Plastic Balls Manufacturer Introduces The Distinguishing Knowledge Of The Pros And Cons Of Pe Pipes

Plastic Balls Manufacturer introduces how to distinguish the advantages and disadvantages of PE pipes:

1. AppearanceHigh quality: The inner and outer surfaces of the pipeline are smooth, free of defects such as bubbles, dents and impurities.Poor quality: The inner and outer surfaces of the tube are not smooth, non-luminous, a bit corroded, and the inner and outer surfaces are obviously concave.

2. Milling strips: When manufacturing products produced with qualified raw materials, the strips cut by the welder should be bright in color and not easy to break after repeated folding. The whitening of milling strips or the appearance of other colors are caused by the addition of recycled materials or uneven mixing of raw materials.High quality: shiny, smooth, not easy to break after repeated folding.Inferior quality: The color is dark, easy to break after folding.

3. Welding joint: A qualified welded joint should have smooth and symmetrical flanges on the entire circumference of the pipe, and the minimum depth of the flange shall not be lower than the surface of the pipe; any outer edge on both sides of the weld is close to the flange The misalignment should not exceed 10% of the thickness of the pipe wall; the flange should be firm and smooth, with a wide root. There should be no impurities, small holes, deformation or damage under the flanging.High quality: smooth and flat flanging. After crimping the seam, the flanging may be longer.Poor quality: a large number of holes are formed on the surface after flanging. Folds after the seam pressure is too short.

4. SmellHigh quality: The product that has just been processed or heated and melted has a slight plastic aroma, and the product after cooling has no peculiar smell.Poor quality: pungent odor.

5. Burning flameHigh quality: stable burning and melting, the bottom of the flame is light blue, no peculiar smell.Poor quality: unstable combustion, irregular droplets, a small amount of black smoke and peculiar smell.

6. Elongation at break: Elongation at break refers to the ratio of the length of the sample at break to the original length. The higher the elongation at break, the softer the product and the better the performance.High quality: stretched to 3.5 times without breaking.Inferior: Elongation is easy to fracture, and toughness is poor.

 7. Oxidation induction time: Oxidation induction time is the time to determine the autocatalytic oxidation reaction of the sample under high temperature oxygen conditions. It is an index to evaluate the heat-resistant degradation ability of the material in molding, storage, welding and use. The longer the oxidation induction time, the better the aging resistance and the better the product performance.
