About us

DELLOK (YONGHUI RADIATING PIPE MANUFACTURING CO.,LTD.) was established in 2002, which is located in Jiangsu, 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 -Production workshop- Meticulous works, standardized management system and systematic quality assurance are Dellok(YONGHUI)'s best commitment to quality. In Dellok(YONGHUI), the quality control is not only the detection of the final process, but throughout the entire production process. We implement a set of quality control and assurance systems. Each batch of pipes is sampled and tested, and records are kept as a quality guarantee for the final product.

^{Product Description:}

^{The Extruded Fin Tube also known as Bimetallic Fin Tube is one of
the most preferred finning processes for various applications.}

^{The fins are manufactured by Extruding the Fins on the Aluminum
Muff Tube which is made to Fit with close tolerance over the Base
Tube.}

^{The Extrusion takes place on a Continuous Fin Extruder with Three
Tooling rolls and extrusion takes place at high pressures in the
range of 1200 psi.}

^{Because of the cold working process the Bond between the Tube and
fin is flawless and hence gives excellent Heat Transfer Efficiency.}

^{At the same time the mechanical strength of the fins is also
enhanced drastically.}

Aluminum Extruded Tubing

^{Manufacturing Process:}

^{A carefully degreased core tube is fitted into an aluminium primary
tube.}

^{This assembly is then fed into the triple-spindle finning head of
the fin-extruding machine.}

^{Three special multi-disc packs extrude the aluminium tube into
helical high fins}

^{while reducing the inner diameter to give firm pressure contact
with the core tube}

^{Fin materials: Aluminium}

^{Base tube materials: Any metallic material}

Extruded Aluminum Tube

^Advantages:

^{1) Thermal}

^{The bonding of the outer and inner tubes removes the risk of loss
of contact}

^{with the aluminium due to thermal stress.}

^{Maximum operating temperature: 250°C. The transfer coeffcient
remains steady.}

^{Additionally as the outer sleeve is continuous no electrolytic
couple is created.}

^{2) Mechanical}

^{The fins are more rigid and stand the handling shocks
better,compared to types "G" an "L".}

Extruded Aluminum Tubing

^Properties:

^{To improve the heat transfer efficiency in the effective space.}

^{To Reduce the required installation space for the required heat
transfer surfaces.}

^{To lower equipment cost while having higher operational
reliability.}

^{The running cost is lowered due to lower tube side pressure drop.}

^{The rigidity of tube is increased, which improves the seismic
resistance of the tube.}

^{Enhancement of heat transfer, reduction on flow resistance and
metal consumption.}

Extruded Fin Tube

^{Applications:}

^{These Fin Tubes find application in AIR FIN COOLERS, DRIERS,
RADIATORS etc and are preferred}

^{in Industries like Food}

^{and Agriculture, Power Plants, Chemical Industries, Steel Plants,
Chiller Plants etc.}

FAQ

^{Q: What is your the lead time for production?}

^{A: Generally Sample needs 1-3 days, mass production needs 15-30
days,} ^{also depends on your request.}

^{Q: What is the warranty for your products?}

^{A :We provide one year warranty for the products.}

^{Q: What payment terms do you accept?}

^{A :Trade assurance,TT,Western Union.}

^{Q: What are the modes of transportation of machines?}

^{A: Air freight, sea freight express delivery, etc. We will choose
the most suitable transportation method according to}

^{your requirements.}
