ASME B16.5 Forged Flanges Standard & Engineered Models
Browse TSV's complete portfolio of weld neck, blind, and slip-on high-integrity forged piping flanges engineered for severe pressure and temperature manifolds.
ASME B16.5 Weld Neck Flange (WNRF / WN-RTJ) Heavy Forged Series
Full penetration tapered hub weld neck flange transferring stress directly into pipe wall, delivering superior fatigue endurance under cyclic thermal stress.
High-Pressure Heavy Forged Blind Flange (BLRF / BL-RTJ)
Solid forged disc flange designed to terminate pipeline sections and vessel nozzles under maximum hydrostatic pressure with zero deflection.
Spectacle Blind, Spacer & Paddle Blind High-Integrity Assembly
Figure-8 spectacle blind and paddle blanks providing unmistakable visual verification of positive mechanical isolation during maintenance.
Forged Grain Flow Alignment & Flange Sealing Integrity
Engineered with directional closed-die hot forging to produce continuous metallurgical grain flow along flange hub contours.
Continuous Closed-Die Grain Flow
Hot forging preserves unbroken metallic fiber lines conforming to the flange neck radius, yielding 35% higher tensile impact resistance than cut plate blanks.
Precision Serrated Gasket Facing
Precision CNC lathe grooving generates standardized spiral or concentric serrated phonographic finish (125-250 µin Ra) for leak-proof gasket seating.
100% Volumetric Ultrasonic Examination
Every forged billet and finished flange undergoes 100% ultrasonic testing per ASTM A388 to ensure total freedom from internal laminations and porosity.
