Flange Types and Their Applications – Weld Neck, Slip-On, Blind, Socket Weld, Threaded, Lap Joint
Flanges may look simple, but each type has a specific role in how a piping system handles pressure, temperature, and vibration. Using the wrong flange type can lead to leaks, misalignment, or even catastrophic failure.This guide explains the most common flange types used in process, chemical, and power plants — what they’re for, where to use them, and what to avoid.1.
