Product Description
ASME B16.5 Stainless Steel 304 Blind Flange DN50 Class 300 with EN 10204 3.1 MTC UT Tested

The ASME B16.5 Stainless Steel 304 Blind Flange DN50 Class 300 is a high-integrity pipeline blanking solution manufactured from UNS S30400 austenitic stainless steel. Each flange undergoes rigorous quality testing and ships with complete certification documentation for critical service applications.

Quality Certification & Testing Program
  • EN 10204 3.1 Material Test Certificate: Complete documentation including chemical composition, tensile strength, yield strength, elongation, and hardness test results validated by an independent inspection department
  • Ultrasonic Testing (UT): Volumetric inspection per ASTM A388 to detect internal discontinuities, laminations, and inclusions that could compromise pressure containment integrity
  • ISO 9001:2015 Certified Production: Manufactured under a fully certified quality management system with documented process controls from raw material receipt to final inspection
  • Hydrostatic Testing: Shell pressure test at 1.5x design pressure per ASME B16.5 to verify structural integrity and leak-tightness
  • PMI Verification: Positive material identification using XRF analysis to confirm 304 grade chemistry and eliminate material mix-up risk
Technical Specifications
Material Stainless Steel 304 (UNS S30400)
Standard ASME B16.5
Size DN50 (2 inch)
Pressure Rating Class 300
Face Type Raised Face (RF)
Blind Flange Features

Blind flanges are solid disc flanges used to blank off the end of piping systems, valves, or pressure vessel openings. Class 300 rating provides reliable sealing at pressures up to 740 psi (51 bar) at ambient temperature, making it suitable for medium to high-pressure isolation applications.

Applications

Pipeline end closure and isolation, pressure vessel manway covers, hydrotest isolation blinds, maintenance access blanking, and temporary or permanent pipeline termination in chemical processing, water treatment, oil and gas, and general industrial services.
