The DPT TEST ON PEB MEMBERS are discuss in this post. The Pre Engineered Building (PEB) System is growing rapidly in almost all parts of the world. These are the steel buildings in which excess steel avoids. This complete building system is Pre Engineered. And to make the easy production. And easy assembly on the site.
The use of PEB is highly economical and Eco friendly. By the application of this we can save the natural resources. It has numerous advantages.
Dye Penetration Testing (DPT) is a test uses to identify the discontinuities in welding joints in PEB members. And uses to detect the cracks, fractures, pinholes, porosity, potholes, in PEB members.
DPT TEST ON PEB MEMBERS
Dye Penetration Testing has different names such as,
- Liquid Penetrate Inspection
- Penetration Testing
It is a simple test. And easy test to identify the discontinuities in welding joints. And to detect the cracks, fractures, pinholes, porosity, potholes, in PEB members. Using this method all the surface defects and flaws are easily identify and rectify. This test carries out without difficulties. This is one of the oldest test for identification of the cracks, fractures, pinholes, porosity, potholes, in PEB members.
The specimen to test (PEB Member) cleans for applying of the Dye. It must be free from dirt, dust, paint, oil, grease and other foreign materials.
After this the penetrant applies to the surface of the PEB Member. And it allows to remains for three to five minutes on the member. This makes to get the penetrant sink into the cracks,pores,etc. This depends on the size of the PEB members to test.
The excess penetrant removes from the surface and a white developer applies to the penetrant.
Now defects like, the cracks, fractures, pinholes, porosity, potholes identifies. It is clearly visible on to the surface of PEB Member.
The defects like, the cracks, fractures, pinholes, porosity, potholes identifies and rectifies.
