Split-type SAE flange connection means that two pipes, fittings or equipment are respectively fixed on one SAE flange plate, and the two SAE flange plates are fastened together with SAE flange pads by bolts to complete the connection. Some pipe fittings and equipment have their own SAE flanges, which are also SAE flange connections.

SAE code 61 Flange Clamps FL series

Split SAE flange connection is an important connection method for pipeline construction.

 

A ——Type is connected in the form of split SAE flange, that is, a single flange (with O-ring), and the other end is the device.
B ——Type is connected in the form of split SAE flange, that is, a pair of flanges (one with O-ring).
C ——Type split type attached split SAE flange without taking over. I don’t know much about this type or how to use it. From the SN532 standard drawings, it seems that a welding head has been removed from the B-type opening SAE flange.
Type d with flange cover-connecting flange, that is, one of the pair of flanges is a blind flange (O-ring on the blind flange).
E ——Type has a connecting flange opposite to SAE flange cover, that is, a separate flange blind plate (with O- ring) and the other end of the equipment.
F-Attached split SAE flange without takeover.
