Reducing Raised Face Long Weld Neck Stainless Steel Flanges
1. Stainless steel flanges connection is to fix two pipes, pipe fittings or equipment on a stainless steel flanges, and between the two stainless steel flanges, with flange pads, bolted together to complete the connection.
2. Some fittings and equipment have their own stainless steel flanges and are also flanged. stainless steel flanges connection is an important connection method for pipeline construction.
3. The stainless steel flanges connection is easy to use and can withstand large pressures.Stainless steel flanges connections are widely used in industrial piping.
4. Stainless steel flanges is to make the pipe and pipe connected parts, connected to the end of the pipe. There are holes on the stainless steel flanges, and bolts make the two stainless steel flanges tightly connected.
