Liquid penetrant inspection is one of the oldest and most widely used non destructive testing methods. It is also called as dye penetrant inspection.Penetrant testing can be applied to most of materials including metallic and non metallic objects.This Presentation will gives you an overview about Liquid Penetrant Testing and Various methods used for Inspection
Testing comprise all the techniques of materials or products under different types of loadings. This way, the reliability of product to end user is assured and the process of material selection is done with a lot of ease.
Testing can be classified in two main categories depending upon destruction of products as
Destructive Testing
Non-Destructive Testing
These comprises all those techniques which are highly regulated on some standard in which specimen is broken/destructed.
Major destructive testing used these days are
Tensile Testing
Impact Testing
Burst Testing
Fatigue Testing
Creep Testing
Non-destructive testing (NDT) is a wide group of analysis techniques used in science and industry to evaluate the properties of a material, component or system without causing damage.
Another terms for NDT is NDE
Highly valuable technique that can save both money and time in product evaluation.
Accident prevention and to reduce costs
To improve product reliability
To determine acceptance to a given requirement
To quick information on repair criteria.
Visual Inspection
Acoustic Emission
Eddy Current
Liquid Penetrant
X-Ray/ Radiography
Magnetic method
Visual and optical inspection (or testing) is still a basic method for many applications. Visual inspection involves using an inspector's eyes to look for defects. The inspector may also use special tools such as magnifying glasses, mirrors, or bore scopes to gain access and more closely inspect the subject area. Visual examiners follow procedures that range from simple to very complex.
Detection and analysis of AE signals can supply valuable information regarding the origin and importance of a discontinuity in a material.
It has many industrial applications
Assessing structural integrity (Welding)
Detecting flaws
Testing for leaks (Pressure Vessel)
Monitoring weld quality
Research tool.
In a standard eddy current testing a circular coil carrying current is which generates eddy current then the presence of any flaws, will cause a change in eddy current and a corresponding change in the phase and amplitude of the measured current.
Applications:
Surface Breaking Cracks
SBC using Sliding Probes
Tube Inspection Conductivity
Heat Treat Verification
In it the defects/cracks are studied using a penetrant/dye. low surface tension fluid penetrates into clean and dry surface-breaking discontinuities. Penetrant may be applied to the test component by dipping, spraying, or brushing. After adequate penetration time has been allowed, the excess penetrant is removed and a developer is applied. The developer helps to draw penetrant out of the flaw so that an invisible indication becomes visible to the inspector. Inspection is performed under ultraviolet or white light
X-rays are just like any other kind of electromagnetic radiation. They can be produced in parcels of energy called photons, just like light.
These are used to produce image

Cosmetic shop management system project report.pdfKamal Acharya
Buying new cosmetic products is difficult. It can even be scary for those who have sensitive skin and are prone to skin trouble. The information needed to alleviate this problem is on the back of each product, but it's thought to interpret those ingredient lists unless you have a background in chemistry.
Instead of buying and hoping for the best, we can use data science to help us predict which products may be good fits for us. It includes various function programs to do the above mentioned tasks.
Data file handling has been effectively used in the program.
The automated cosmetic shop management system should deal with the automation of general workflow and administration process of the shop. The main processes of the system focus on customer's request where the system is able to search the most appropriate products and deliver it to the customers. It should help the employees to quickly identify the list of cosmetic product that have reached the minimum quantity and also keep a track of expired date for each cosmetic product. It should help the employees to find the rack number in which the product is placed.It is also Faster and more efficient way.
CFD Simulation of By-pass Flow in a HRSG module by R&R Consult.pptxR&R Consult
CFD analysis is incredibly effective at solving mysteries and improving the performance of complex systems!
Here's a great example: At a large natural gas-fired power plant, where they use waste heat to generate steam and energy, they were puzzled that their boiler wasn't producing as much steam as expected.
R&R and Tetra Engineering Group Inc. were asked to solve the issue with reduced steam production.
An inspection had shown that a significant amount of hot flue gas was bypassing the boiler tubes, where the heat was supposed to be transferred.
R&R Consult conducted a CFD analysis, which revealed that 6.3% of the flue gas was bypassing the boiler tubes without transferring heat. The analysis also showed that the flue gas was instead being directed along the sides of the boiler and between the modules that were supposed to capture the heat. This was the cause of the reduced performance.
Based on our results, Tetra Engineering installed covering plates to reduce the bypass flow. This improved the boiler's performance and increased electricity production.
It is always satisfying when we can help solve complex challenges like this. Do your systems also need a check-up or optimization? Give us a call!
Work done in cooperation with James Malloy and David Moelling from Tetra Engineering.
