Why It Matters?

 

Flange joints are a critical component in piping systems, providing a method for connecting pipes, valves, & other equipment, and ensure a tight seal.

The ASME Piping Code B31.3 (1999 Edition) 335.1.1 9 (c)

Before
Lateral Mis-Alignment on a 56" Flange Joint Connection.
56″ Class 150 flanged joint falls out of alignment during break out.
 This code specifies the following Flange Joint Misalignment Tolerances:
 
Proper alignment of flange joints is essential to maintain the integrity of the connection and prevent leaks.
 
  • The maximum for lateral or center-line offset is 1.5 mm or less than 1/16”.
  • For rotational misalignment the Piping code specifies that it be a maximum 3 mm or less than 1/8”.
 
The above tolerances refers to pipe work being connected to pumps, rotating equipment & pressure vessels.

Understanding the importance of flange joints and alignment tools is crucial for professionals tasked with constructing, commissioning, or maintaining piping systems. Flange joints play a key role by connecting pipes, valves, pumps, and other equipment, creating a secure seal while allowing for straightforward assembly and disassembly during maintenance or repair. They help reduce accidents, leaks, and minimize time spent on tasks.


Consequently, flange alignment tools are invaluable for the precise installation and maintenance of flange joints. These tools ensure flanges are properly aligned before bolts are tightened, preserving the integrity and functionality of the connection.

Rotational misalignment is when the axis of the flanges align but the bolt holes are not. They are occasionally found when the flanges have been poorly fabricated or there are other forces acting on the flange joint such as overhang weight (relaxed state) or pipe work configuration
