Product Description:
The 3003 aluminum pipe is highly efficient and possesses
corrosion-resistant properties. It is a seamless steel pipe with a
spiral inner wall that retains the nuclear boiling state under high
heat loads. This prevents film boiling and ensures durability. The
pipe is suitable for use in condenser and evaporator flow tubes of
various refrigeration equipment. The primary media used in the
pipeline are refrigerants. Compared to smooth tubes, the inner
threaded aluminum pipe has a larger internal surface area, enabling
efficient heat exchange when coolant flows through the tube. This
feature makes it increasingly popular over time.
The product is available in different specifications, including Φ
9.52, Φ 7.94, Φ 7, and Φ 5 finished products. We customize the
specifications and performance requirements according to customer
requests and can oil the inner wall of the threaded pipe to meet
the requirements of the rear road riser process products. The basic
production method of internal threads is to lighten the wall
thickness while generating threads within the tube along the thread
direction on the mandrel, thereby improving pipe diameter
reduction.
Features:
The product has various tooth shapes, such as thin wall, high
tooth, low tooth, fine tooth, and small teeth, that can be
customized based on specific requirements.
Our unique high-efficiency anti-corrosion aluminum alloy is used to
improve the anti-corrosion effect of this product, which is ten
times better than that of a standard 3003 aluminum alloy. Threaded
aluminum tubes can enhance heat transfer in the evaporator by
increasing the heat transfer area, number of gasification cores,
and turbulence of liquid film. In the condenser, the threaded
aluminum tube improves heat transfer efficiency.
