What does mean by ANSI class 300 Flange?
A flange is designated with different pressure classes, showcasing their load-bearing capacity. A class 300 flange is a low-pressure class flange whose weight holding capacity reduces as the temperature in the system increases. These flanges can be constructed with stainless steel, carbon steel, aluminum, ductile steel, etc. The 300 flanges can efficiently connect different piping equipment to create a versatile pipeline.

ANSI B16.5 Class 300 Blind flanges vs ANSI B16.5 class 300 Lap Joint Flanges

• ANSI B16.5 Class 300 blind flange is designed without a bore and is used primarily as blanks. These blinds help in terminating the flow of media in the system. ANSI B16.5 class 300 Lap Joint Flanges is designed with a two-component assembly consisting of a stub end and a ring-type sealing.
• The pressure holding capacity of lap joint flanges is lower than blind flanges.
• Blind flanges are in constant contact with pressurized fluid. Lap joint flanges are not in continuous contact with fluids, thereby making the grade resistant to corrosive affluents.
• Lap joint flanges have space to swivel around and line up to opposite bolt holes. Blind flanges don’t have such movement capability.

ANSI B16.47 Series A Class 300 Flanges vs ANSI B16.5 Class 300 Flanges

• The ANSI B16.47 Series A Class 300 flanges are available in sizes between 24 to 60 inches. ANSI B16.5 Class 300 flanges cover sizes up to 24 inches.
• The ANSI B16.47 is generally heavier and stronger than the ANSI B16.5 class flange.
