Integral flanges are also called long welded neck flanges (LWN flanges). The working pressure ranges from class150 to class2500, and the materials are usually carbon steel and stainless steel. Long weld neck flanges are very suitable for high-pressure pipelines because the weld is far away from the ring to avoid the combination of bending stress and weld stress. Long weld neck flanges perform well under certain stress and temperature fluctuations. According to customer needs, long weld neck flanges are available in various lengths, inner diameters, outer diameters and sizes. Many factories produce long-necked flanges by welding steel pipes in the neck of the flange, so the long-necked flanges produced are of poor quality (prone to safety accidents), but they are cheap.

The opening and closing parts of the gate valve are the valve gate, the movement direction of the gate is perpendicular to the direction of the fluid, the gate valve can only be fully opened or fully closed, it can not be used for regulation and throttling.
