ASME B16.1 flanges are pipe connection components made mainly from cast iron, following the ASME B16.1 standard. This standard sets the rules for flanges and flanged fittings used in low-pressure piping systems. For flanges
in Classes 25, 125, and 250, it covers dimensions, pressure ratings, tolerances, marking, and testing. ASME B16.1 flanges are often made from ASTM A126 Class B cast iron, which is strong enough for many non-critical
applications. Tesco Steel & Engineering, a reliable ASME B16.1 flanges manufacturer, supplies these products with consistent quality and durable performance, making them ideal for plumbing and utility systems.
Each ASME B16.1 flange has a few key parts that make it work. These include the face, bolt holes, hub and bore. The most common types are slip-on flanges, blind flanges and threaded flanges. Slip-on flanges slide over the
pipe and get welded for a secure fit. By blocking off a pipe, blind flanges make it simple to inspect or repair the system later. Threaded flanges screw onto the pipe, so there’s no welding needed. These flange types
are chosen based on how much pressure the system handles and how the pipe is installed.
ASME B16.1 flanges are designed for systems that run under low pressure and temperature. They are widely used in water lines, plumbing systems, fire protection, and HVAC setups. In plumbing, they help connect pipes and
fittings in homes and buildings. For fire systems they work well in sprinkler setups and other safety tools. These flanges are also used in industrial setups like food and beverage units where conditions are mild. ASME
B16.1 Class 125 is one of the most used pressure classes for such applications. The material, pressure rating and face type make them a solid pick for everyday utility piping.
