Stainless steel guardrails, as a type of pipeline for transporting media, must be used whether in accordance with national or ministerial standardsXOnly after undergoing flaw detection and passing the inspection can the steel pipes be released from the factory. So, how many long steel pipes are within the scope of flaw detection?
The general length of spiral steel pipes is12This length is within the range of flaw detection. The range of flaw detection for spiral steel pipes is determined by the flaw detection equipment. Generally, the minimum value of flaw detection equipment is7.5Metre, with a maximum length of12Rice, if it is not a fixed length12How to conduct flaw detection in the case of a meter? We can use the division method to lower than7.5The production of spiral steel pipes that require flaw detection is determined by their multiples or by their combination being greater than7.5The spiral steel pipe of the meter is used for flaw detection.
XRadiographic testing takes advantage of the different thicknesses of materialsXThe difference in the degree of ray absorption is achieved through the use ofXThe radiographic radiography method and real-time imaging of industrial television reveal the internal defects of materials, components and welds from films and images. Such as cracks, shrinkage cavities, gas holes, slag inclusions, incomplete fusion, incomplete penetration, etc., determine their positions and sizes. The quality of materials or products is evaluated by observing the nature, size and location of their defects, thereby preventing major accidents caused by internal defects and poor processing of the materials.XRadiographic testing is utilizedXRays can penetrate substances and have the property of attenuation within substances, which is a non-destructive testing method for detecting defects.XThe wavelength of rays is very short, generally0.001～0.1nm.XRays travel in a straight line at the speed of light and are not affected by electric or magnetic fields. They can penetrate matter and undergo attenuation during the penetration process, which can sensitizing films.
