What you'll learn

Distinguish Applications: Confidently select between ASTM A671 (Low Temperature) and A672 (Moderate Temperature) based on service conditions.
Decode Designations: Master the alphanumeric "Grade" and "Class" system (e.g., CC70 Class 22) to specify materials correctly.
Understand Heat Treatment: Learn the metallurgy behind Stress Relieving, Normalizing, and Quenching protocols required by the standards.
Navigate Quality Control: Comprehend the specific requirements for Radiography, Transverse Tension Tests, and Weld Bend Tests.
Manage Manufacturing: Understand the EFW welding process, plate selection, and permissible repair procedures for high-pressure pipe.

No specific code book is required (we will cover the essential tables and clauses), but having access to the standards is helpful.

Description

Are you a Piping Engineer, Quality Inspector, or Procurement Specialist struggling to navigate the complex specifications of Electric-Fusion-Welded (EFW) pipe?

“This course contains the use of artificial intelligence.”

Pipe ordered to the wrong specification or heat treatment class can lead to catastrophic failures in high-pressure lines. This course is designed to demystify ASTM A671 and ASTM A672, the two industry-standard specifications for EFW steel pipe used in atmospheric, lower, and moderate temperature services.

Through a structured 7-module curriculum, we break down the dense technical language of the code into clear, actionable knowledge.

Course Curriculum:

Module 1: The Fundamentals: We start by defining the scope. You will learn exactly when to apply A671 vs. A672.
Module 2: Cracking the Code: We decode the confusion between "Grades" (Material) and "Classes" (Processing).
Module 3: Manufacturing: A look at Pressure Vessel Quality plates, welding processes, and reinforcement rules.
Module 4: Heat Treatment: The core of the standard. We explain Stress Relief, Normalizing, and Quenching requirements.
Module 5: Inspection & Testing: Detailed walkthroughs of Radiography (RT), Hydrotests, and Mechanical testing.
Module 6: Repairs & Supplements: How to handle defects and when to order Supplementary Requirements (like Charpy Impacts).
Module 7: Scenario Quiz: Test your knowledge with real-world engineering scenarios.
