Introduction

ASME B16.5 flat flange is one of a variety of flanges, using different material classes, according to different standards of production. By welding with another flange or steel tube, flat flanges can be used for different purposes, such as closing a pipe or connecting a valve to another pipe. As the flat flange manufacturers in China, EATHU offers flat flanges of different sizes and different material grades. A flat flange has a flat surface that allows maximum contact with other parts connected to or through the flange in piping applications.
