Visual method: High quality aluminum-plastic tube color/Spray Code uniformity, no chromatic aberration, roundness less than 0.1; the middle aluminum layer interface is tight, no rough traces, smooth/smooth inside and outside surface, can not have obvious scratches/sag/bubble/dead material/converge line.

Touch method: Take a section of aluminum-plastic pipe square vertical cut, with a finger into the tube, high-quality pipe mouth smooth, no texture feeling;

Contrast method:

1, raw material comparison, at present, the domestic market high-quality aluminum-plastic composite pipe PE materials are from abroad, such as the United States, South Korea, if the raw materials from recycling materials can not be guaranteed.
