The concept of flange ratings likes clearly.A Class 300 flange can handle more pressure than a Class 150 flange,because a Class 300 flange are constructed with more metal and can withstand more pressure.However,there are a number of factors that can impact the pressure capability of a flange.Pressure Rating DesignationExample of Pressure RatingPressure-Temperature Ratings - ExampleThe Pressure Rating for flanges will be given in Classes.Class,followed by a dimensionless number,is the designation for pressure-temperature ratings as follows Class 150 300 400 600 900 1500 2500.Different names are used to indicate a Pressure Class.For example 150 Lb,150 Lbs,150# or Class 150,all are means the same.But there is only one correct indication,and that is Pressure Class,according to ASME B16.5 the pressure rating is a dimensionless number.See more on wermacExplore furtherFlange Ratings and Flange Classes for ASME FlangeshardhatengineerPressure - Temperature Ratings (psig) Class - 150#appliedmcFLANGE TABLES Temperature/Pressure Ratings for Steel Flangesisis-fluid.ukFlange Pressure Rating Explained (and Charts blog.projectmaterialsPressure Rating ANSI Class vs PN - ValviasvalviasRecommended to you based on what's popular FeedbackFlanges General - Pressure-Temperature Ratings ASTM and Flanges General - Pressure-temperature Ratings ASTM and ASME - Free download as PDF File (.pdf),Text File (.txt) or read online for free.flange rating
