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

•Ultrasonic testing

•Magnetic Penetrant testing

•Radiographic testing

•Liquid Penetration testing

•Acoustic emission testing

Under Visual & Marking inspection following tests have been covered

1.Hydro test

2.Visual Inspection

3.Marking

Students or professional will be able to learn the basics & fundamentals of inspection and testing requirements in the piping industry. The fundamentals covered in this course are not only useful for the the professionals working at site but also for the entry level team members who want to build the fundamentals and refresh the basics. once enrolled there will be lifetime access to the course material.
