Specializing in the production of handrail floor flange manufacturers


There are three types of flange sealing surface of the handrail floor flange: the parts that connect the pipe to the pipe are connected to the pipe end. There are holes on the flanges, and bolts make the two flanges tightly connected. The flanges are sealed with gaskets. Flanged pipe fittings refer to pipe fittings with flanges (lugs or sockets). It can be made by casting (not shown in the picture), or it can be formed by screw connection or welding. The flange connection (flange, joint) is composed of a pair of flanges, a gasket and several bolts and nuts.

The flange is divided into threaded connection (wire connection) flange, welding flange and clamping flange. There are wire flanges and ferrule flanges for low-pressure small diameters. Welded flanges are used for high-pressure and low-pressure large diameters. The thickness of flanges and the diameter and number of connecting bolts are different for different pressures.
