Our main projects including stainless steel flanges, duplex steel flanges, super duplex steel flange, pipe fitting manufacturing and sales. We have produced 316 stainless steel threaded flanges for many years, looking forward to reaching a long-term cooperative relationship with you.
316 Stainless Steel Threaded Flanges,Also called flange disc or flanges. 316 Stainless Steel Threaded Flanges is a part connected between the shaft and the shaft, used for the connection between the end of the pipe; It is also useful for flanges at the inlet and outlet of equipment, for the connection between two devices, such as reducer flanges. 316 Stainless Steel Threaded Flanges connection or flange joint refers to a detachable connection made of flange, gasket and bolt which are connected to each other as a group of combined sealing structure.
Pipe flanges refer to the flanges used in pipe fittings and the import and export flanges used in equipment. There are holes in the flange, and the bolts make the two flanges tight together. The flanges are gasketed. Flanges consist of threaded connection (wire connection) flanges, welding flanges and clamping flanges. Flanges are used in pairs. Wire flanges can be used for low pressure pipes and welded flanges for pressure of more than 4 kg. Put a gasket between the two flanges and tighten them with bolts.
Flanges of different pressures have different thicknesses, and they use different bolts. Water pumps and valves, when connected with pipes, the local parts of these equipment are also made of corresponding flange shape, also known as flange connection. All in the two plane around the use of bolt connection at the same time closed connection parts, are generally called "flange", such as the connection of ventilation pipe, this kind of parts can be called "flange class parts". But this connection is only a part of the equipment, such as the connection of the flange and the water pump, it is not good to call the water pump "flange parts". Relatively small, such as valves, can be called "flange parts".

316 Stainless Steel Threaded Flanges advantage is that there is no need to weld, flange deformation on the cylinder or pipe generated additional torque is small. The disadvantage is that the flange thickness is large and the cost is high. Suitable for high pressure pipeline connection.
Threaded flange is the inner hole of the flange is processed into pipe thread, and with the threaded pipe matching connection, is a non-welded flange. Compared with welding flanges or butt flanges, threaded flanges are easy to install and maintain, and can be used in some pipelines where welding is not allowed on site. Alloy steel flanges have sufficient strength, but not easy to weld, or welding performance is not good, you can also choose threaded flanges.
