Standards for Piping Design and Inspection
Standards for Piping Design and Inspection: The original ASME B31 Code for Pressure Piping was first introduced in 1935 as the single document for piping design. In 1955, ASME began to separate the code into sections…

ISO Standards for Ultrasonic Testing
Ultrasonic Testing In Ultrasonic Testing we use something called “Ultrasonic Vibrations” we must know two facts about a vibration: A vibration is a back and forth movement. A vibration is energy in motion A depression of a surface from its normal position is called a displacement.

What is Acoustic emission testing?
ACOUSTIC EMISSION TESTING (AET) Acoustic Emission Test is a type of Non – Destructive Test method generally used for detecting and locating imperfections in mechanically loaded structures or components. Flaw origination and progression in a stressed component can be identified by acoustic emission test method.This…

Heat Treatment of Alloys
What is an Alloy? Since metals are insoluble in water, alcohol; they are mixed with other metals in molten state which upon cooling solidifies to a solid mixture called an Alloy. This solid state mixture is also referred as a homogeneous liquid mixture. Alloys are formed by…

Rebound Hammer Test-Non Destructive testing on Concrete
Non destructive testing for concrete Non Destructive Testing is the process of detecting the quality without destructing the material or without changing its actual properties. Rebound Hammer is also called as Schmidt hammer or Swiss Hammer or Concrete hammer test. This NDT method is used to detect…

Procedure for Liquid Penetrant examination
LIQUID PENETRANT EXAMINATION (PT) Pentrant Testing is surface defects detection method, the method can be used on any material ( i.e: Ferrous/ non-ferrous, conductive/ non conductive, metals/ non metals) But PT is limited to materials having porous surface or very rough surface. PT can be carried out…

Discontinuities in Ultrasonic Testing in NDT
This blog will discuss types of discontinuities that can be evaluated with the ultrasonic testing in NDT method. Discontinuities can be divided into three general categories inherent, processing and service Inherent discontinuities are usually formed when the metal is molten. Inherent wrought discontinuities relate to the…
