The quality Anti-corrosion pipeline is a product that uses pe for hot dipping or ep (epoxy resin) for internal and external coating, and has excellent corrosion resistance. At the same time, the coating itself has good electrical insulation and will not cause electrical corrosion. What tests need to be done when the quality Anti-corrosion pipeline is accepted, let’s take a look next.

1. The quality Anti-corrosion pipeline has low water absorption, high mechanical strength and low friction coefficient, which can achieve the purpose of long-term use. It can also effectively prevent damage to plant roots and soil environmental stress. Convenient connection and easy maintenance.
2. Thickness measurement is to measure the coating thickness of the quality Anti-corrosion pipeline at any four points perpendicular to the circumference on any two cross-sections.
3. Appearance inspection is to inspect the appearance quality of the quality Anti-corrosion pipeline with the naked eye.
3. Bending test. The quality Anti-corrosion pipeline factory pointed out that this test is generally performed on a bending machine or a mold. It is worth noting that there is no filler in the pipe during the bending test, and the weld is located on the side of the main surface of the bend.
4. The pinhole experiment refers to the use of an electric spark leak detector to check the quality Anti-corrosion pipeline at the specified test voltage, and at the same time check for sparks.
5. Low temperature experiment refers to placing the test piece in a low temperature box, staying for one hour, and then placing it in a normal temperature environment. The acceptance of quality Anti-corrosion pipeline is mainly for thickness. At this time, special inspection tools can be used.
4. The flattening experiment is to place the test piece between two plates, and gradually compress it on the pressure testing machine until the distance between the two flat plates is four-fifths of the outer diameter of the test piece. The flattening is a quality Anti-corrosion pipeline weld vertical. In the direction of load application.
