Comprehensive Guide to Seamless, Welded, & HCW Pipes (Grades 304, 316, 321) for Piping Engineers, Inspectors & Buyers.
“This course contains the use of artificial intelligence.”
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..

Requirements

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.
