TOLERANCE OF THREADED FLANGES
ASME B16.5 provides specific tolerances for threaded flanges to ensure they fit properly, function as intended, and maintain seal integrity under operating conditions. Threaded flanges, designed to connect pipes without welding, have internal threads that match the external threads of the pipe. Here are general tolerance values for key dimensions of threaded flanges according to ASME B16.5, suitable for various sizes and pressure classes:
Diameter of Bolt Circle (P):
Tolerance: ±1.6 mm (±1/16 inch) for flanges through NPS 24, ensuring uniform distribution of bolt loads.
Diameter of Bolt Holes (Q):
Tolerance: Generally oversized relative to the bolt diameter by about +3 mm (1/8 inch), facilitating easier alignment and assembly.
Flange Thickness (T):
Tolerance: Varies but for flanges up to NPS 24, a general guideline is ±3 mm (±1/8 inch). This ensures the flange has adequate strength without unnecessary bulk.
Outside Diameter of Flange (O):
Tolerance: ±1.6 mm (±1/16 inch) for sizes up to NPS 24. This tolerance affects how the flange fits within the system and interfaces with other components.
Thread Dimensions:
The tolerance for the threaded portion of the flange is critical for ensuring a proper fit with the pipe. ASME B1.20.1 provides the standards for pipe threads, and ASME B16.5 references these for threaded flanges to ensure compatibility.
Length Through Hub (Y):
Tolerance: Specific tolerances apply to ensure that the flange aligns correctly with the mating pipe and does not interfere with thread engagement.
Inside Diameter (B):
Tolerance: For threaded flanges, the inside diameter at the base of the thread (or the end of the flange) has a tolerance to ensure that it aligns with the pipe’s outside diameter, facilitating a secure and leak-free connection. The tolerance is typically generous to accommodate the pipe threading.
Facing Finish:
Tolerance: The surface finish of the flange face, which can be critical for seal performance, especially if a gasket is used in conjunction with the threaded connection. Specific Ra values are provided based on the gasket material and type of facing.
Ensuring adherence to these tolerances is crucial for the successful implementation of threaded flanges in a piping system. The precise tolerances enable proper thread engagement, alignment, and sealing capability, which are essential for the operational reliability and safety of the system. For exact tolerance values, especially for specific flange sizes and pressure classes, a direct reference to the ASME B16.5 standard is recommended.
