How to identify the quality of aluminum-plastic composite pipe

1. Check the appearance of the product:

High-quality aluminum composite pipes generally have a smooth outer wall, and the trademark, specification, applicable temperature, and number of meters are clearly marked on the pipe wall. The manufacturer also prints the production number on the pipe wall to monitor the product quality at any time; the product is well packaged and packaged The various signs on it are also clear, and the manufacturer's name, address, telephone number, etc. are all printed in prominent positions. The fake and inferior products generally have rough outer walls, unclear or incomplete labels, simple packaging, and unknown factory addresses or telephone numbers.

2. The aluminum layer cannot be ignored:

A good aluminum-plastic composite pipe has welding at the overlap of the aluminum layer, the aluminum layer and the plastic layer are closely combined, and there is no delamination; while some fake and inferior products have no welding at the overlap of the aluminum layer, and some aluminum layers and plastic layers often Layered, not tight.
