Bimetallic Finned Tube

BIMETALLIC Finned Tube

Bimetallic finned tube refers to a heat transfer tube with alternation of two (or more) different types of the fin. Its outstanding feature is that it can integrate the advantages of different heat transfer enhancement from the same fin to obtain better comprehensive performance. The bimetallic finned tube is consist of a base tube and wrapped fins. The base tube material usually comes as carbon steel, stainless steel or copper, and the aluminum pipe is outer core, then the aluminum pipe is continuously extruded into fins by a special rolling machine. Meanwhile, a thin under layer is formed and tightly wrapped on the outside of the base tube.

ADVANTAGES

The main advantages of the bimetallic finned tube are: the base pipe is a steel pipe, which has good mechanical properties, temperature resistance, pressure resistance and corrosion resistance; the outer core material is aluminum, light weight, low price, easy processing, and good Anti-atmospheric corrosion resistance, beautiful appearance; high fin strength, can withstand high pressure washing and descaling; generally it does not increase the contact thermal resistance due to corrosion and oxidation of the base tube, and the heat transfer performance is slightly better than the tension-wound finned tubes. The bimetallic finned tube is more and more popular, especially in large scale applications in the refining, chemical and power generation industries.

FAQ

Q1.What is the referenced codes and standards?

API661

Material Requisition, drawings or Technical Agreement

Q2.How do you pack the products

A: Each package is designed and made according to seaworthy packing standard and clients’ handling and lifting capability.

Finned tubes will be packed into steel frameworks and wrapped with weather proof PE film and plywood board covering up. In addition, each row of finned tubes will be isolated from adjacent with EPE(Expandable Polyethylene) foam to prevent rigid impact during transportation. For all exporting packages, we only use plywood instead of wood for fumigation free purpose.

Q3:How do you guarantee the quality?

A: we are ISO certified company and we maintain strict controls according to our specific written procedures and client specifications during all phases of manufacturing of our products ensuring full materials traceability and top quality. Besides, inspection activities carried out by world reputable third party such as TÜV, BV, SGS, Lloyd's, ABS, Intertek(Moody) etc. is available on call.

Q4:Do you have design capability?

A: Yes, we could develop the shop drawings and submit for clients’ approval.

Q4:How do you handle the documentation?
