Extruded fin tubes ( finned tubes )
fin type: extruded fin tubes and many special sizes extruded fin
tubes ( finned tubes ). extruded fin tubes ( finned tubes ) has the
advantages of high efficiency, strong corrosion resistant and long
life as the International, technologically advanced heat transfer
element. The base tubes (pipes) (core tube) of double extruded fin
tubes can be SS, CS, corrosion resistant steel, copper and copper
alloys, Ti and Ti alloys and the other materials. The base tubes
(pipes) (core tube) of single extruded fin tubes can be copper,
Nickel-copper, Aluminum and the other materials. These products are
widely used in petroleum, chemical, metallurgy, textile, mechanical
and electrical, light industry and pharmaceutical industries in the
heating, drying, condensation and cooling equipments. Applications
and characteristics
Working temperature ≤**0°C
working pressure ≤*2MPa
High heat transfer performance, same with KL type (Knurled "L").
Good fins stiffness, against deformation high atmospheric corrosion
resistance for long term stable usage.
TECHNIFIN TYPE HY
A smooth core tubes (pipes) is inserted into an aluminum tubes
(pipes) and then fins are
extrudes out of the aluminum tube. Advantages: Bond ot outer and
inner tube
removes the risk of loss of contact due to thermal stress, fins are
more rigid,
also available as serrated type TECHNIFIN HYS see below.
TECHNIFIN TYPE HYS
As per type HY, but fins are serrated. Advantages: Higher heat
transfer coefficient,
for same pressure drop compared with HY fin.
