Fracture Failure Analysis of Welded Steel Pipes
Date:2025-03-26
Fracture failure in welded pipes is caused by material defects, welding flaws, or excessive stress.
-
Brittle Fracture: Occurs in low-temperature conditions or due to improper heat treatment.
-
Fatigue Fracture: Cyclic loading leads to crack initiation and propagation, common in pipelines.
-
Stress Corrosion Cracking (SCC): Environmental factors accelerate crack formation, especially in oil and gas pipelines.
-
Prevention Methods: Advanced welding techniques, stress-relief treatments, and non-destructive testing (NDT) improve durability.
Failure analysis helps in designing more robust welded pipe systems and preventing catastrophic failures.
