Spiral pipe x ray

Spiral pipe x ray inspection in industry has a very wide range of applications.

Ray detector in accordance with the current American Society for Testing Materials (ASTM) definitions can be divided into: photographic detection, real-time imaging detection, chromatographic detection of radiation detection technology and other four categories.

Many different types of rays, which penetrate the material is easy with X-rays, γ-rays, neutron rays three. These three rays are used to non-destructive testing, where X-rays and γ-rays are widely used in boiler and pressure vessel welds and other industrial products, construction materials, defect detection, and neutron radiation is used only for special occasions. The main application is the ray detection sonar inside the macro specimen geometry defect (flaw). According to different characteristics (eg type of radiation used, the recorded material, technology and technical features, etc.) can be divided into a number of different ray detection methods. Radiography refers to X-rays or γ-rays penetrate the specimen to the film as a record of information equipment nondestructive detection method. This method is the most basic, the most widely used as a radiation detection method. X-rays with natural light and no essential difference are electromagnetic waves, but the X-ray photon energy is much larger than visible light. It can not penetrate through the object visible, and in the same time through the object and the substances of complex physical and chemical effect, can ionize the atom, so that certain substances to fluoresce, so that certain substances can produce photochemical reaction. If the workpiece is defective local area, it is an object of the ray attenuation change, causing changes in the intensity of transmitted radiation, so that the detection of the use of certain methods, such as the use of photographic film to detect the intensity of the transmission line, it can determine whether the workpiece is defective and a defect location, size.

X-ray radiography testing is the use of X-ray attenuation in the material laws and rays of certain substances can produce fluorescence, photochemical characteristics, will probe the workpiece is irradiated with rays pass through the X-ray film to make photographic film, and then after darkroom processing conditions to be reflected within the workpiece photographic film, using this film in the bright lights of the analysis, in order to determine the quality of the probe within the workpiece.

Weled steel pipe specification, Standard and identification

Welded steel pipe (steel pipe manufactured with a weld) is a tubular product made out of flat plates, known as skelp, that are formed, bent and prepared for welding.
