What is pert pipe lined with oxygen-resistant aluminum alloy?

What is PERT pipe lined with oxygen-resistant aluminum alloy? ? Oxygen-resistant aluminum alloy lined PE-RT pipe is aluminum alloy lined plastic PERT composite pipe. The folding standard CJ/T32 1-20 10 aluminum alloy lined plastic composite pipe and its accessories are double-layer PERT composite pipes. The outer aluminum pipe is aluminum alloy 6063 grade deformed aluminum, and the inner plastic pipe is PERT pipe, which is made of aluminum alloy lined plastic pe-rt composite pipe by prestress.

The overall service (design) coefficient of PERT pipe lined with oxygen-resistant aluminum alloy is C≥ 1.5. The dimensionless value of s is 4, and s = (dn-en)/2en? Dn is the outside diameter of the pipe? En is the thickness of pipe wall; S=2SDR+ 1？ SDR standard size ratio SDR=dn/en. This means that the internal thermoplastic pert tube is SDR9/S4 series. The outer layer of aluminum alloy lined PE-RT composite pipe is 6063 brand modified aluminum, and the surface film of aluminum alloy pipe is required to be above 10um, the pressure of pert composite pipe is not greater than 2.5MPa, and the nominal diameter is not greater than dn 160mm.

? Application scope of PERT pipe lined with aluminum alloy for oxygen barrier

1, cold and hot water piping system, riser and horizontal pipe hoisting light and dark pipes;

2. Domestic water supply, domestic hot water and drinking water purification system for civil buildings and industrial buildings with working pressure not greater than 1.6MPa;

3. Low-heat solar energy heating? Piping systems, such as air energy and cooling devices;

4. Heating pipes, public hot water systems, etc.

5. Hotels, hospitals, schools, airports, high-speed railway station, etc
