Sealing Conditions of weld neck flanges

Weld neck flanges connections need to be used with bolts, such as forged weld neck flanges with holes on it, bolts can be used to make the weld neck flanges tight, because gaskets are placed between the sealing surfaces of two weld neck flanges, after tightening the nut, the specific pressure on the surface of gaskets reaches a certain value, then deforms, and fills the bumps on the sealing surface to make the connection. Keep tight and tightly sealed.

　　Meanwhile, the ANSI B16.5 Stainless Steel CL600 RF Weld Neck Flange connection is a kind of detachable connection. Container weld neck flanges and stainless steel weld neck flanges can be divided according to the components connected. According to the structure type, there are integral weld neck flanges, looper weld neck flanges and thread flange. Weld neck flanges and butt welding flange are common integral flanges. Weld neck flanges has poor rigidity, which is suitable for pressure P < 4 MPa occasion;weld neck flanges is also called high neck flange, which has high rigidity and is suitable for high pressure and temperature occasions.

　　In addition, weld neck flanges is a flange connected with equipment or pipeline through fillet weld. Weld neck flanges is also called lap welding flange. Weld neck flanges is connected with pipeline by inserting the pipe into the inner hole of the weld neck flanges to the appropriate position, and then overlapping welding. Weld neck flanges is suitable for pipeline system with low pressure level and low pressure fluctuation, vibration and vibration. Weld neck flanges is widely used because of its easy alignment and low cost in welding and assembling.
