Detail Information

Manufactured in the same way as the "L" finned tube type except that the fin foot is overlapped to completely enclose the base tube thereby giving excellent corrosion resistance. This type of finned tube is often used as an alternative to the more expensive extruded type fin in corrosive environments.

Bare tube general material: Copper, Alloy, Carbon Steel, Stainless Steel.
Bare tube OD: 16-63mm.
Fin general material: Copper, Aluminum.
Fin pitch: 2.1-5.0mm.
Fin height: <17mm.
Fin thickness: 0.4mm.

LL-type finned tube:
LL-type finned tube makes the trapezoidal cross-section forming by rolling combine closely with the heat flux density distribution size. The fins combine tightly with the tube, which makes the thermal efficiency higher and put an end to thermal resistance that brings by the non eliminate contact from segment gap of the string type finned tube.
Working temperature: 230℃.

Features:
The winding technology improves production efficiency and heat transfer, makes the average fin pitch and higher proportion between fins and tube. At the same time, the base tube can be protected from air erosion.

Application:
LL-type finned tube mainly used in petrochemical, electric power, paper making, tobacco, building heating and other industry such as air cooler, air heater and air heater of food industry, plant starch spray drying system.
