Pipe Inspection, Testing & Marking: Pipe Inspection is a continuous process during manufacturing, it has vast importance in process & piping industry. This course has been designed to understand the basic fundamentals about various (15+) testing methods commonly used in the industry. Along with basic fundamentals, various codes & standards (ASME, ASTM, API etc) shall also be listed out and discussed in details.

This is divided into four major sections :

1. Metallurgical testing

2. Destructive Testing

3. Non-Destructive testing

4. Visual & Marking Inspections

Under Metallurgical testing (Aggressive Environment) following tests have been covered

1.Grain size (AS & SS)

2.IGC- Intergranular Corrosion Test(SS)

3.Ferrite (SS)

4.HIC- Hydrogen-induced Cracking

5.SSC- Sulfide Stress Corrosion Cracking

Under Destructive testing following tests have been covered

1.The tensile

2.Bend test

3.Flattening test

4.Impact test

5.Creep test

Under Non-Destructive testing following tests have been covered

1.Definition

2.Purpose

3.Various Types
