What is the testing of penetrations of liquid?

Liquid penetration testing is a process used to test and check various objects for defects or deficiencies. It is a non -destructive type of test process, which means that the object is not damaged or destroyed as tested. Many production and industrial equipment relies on testing of liquid penetration to confirm the safety and quality of its products.

During the testing of the liquid, the dye is applied to the surface of the building. Through the process known as the "capillary action", the dye quickly penetrates any shortcomings or cracks in the exterior of the building. After a predetermined period of time, the object is cleared clean and all surface dye is removed. A developing powder is used to help brighten or detect any remaining dye that has settled on surface cracks or cavities. The remaining dye indicates the location of any shortcomings or defects that must be repaired on the object. The first uses a visible colorful colorVO to indicate shortcomings, while the other relies on fluorescent dye, which is invisible to the mere eye. When using a fluorescent dye, the inspectors must explore the object under the ultraviolet (UV) light to look at the defects.

Liquid penetration penetration can be used on metal and non -metal objects, including ceramics, plastic and even glass. It is usually used in production plants, to test things such as cars, aerial equipment, machines and consumer items. Non -destructive testing of liquid penetration is also an excellent method of inspection of building components without damage or destroying the object during the process.

This test process helps to detect defects such as cracks, holes or cavities that may not be detected by visual or other control procedures. Testing the surface of the liquid can also detect welding deficiencies in the seam between twoa variety of items. Finally, this test can be used to detect corrosion or other chemical processes that could endanger the structural integrity of the object.

The

testing of the liquid penentant is known for its relatively low costs, especially compared to other material testing techniques. The process is easy to feasible and the results are available quickly. Even inspectors who are relatively new in this test process can easily interpret the results of this test in most cases.

While this test offers many advantages to users, it also has a number of limitations to be considered. Testing of the penetration of liquid is designed only to find deficiencies on the surface of the object and do not detect problems deep below the surface. In addition, the surface of the building must be relatively smooth and without dirt, grease and other substances that can distort the test results.
