2. Check the appearance. Check whether the internal and external surfaces of the pipe are clean and smooth, free of grooves, paint, dents, impurities and uneven color.

3. Check the length. The length of the pipe should be uniform, and the error should not exceed ± 20mm. Check whether the nozzle end surface is perpendicular to the pipe axis and whether there are air holes. Before finding out the cause, all pipes of different lengths are not accepted.

4. Gas PE pipe shall be black. When black, the nozzle must have eye-catching color stripes. At the same time, the pipeline should have continuous and permanent marks with a spacing of not more than 2m, indicating the purpose, raw material brand, standard size ratio, specification size, standard code and number, manufacturer name or trademark, and production date.

5. Out-of-roundness inspection: take the arithmetic mean of the experimental results of three samples as the out-of-roundness of the pipe. If the value is greater than 5%, it is unqualified.

6. Inspection of pipe diameter and wall thickness. Use a round ruler to check the pipe diameter and measure the diameter of both ends of the pipe. Any unqualified place is considered unqualified. Use a micrometer to check the double thickness and measure the upper and lower four points of the circumference. The unqualified place cannot be used.
