Blind Pipe Flanges|Factory direct sales Stainless Steel flange

A blind pipe flange is used to seal the end of a piping system or pressure vessel openings to prevent the escape of contents. Blind pipe flanges also allow for easy access to the interior of a line or vessel once it has been sealed. Blind pipe flanges are manufactured in various materials including carbon steel, stainless steel, aluminum.


Blind pipe flanges are essential to the proper function of many industrial piping systems. A pipe flange is a disc or plate that is attached to the end of a pipe in order to provide stability and support. Blind pipe flanges are used when it is necessary to block off the end of a piping system. They are also used when it is necessary to connect two dissimilar pipes together. Blind pipe flanges are available in a variety of materials, including carbon steel, stainless steel, and aluminum. In addition, they are available in a variety of sizes and Pressure Ratings. When selecting a blind pipe flange, it is important to consider the intended application and the operating conditions of the piping system.
