Description
ASME B16.47 Series A & B Slip On Flange
ASME B16.47 Series A & B Slip On Flange are designed to connect pipes, valves, pumps, and other equipment to form a complete piping system. These flanges are ideal for low-pressure applications where ease of alignment and welding are crucial. Manufactured with precision, they are suitable for large-diameter piping and come in various grades to meet diverse industrial requirements.
