Thin-walled stainless steel pipe wall thickness detection method

Thin-walled stainless steel pipe wall thickness detection method Now there are many thin-walled stainless steel pipes on the market whose label thickness is different from the actual thickness, especially the label thickness of each manufacturer is different, which also leads to many consumers being confused about the actual thickness of the steel pipe. Different manufacturers, different materials, different batches, and different furnace numbers are all causes of pipe wall thickness deviation, so when we apply it, we cannot completely rely on the thickness on the label. We should measure the actual thickness according to actual needs. Then, let’s take you to understand the thin-walled stainless steel pipe wall thickness detection method. 1. The wall thickness measuring instrument measures the thickness based on the principle of ultrasonic pulse reflection. When the ultrasonic pulse emitted by the probe passes through the object to be measured and reaches the material interface, the pulse is reflected back to the probe to determine the thickness of the material to be measured by accurately measuring the time it takes for the ultrasonic wave to propagate in the material. 2. Wall thickness micrometer, its principle is to use the principle of spiral pair to read the distance between the spherical measuring surface and the flat measuring surface on the arc scale frame. It is a measuring instrument for measuring the wall thickness of thin-walled stainless steel pipes. Micrometers are generally more accurate when measuring the thickness of raw materials. We use micrometers when testing raw materials. 3. Vernier calipers can also measure the thickness of stainless steel, but we use them more when measuring the diameter of steel pipes. In addition, since the thin-walled stainless steel pipe may not be very flat or there are pits inside the surface due to unprocessed pits, accurate data requires measuring several points. Some measurements at the pipe mouth are inaccurate. Because the stainless steel pipe with burrs will be thicker, it is recommended to remove the burrs first and place the instrument in a flat place for measurement. Of course, it is accurate and convenient to measure with the help of tools, but the simplest and most direct way is to stamp the actual thickness on the pipe body. Stamp the specifications, model, factory year and person in charge of the pipe on the steel stamp, and stamp the actual thickness of the pipe on the thin-walled stainless steel pipe, so that users can buy and use it with confidence, honesty and trustworthiness without fraud. The above is the method for testing the thickness of thin-walled stainless steel pipes. The methods for testing the thickness of steel pipes include wall thickness measuring instruments, wall thickness micrometers, and vernier calipers. Secondly, you can visually check the labels of the steel pipes. The thickness is marked with actual thickness and label thickness, but there is a difference between the two thicknesses. It is recommended to purchase according to the actual thickness when purchasing. In this way, the actual thickness of the thin-walled stainless steel pipe can be inferred according to the actual weight. If there are special requirements for the thickness of the product required, it generally requires special customization. Post time: Apr-28-2025
