ASME B16.5 Class 300 2NPS RF Sch10S LJ

Application Scenarios:

Lined pipes (plastic/PTFE): Stainless Steel flange + corrosion-resistant stub end

Frequent disassembly points (bunker ports, bypass lines): Rotatable for bolt alignment

Steam lines: Compensate thermal expansion to prevent flange stress cracks

Retrofit projects: Replace only stub end to add corrosion layer, reuse old flange

Large-diameter temp connections (drainage): Quick install without welding


Key Features:

Two-piece design: Flange rotates 360° for easy bolt alignment

Cost-efficient: Alloy stub end + carbon steel flange (save 50% cost)

Zero-weld maintenance: Replace stub end without touching pipe welds

Thermal stress relief: No direct weld to pipe → lower crack risk

Pressure handling: Seal by stub end, flange only supplies bolt load

Custom Solution: Share media/temp/pressure – we optimize stub end material!
