PT testing of radiant tubes
Conversion tubes, radiant tubes, etc. are mainly produced using centrifugal casting technology, and the welding positions between tube sections require 100% PT testing to monitor the welding quality and ensure the final quality of the product. The picture shows the PT inspection of the welding position of the conversion tube, which is carried out by qualified inspectors. DTL Having complete production and testing equipment and facilities, it can meet various inspection and testing requirements.
Coloring inspection is a method of penetrant inspection. Penetrant testing is divided into three types based on the type of dye: fluorescent testing, dye penetrant testing, and fluorescent dye penetrant testing; According to the different cleaning agents, it can be divided into three types: water washing type testing, post emulsification type testing, and solvent removal type testing; According to the different types of imaging agents, they are divided into dry and wet types. There is fluorescence in the penetrant, which is too expensive and generally not needed.
