Answers To Common Questions About PPR Water Pipe Jet Coding And Cutting Surfaces

What does the jet code on the water pipe generally contain?

The surface of the PPR water pipe will generally have a series of jet code, composed of words and numbers. The spray code on the water pipe generally contains brand information, product specifications, industry standards, operation specifications, production date and other content.

Inkjet can erase, this is a normal phenomenon?

In order not to damage the surface of the pipe, generally we see the PRINTING words on the PPR pipe, are using environmental protection ink coding technology. The jet code is only attached to the surface of the pipe and will not penetrate or react with the material of the pipe. Due to the smooth surface of the pipe, the relevant content printed by ink printing code will fade or disappear with constant friction for a long time, which is a normal phenomenon and does not have any impact on the quality of the product itself.

White edge appears on the cut surface of water pipe. Is there any material problem?

PPR raw material, commonly known as random copolymer polypropylene, is a polymer. White edge after cutting is a unique property of plastic polymer, it refers to the polymer under tensile stress, in some weak places of the material stress concentration and local plastic deformation, known as the "silver phenomenon", after heating, the silver will disappear.
