Custom Stainless Steel Flange
Ming Xiao Mfg have a freind factory which specialize in Stainless Steel Flange & Rings manufacturing,the Flanges and Rings are made from hot forging, then CNC turning & machining.
Flanges are disc-shaped parts that are most common in pipeline engineering. The flanges are used in pairs and with the matching flanges on the valve. In plumbing, flanges are primarily used for pipe connections. In the pipelines that need to be connected, a variety of flanges are installed. The low-pressure pipelines can use wire-bonded flanges, and the welding flanges are used at pressures above 4 kg. A gasket is placed between the two flanges and then bolted. Different pressure flanges have different thicknesses and use different bolts.
Pumps and valves, when connected to the pipeline, the parts of these equipment are also made into the corresponding flange shape, also known as flange connection. Connection parts that are closed at the same time by bolting on both planes are generally referred to as “flanges”. For example, the connection of ventilation ducts may be referred to as “flange parts”. However, this connection is only a part of the equipment, such as the connection between the flange and the water pump, it is not good to call the pump “flange parts”. Smaller such as valves, etc., can be called “flange parts”.
