Brass Tubing (Brass Tube,Brass Pipe)
Application
  • Description

    Brass tubing is a kind of non-ferrous metal pipes. It is a seamless pipe through pressing and drawing. With the corrosion resistance character, copper pipe has become the first choice for modern contractors when installing tap water pipes, heating pipes and cooling pipes in all residential commodity houses. Brass pipe is the best pipe for water supply. Brass tubing can be classified into brass tubing for electric appliance, refrigeration, high pressure resistance brass pipe, corrosion-resistant brass tube, as well as brass tubing for connector, water channel, electric heating brass tubing and industrial brass tubing.

    Applications

    Our brass tubing is widely applied in Radiator Brass Tubing, Brass Condenser Tubing and Cooler Tubing.

    Features

    1. Light weight and excellent heat conductivity.
    2. Abrasion resistance and corrosion resistance.
    3. Applicable under high pressure and high temperature.
