3003 Aluminum Internal Thread Aluminum Tubing Heat Transfer Arear
7mm
Product Description:
Efficient and corrosion-resistant aluminum tubing with internal
threading is a highly reliable and effective heat transfer element
that is ideal for use as condenser and evaporator flow pipes in
various refrigeration equipment. This product is primarily used
with refrigerants and other similar mediums. The unique threading
and high teeth on the inner surface greatly increase the heat
exchange area of the product, reducing reliance on refrigerant and
optimizing cost-effectiveness.
Key production specifications are currently available in finished
sizes of φ 9.52, φ 7.94, φ 7, φ 5, and other custom sizes available
upon request. The inner wall of the threaded pipe can also be oiled
according to specific customer requirements.
Crafted from aluminum alloy, this product takes on a silver
appearance and arrives in a coil tube format. All aspects of
production, from raw materials to finished product, are subject to
strict quality control standards in line with a robust quality
management system. This ensures that the end product provides
optimal stability and the highest levels of quality for our
customers.
Features:
Key features of the product include options for thin, high, low,
fine, and small tooth shapes to be customized in alignment with
customer needs. The tubing is available in two materials: 3003
anti-corrosion aluminum alloy as well as our highly efficient,
proprietary anti-corrosion aluminum alloy that exceeds the
anti-corrosion properties of 3003 aluminum alloy by ten fold.
When used in the evaporator, threaded aluminum tubing enables
strengthened heat transfer, resulting in an increase in heat
exchange area, the number of gasification cores, and degree of
liquid film turbulence. In the condenser, the tubing can boost the
heat exchange area within the tube, reducing the thickness of the
refrigerant liquid film between the tooth tops and the tank agent
due to the action of surface tension, which encourages the
condensant to leave the heat transfer surface.
