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 deviation in the wall thickness of steel pipes, so we cannot completely rely on the thickness on the label when applying it. We should measure the actual thickness according to actual needs. Then, let's take you to understand the wall thickness detection method of thin-walled stainless steel pipes.

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 measured object and reaches the material interface, the pulse is reflected to the probe to determine the thickness of the measured material by accurately measuring the time it takes for the ultrasonic wave to propagate in the material.

2. The wall thickness micrometer is a measuring instrument for measuring the wall thickness of thin-walled stainless steel pipes, which uses the principle of spiral pair to read the distance between the spherical measuring surface and the flat measuring surface on the arc scale frame. The micrometer is generally more accurate when measuring the thickness of raw materials. We will 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 stainless steel thin-walled steel pipes may not be very flat or there are pits inside the surface due to unprocessed treatment, accurate data requires measuring several points. Some measurements at the mouth of the steel pipe are inaccurate. Since the stainless steel pipe with burrs will be thicker, it is recommended to remove the burrs first and place the instrument on a flat surface 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 steel pipe body. Put the specifications, model, factory year, and person in charge of the steel pipe on the steel stamp, and stamp the actual thickness of the steel pipe on the thin-walled stainless steel pipe, so that users can rest assured when buying and using it, and be honest and trustworthy without fraud.

The above is the method for detecting the thickness of thin-walled stainless steel pipes. The methods for detecting the thickness of steel pipes include wall thickness measuring instruments, wall thickness micrometers, and vernier calipers. Secondly, you can look at the label of the steel pipe. The thickness is marked with the actual thickness and the label thickness, but there is a difference between the two thicknesses. It is recommended to purchase according to the actual thickness. In this way, the actual thickness of the thin-walled stainless steel pipe can be inferred from the actual weight. If there are special requirements for the thickness of the product required, special customization is generally required.
