Common Performance Issues in Seamless Steel Tubes During Use:
Corrosion: Susceptibility to rust and chemical degradation, especially in harsh environments (e.g., acidic/alkaline conditions or high humidity), leading to wall thinning or failure.
Cracking: May occur due to stress corrosion, fatigue, or manufacturing defects, particularly in high-pressure or cyclic-loading applications.
Deformation/Mechanical Damage: Bending, buckling, or ovality under excessive load or improper handling, compromising structural integrity.
Wall Thinning: Erosion or abrasion from fluid flow (e.g., in pipelines) or mechanical wear, reducing pressure-bearing capacity.
Pitting/Scaling: Localized surface damage from oxidation or impurities, potentially initiating cracks or leaks.
Thermal Fatigue: Cracking or warping under repeated thermal cycling (e.g., in heat exchangers).
Hydrogen Embrittlement: Loss of ductility due to hydrogen absorption in high-strength steels, causing sudden brittle fractures.
Dimensional Inaccuracy: Deviations in thickness or diameter (from poor manufacturing) affecting fit or performance.
Key Mitigations: Material selection (e.g., corrosion-resistant alloys), protective coatings, proper installation, regular inspections, and adherence to operational limits.
