I. Introduction

The Outer Diameter (OD) of a flange refers to the measurement of the distance across the outer edge of the flange, typically in a circular shape. It is a crucial parameter in flange design and installation, as it determines the compatibility and functionality of the flanges.

The importance of Outer Diameter lies in its impact on the proper fit and alignment of flanges. Flanges connect or join various piping components, such as pipes, valves, and fittings, in a secure and leak-proof manner. To ensure a tight and effective connection, the flanges must have a matching Outer Diameter.

Flanges with incorrect OD measurements can lead to numerous issues. If the OD is too small, it may result in gaps or misalignment between the flanges, leading to leakage or loss of pressure. On the other hand, an oversized OD can cause difficulties in proper installation or alignment, hindering the overall efficiency and integrity of the system.

Proper and accurate OD measurement is crucial not only for the correct assembly and functioning of flanges but also for maintaining the overall safety and reliability of the piping system. It ensures a secure seal, prevents leakage, minimizes the risk of accidents or equipment failures, and promotes the effective flow of fluids or gases.
