Grooved flange is generally used when connecting grooved pipe fittings. The grooved pipe fittings that play a sealing function mainly consists of three parts: sealing rubber ring, clamp and locking bolts. The rubber seal ring located in the inner layer is placed on the outside of the connected pipe, and coincides with the previously rolled groove, then clamped on the outer buckle of the rubber ring, and then fastened with two bolts. Due to the characteristic sealable structure design of the rubber sealing ring and clamp, The grooved flange has good sealing, and as the fluid pressure in the pipe increases, its sealing is correspondingly enhanced.

The grooved flange is used for the conversion of the grooved pipe connection to the flange connection. It is a special connection fitting used when the groove connection is connected to the flange.
