Analysis of Overheating Combustion Temperature in Stress Relief Furnace Machine

Abstract

Abstract— The oil and gas industry faces challenges in controlling the heat treatment process of pipe joints using stress relief furnaces to maintain material quality and durability after production. This process aims to eliminate residual stresses and enhance the pipe's structure after forging (swaging). However, there is a problem regarding excessive temperature control. Excessive temperatures can cause material damage, such as cracking or decreased mechanical performance, which affects the quality of the final product. The purpose of this study is to analyze and identify the primary causes of quality issues in the heat treatment process using a systematic approach, and to provide recommendations for process improvements that reduce the risk of material failure. This study employs the Root Cause Analysis (RCA) method, using a Fishbone diagram, to identify the root cause of the problem, and Failure Mode and Effects Analysis (FMEA) to assess potential failures related to overheating. The results indicate that poorly controlled firing temperatures are the primary cause of material failure, and the FMEA analysis reveals several critical points in the process that pose high risk. Based on these findings, recommendations are made to enhance temperature control, refine operating procedures, and improve operator training to minimize the risk of damage and improve overall product quality.
