Development of a Manufacturing Method to Produce Elbow Part

本文对石油和天然气工业用管状弯头零件的热成形进行了实验研究。该零件成形的主要挑战是克服截面形状和壁薄的制造限制，并在后续热处理后满足零件的其他硬度和冲击强度要求。这个初始项目的目标是开发一种基于规模实验的制造方法来形成这个新部件。目前，弯头零件的成形对Iafrate Machine Works （IMW）来说仍然是一个挑战，各种试验已经交付了不符合尺寸规格且高度可变的零件。由于这些原因，需要一个受控的实验室分析和实验，以提供一个有效的和可重复的过程来制造弯头。

The research deals with experimental studies in hot forming of a tubular elbow part utilized in the oil and gas industry. The primary challenge in the forming of this part is in overcoming manufacturing limitations of cross-sectional shape and wall thinning and to meet other hardness and impact strength requirements for the part after subsequent heat treatment. The objective of this initial project is to develop a manufacturing methodology for forming this new part based on a scale experiment. Currently forming of the elbow part has remained challenging for Iafrate Machine Works (IMW) and various trials have delivered parts that did not meet dimensional specifications and were highly variable. For these reasons a controlled laboratory analysis and experiment is required to deliver an efficient and reproducible process to manufacture the elbow.
