How to detect the quality problems of three oil five cloth anti-corrosion steel pipes

1. Appearance inspection
The appearance inspection of three oil five cloth anti-corrosion steel pipes is a simple and intuitive detection method. When conducting an appearance inspection, it is necessary to carefully observe whether there are uneven surfaces on the pipe body and whether there are obvious defects such as bubbles, wrinkles, and sand holes. In addition, it is also necessary to check whether the thickness of the pipe body is uniform, whether there are problems at the joints, etc.

2. Magnetic particle inspection
Magnetic particle inspection is a commonly used non-destructive testing method that can be used to detect defects on the outer surface or inside of three oil five cloth anti-corrosion steel pipes. When conducting magnetic particle inspection, it is necessary to apply iron powder or magnetic powder on the outer surface or inside of the test pipe, and then apply a constant magnetic field during the test to observe whether there are defects such as cracks and bubbles on the surface or inside of the pipe body.

3. X-ray detection
X-ray detection is a very effective non-destructive testing method that can detect defects inside three oil five cloth anti-corrosion steel pipes, such as uneven material distribution and cracks. When conducting an X-ray inspection, a professional X-ray machine is required to detect defects on the surface of the X-ray tube. Since X-rays have certain radioactivity, protective measures should be taken when implementing X-ray inspection.

4. Water pressure test
The water pressure test is a commonly used hydrostatic test that can detect the sealing and pressure resistance of three-oil-five-cloth anti-corrosion steel pipes. When conducting a water pressure test, the test pipe needs to be placed in a water tank, and then a water pump or air compressor is used to increase the liquid or gas pressure in the pipe body to a certain value and observe whether there is leakage and deformation to ensure the pressure resistance of the pipe body.
