Do you know the PPR pipe visual defect inspection ?

Visual defect inspection is an important part of quality control in the manufacturing process of PPR pipes. Detecting visual defects ensures that the pipes meet the required standards and specifications. Here are some common visual defects that may be inspected during the manufacturing of PPR pipes:

Surface Irregularities:

Inspectors look for any irregularities on the surface of the PPR pipes, such as scratches, dents, or deformities. A smooth and uniform surface is essential for proper functioning and longevity of the pipes.

Color Consistency:

PPR pipes are often produced in specific colors, especially for indicating hot or cold water lines. Inspectors check for color consistency and uniformity throughout the length of the pipe.

Dimensional Accuracy:

The dimensions of the PPR pipes, including diameter and wall thickness, must conform to the specified standards. Visual inspection includes checking for any deviations from the required dimensions.

Print and Marking Quality:

If the PPR pipes are marked with information such as size, brand, or standards compliance, inspectors ensure that the printing is clear, accurate, and durable.

Surface Smoothness:

The inner and outer surfaces of PPR pipes should be smooth to allow for efficient water flow. Any roughness or irregularities that could impede flow should be identified during visual inspection.

Joint Quality:

If the pipes are designed for use with heat fusion welding, inspectors may check the quality of the joints. This involves ensuring that the pipe ends are properly formed and free from defects that could affect the integrity of the joint.

Bending and Straightness:

PPR pipes should be straight, and their shape should conform to the specified standards. Inspectors may check for any bending or warping that could affect the installation and performance of the pipes.

End Cut Quality:

The ends of the PPR pipes should be cut cleanly and squarely. Visual inspection includes checking for any burrs or uneven cuts that could impact the fitting of pipes during installation.

Foreign Particles:

Inspectors look for any foreign particles or impurities that may be present on or inside the PPR pipes. Cleanliness is crucial to prevent clogging and ensure the pipes’ functionality.

Packaging Integrity:

The condition of the packaging is also inspected to ensure that the pipes are adequately protected during transportation and storage.

Manufacturers may use visual inspection alongside other quality control measures, such as dimensional measurements, material testing, and pressure testing, to ensure that PPR pipes meet the required standards and specifications before they are shipped to customers.

Advance Inspection Device can automatically help your extrusion production lines with 24/7 full inspection and 360-degree inspection. Originally, you need to judge the product surface defects by hand or eyes, which is time-consuming, laborious and poorly executed, and the quality and accuracy of the inspection cannot be guaranteed. However, with artificial intelligence technology, Advance™ inspection machine can help you monitor the product condition completely. The real time, production line position, character size（LH）of the surface defects can be displayed on the screen monitor, allowing operators to set up and control the quality of the Aluminum Plastic pipe production condition before poor Aluminum Plastic pipe with defects causes expensive waste. Usually, the production line needs 2 operators to monitor the condition of the product, while with Advance Machine 1 operators can monitor 2 production lines at the same time, which reduce the 75% human cost.
