Product Description
INTRODUCTION
Flanges are used to connect pipes with each other, to valves, to fittings, and to specialty items such as strainers and pressure vessels. The annular surface perpendicular to the axis of the pipe or pipe fitting is equidistantly distributed with bolt holes along the circumference.
Flanges are fixed (such as integrally cast flanges or welded flanges) or flexible. Flexible flanges have some rings. These rings can be used alone or in multiple assembly. Forces are applied to the socket of the pipe through these rings. Freely rotate around the axis before connecting.
Flange connection is to fix two pipes, pipe fittings or equipment on a flange plate respectively, add flange pads between the two flange plates, and fasten them together with bolts to complete the connection. Some pipe fittings and equipment have their own flanges, which are also flange connections. Flange connection is an important connection method for pipeline construction. The flange connection is easy to use and can withstand greater pressure. In the industrial pipeline, in the household, the pipeline diameter is small, and it is low pressure, and the flange connection is not visible. If it is in a boiler room or production site, flanged pipes and equipment are everywhere.
According to the connection method, the type of flange connection can be divided into: plate flat welding flange, flat welding flange with neck, butt welding flange with neck, socket welding flange, threaded flange, flange cover, butt welding ring with neck Loose flanges, flat weld ring loose flanges, ring groove face flanges and flange covers, large diameter flat flanges, large diameter high neck flanges, eight-shaped blind plates, butt weld ring loose flanges, etc.
