What does B16.25 specify?

• A. Weld end preparation
• B. Gasket selection
• C. Flange bolt torque
• D. Surface finish requirements

Answer: (A)

B16.25 focuses on the ends prepared for butt-weld connections. It defines the welded ends used on piping components so mating parts can be joined with proper fusion and strength. The crucial part is the end preparation geometry—how the edge is shaped, the bevel form, and the related tolerances—because this directly controls weld quality and the ability to achieve full penetration during welding. Gasket selection, bolt torque, and surface finish requirements are governed by other standards or sections and are not specified by this standard. In practice, following B16.25 ensures compatible butt-weld ends on flanges and fittings, enabling consistent fabrication and safe, leak-tight joints when welded.
