Hebei Xinyue provide a series of Germany standards of flanges in carbon steel and stainless steel, include types os plate、blind、welding neck、lapped joint、threaded、hubbed slip on etc.
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.
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.
Weld 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.
Screwed 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.
