for:}

^{double pipe heat exchangers}

^{multi-tube heat exchangers}

^{fire rated heaters}

^{gas coolers}

^{tank heaters}

^{And we are able to accommodate the requirements of various
industries, including oil, power, chemical, and petrochemical.}
