Aluminum Coil Tubing Fuel Line 3/8"

We are a manufacturer of Aluminum Coil Tubing Fuel Line 1/4,3/8,1/2,5/8 and 3/4

Widely used in the automotive and air conditioning industry as important HVAC parts.

 Features:

• Material alloy grade:1050.1060,1070
• Temper: O and H14
• Thin wall aluminum tubing
• length: 10ft,20ft,25ft,20ft,50ft etc
• max working pressure:4.0Mpa

Technical parameter:

• Processing：Hot extruded
• Pipe Tensible strength: 68-80Mpa
• Tube Elongation: 30-40%
• Bursting pressure > 1800 PSI
• Bending at 180⁰ by 25mm bending radius: no visible crack.
• Surface quality: smooth, no crack

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 180⁰ 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
