Hebei Xinyue provide a series of British standard of flanges in carbon steel and stainless steel, include types of plate、blind、welding neck、slip on、 threaded etc.
101 Plate Flange
Plate Flange is the most common flange, it 's wihtout a low or high hub. The pipe is welded onto inside of the bore of the flange.
105 Blind Flange
Blind Flange is a flange without a bore. This flange is used for easy access to lines in which one side of rear part of piping system is closed or reopened after closure and to interior of pipe.
111 Wedleing Neck Flange
Welding Neck Flange is generally referred to as a "high hub" flange. It is designed to transfer pressure to the pipe and reduce high pressure at the base of the flange. Welding Neck Flange is a butt-welding flange with the best design among currently available flanges because of its unique structure.
112 Slip-on Flange
Slip On Flange has a low hub as the pipe is inserted onto the bore of the flange before welding. The pipe is welded into inside and outside of the bore of the flange in order to guarantee sufficient strength and prevent leakage. The bore of all slip on flanges is slightly larger than outer diameter of the pipe connected.
113 Threaded Flange
Threaded Flange is similar to slip-on flange. However, it has a screw thread of female screw on the bore of the flange. The most important advantages are that the threaded flange can be bonded without welding and used in highly explosive areas with danger or low-pressure process and welding at toom temperature.
