Aluminum Coil Tubing Fuel Line 3/8"

Aluminum tubing size from 1/4 to 7/8 is available in-store,  make sure aluminum tube stock in a dry environment, aluminum alloy 1060 or 1070 as the active element, it is easy to occur chemical action with moisture in the air. So how to weld aluminum is a real idea.

 leakge test

  1. Filling with Ni gas (1.00Mpa), keep the pressure for at least 30 minutes,
  2. Checking the pressure gauge with decreasing or not. No leakage is accepted.
  3. Keep pressure in store about 24 hours before delivery
  4. Bending testing:
    Bending at 180
    0 by a 25mm bending radius, there is no visible crack.
  5. Flattening testing:
    Pressing tube to be flat (inner wall distance same as wall thickness), no visible crack to be found.
  6. Cleaning test:
    Clean the inner wall surface, without any pollution found, total impurity content remained 5~60mg/ m2

Processing technology

  • 1070 alloy aluminum tube is called a hot extruded aluminum tube.
  •  Raw material 1070 aluminum wire rod size 9.5mm, feeding in the hot extruded machinery.
  • Extrusion model and temperature higher 570 °C  aluminum half nearly melting
  • Aluminum tubing comes through a cold pure water tank to lower surface temperature.

Application:

  • Refrigerant tube in the HVAC industry
  • Air conditioner pipe for mini split line set
  • Automotive repair as fuel lines
  • Evaporator and condenser pipes
  • Gas stove connecting pipes

warranty
