Transition Nozzels

Transition nozzles, also named swage nozzles, is used as a component for industrial air fin fan cooler and plays an important part to convey heat energy between heat sources and working fluids.

The characteristics of transition nozzles for fin fan cooler

Bottom part is slot structure

Top part is round shape (OD stays same as material round pipe before pressing)

This design of transition nozzles can reduce header size and reduce the size of air fin fan cooler that applied in petrochemical plants, power plants and oil refineries.

Materials of transition nozzles

Available if various kind of materials, such as carbon steel pipe, chrome alloy, high nickel alloy, stainless and titanium.

Manufacture method of transition nozzles

Cold forming with special mold and then with heat treatment applied

Dimension of the transition nozzles:

6’’~18’’, Sch 40~Sch 160

Air fin cooled heat exchanger

Air fin fan cooler

Materials are supplied under the requirements of ASME Sec II Part B Edition 2021.

All Transition nozzles are plain-end beveled.

Reconditioning or repair of transition nozzles by welding is not permitted.

All transition nozzles are free of surface defects and have a clean finish.

100% PMI (Positive Material Identification) is required on Transition Nozzles for chemical components test.

The pipe used to form transition nozzle will have a hydro static test.

The finished individual transition nozzles can have legible marking as customized. (The legible marking is used as traceability). If customer don’t need it, it is OK without marking on transition nozzles surfaces.

When interested in our transition nozzles, have a glance at our aluminum fin tube also. Maybe we can supply you a full spare parts for making the air fin fan cooler.
