DUPLEX STEEL ASME SA182 F53 SO SLIP ON FLANGE 承插焊法兰
DUPLEX STEEL ASME SA182 F53 SO SLIP ON FLANGE 承插焊法兰
Slip on flanges, like plate flat welding flanges, are flanges that extend steel pipes, pipe fittings, etc. into the flange and are connected to equipment or pipelines through fillet welds. They are also flat welding flanges because they have a short neck. Thereby increasing the strength of the flange and improving the bearing strength of the flange. So it can be used in higher pressure pipelines. Disadvantages: The cost of the SO flange is higher than the plate flat welding flange, and it is easier to bump during transportation due to the characteristics of its shape.
The Slip ON Flanges surface can be Raised Face(RF), Flat Face(FF), Ring Joint Face(RTJ), and some other faces.
We GUTE is the manufacturer that provide all kinds of steel flanges like Slip on Flanges, Plate flat Flanges, Weld Neck Flanges, Blind Flanges, Socket Weld Flanges, and so on, and also other special flanges according to the client's requirement.
