Socket welding flange
What is socket welding flange?
Socket welding flange refers to the pipe end inserted into the flange ring ladder, welded at the pipe end and outside the flange. It comes with or without a neck. The flange with the neck pipe has good rigidity, small welding deformation and good sealing. It can be used for the occasions of 1.0~10.0MPa pressure. B flange also belongs to socket welding flange, used for sealing requirements of higher occasions. Design, It can be checked according to the whole flange.
Socket weld flange connection is an important connection mode for pipeline construction. Flange connection is the two pipes, pipe fittings or appliance materials, respectively fixed on a flange plate, between the two flanges, plus flange pad, fastening together with screws, to complete the connection. Some pipe fittings and appliances have their own flange, also belong to the flange connection.
Socket welding flanges are divided into threaded connection (wire connection) flanges and welded flanges. Low pressure small diameter wire flange, high pressure and low pressure large diameter are welded flange, different pressure flange thickness and connecting screw diameter and number are different. According to different levels of pressure, flange pads also have different materials, from low pressure asbestos pads, high pressure asbestos pads to metal pads. Flange connection is easy to use and can bear greater pressure. It is widely used in industrial pipes.
