NACE Stress Relief: Clarifying Fibre Deformation Requirements in NACE MR0175/MR0103 Standards

Introduction

This article provides a simple question-and-answer format related to NACE MR0175/MR0103 standards. The question is about the reference in NACE MR0175 part 2 Annex A section A.2.1.2 to fibre deformation greater than 5%. The question seeks clarification on whether it is referring to surface strain when a residual tension stress is applied as a result of manufacturing processes. The answer is a simple “”YES,”” providing the necessary clarification.

Understanding Fibre Deformation Requirements in NACE MR0175/MR0103 Standards

NACE MR0175/MR0103 standards are critical for ensuring the safe and reliable operation of equipment in harsh environments. One of the requirements in these standards is related to fibre deformation, which is defined as the change in the shape of a material due to the application of stress.

According to NACE MR0175 part 2 Annex A section A.2.1.2, fibre deformation greater than 5% is not allowed in certain materials. However, there is some confusion about whether this requirement applies to surface strain when a residual tension stress is applied as a result of manufacturing processes.

Clarifying the Requirements

The answer to the question is a simple “”YES.”” The fibre deformation requirement in NACE MR0175/MR0103 standards applies to all forms of deformation, including surface strain caused by residual tension stress. Therefore, it is essential to take this requirement into account when designing and manufacturing equipment that will be used in harsh environments.
