An elastic ring is arranged between the flange plate and the welding boss. The two top surfaces of the elastic ring are respectively bonded to the flange plate and the welding boss. There are also a plurality of screw holes on the flange plate. The center of the flange is symmetrically distributed in the center, and the flange is made of a composite sheet, which is a polyethylene plastic layer, a rubber layer and a PVC layer in turn.

The flange plate with neck flat welding flange is made of composite plate. The plate has a three-layer structure, and the middle is an elastic rubber layer.
