It has NPT threads for creating a tighter seal than straight threads and bolt holes for connecting to flat surfaces. This flange is made of malleable iron, which has high tensile strength, and has a black finish that resists rust in oil and gas applications. This class 150 fitting meets standards ASTM A-197, ASME B 1.20.1, and ASME B 16.3 for quality assurance. Class is a standard relating to tolerance, construction, dimension, and wall thickness, but it is not a direct measurement of maximum working pressure.Pipe fittings are components used for connecting, terminating, controlling flow, and changing the direction of piping in many different industries.
