What you'll learn

  • Distinguish Manufacturing Types: Clearly differentiate between Seamless (SML), Welded (WLD), and Heavily Cold Worked (HCW) pipe manufacturing processes.
  • Analyze Material Chemistry: Understand the specific roles of Molybdenum in Grade 316 and Titanium in Grade 321 (Stabilized Grades).
  • Interpret Heat Treatment Rules: Navigate Table 2 to determine mandatory annealing temperatures and quenching requirements for various grades.
  • Master Inspection Protocols: Learn the requirements for Hydrostatic vs. Nondestructive Electric (NDE) testing and Weld Decay tests.
  • Verify Compliance: perform visual inspections, check dimensional tolerances (Wall Thickness), and validate mandatory pipe markings.
  • Apply Knowledge: Test your understanding with real-world scenarios and a comprehensive Capstone Quiz.

Description

“This course contains the use of artificial intelligence.”

Are you a Piping Engineer, QA/QC Inspector, or Procurement Specialist working with Stainless Steel?

Understanding ASTM A312 is mandatory for anyone dealing with austenitic stainless steel piping in high-temperature or corrosive environments. It is one of the most widely used specifications in the Oil & Gas, Petrochemical, and Power Generation industries.

However, reading through raw code standards can be dry, confusing, and time-consuming.

This course turns the standard into a clear, visual, and practical learning experience.

We have broken down the ASTM A 312/A 312M – 09 PDF into a structured 6-part video series that covers every critical aspect of the specification without the fluff.

What is covered in this course?

  • Module 1: Scope & Manufacture: Seamless vs. Welded vs. Heavily Cold Worked (HCW) and the 35% reduction rule.

  • Module 2: Heat Treatment: Deep dive into Annealing, Quenching, and Grain Size rules (focusing on H Grades).

  • Module 3: Chemistry & Strength: detailed breakdown of Tables 1 & 4. Why is Molybdenum added to 316? Why is Titanium added to 321?

  • Module 4: Testing & Inspection: Hydrostatic testing, Eddy Current (NDE), Flattening tests, and Weld Decay.

  • Module 5: Workmanship & Markings: Dimensional tolerances, repair limitations, and supplementary requirements (S1-S9).

  • Module 6: Capstone Quiz: A final "Knowledge Check" with 5 detailed Q&A scenarios to validate your learning.

Why take this course?
Whether you are preparing for an API 570 certification, approving vendor drawings, or inspecting pipe at a mill, this course gives you the technical confidence to ensure compliance.
