The maximum working pressure for an ANSI Class 900 flange varies depending on the temperature of the fluid being transported. At a standard temperature of 100°F (38°C), the maximum working pressure is typically around 1,480 psi (pounds per square inch). However, this value decreases at higher temperatures, so it's essential to consult a pressure-temperature rating chart for precise figures. Always ensure compliance with relevant codes and standards for specific applications.

What does ANSI Flange ratings mean?
ANSI flange ratings refer to the pressure-temperature ratings established by the American National Standards Institute (ANSI) for flanged connections in piping systems. These ratings, typically designated as Class 150, Class 300, Class 600, etc., indicate the maximum pressure that a flange can safely handle at a given temperature. The ratings help ensure that flanges are compatible with the materials and operating conditions of a system, promoting safety and reliability in fluid transport.
What is the dimension difference between ANSI 300 Flange and PN16 Flange?
PN 20 is equal to ANSI 150 & ANSI 300 equals PN 50.
How many bolts for ANSI 600 flanges?
The number of bolts required for ANSI 600 flanges depends on the flange size and the specific design. Generally, ANSI flanges have a standard number of bolt holes that can range from 4 to 12, depending on the diameter. For example, a 6-inch ANSI 600 flange typically has 8 bolts, while larger sizes may have more. Always refer to the relevant flange standards or manufacturer specifications for precise details.
Is PN16 the same as ANSI 150?
PN16 and ANSI 150 are not the same, although they are often used in similar applications. PN16 refers to a pressure rating in bar for European standards, indicating a maximum pressure of 16 bar at a specified temperature. In contrast, ANSI 150 is an American standard that denotes a pressure rating of 150 psi at ambient temperature. The two standards are based on different measurement systems and may have variations in flange dimensions and pressure capabilities.
Pressure rating of a ANSI 1500?
The ANSI 1500 pressure rating, designated by the American National Standards Institute (ANSI), typically refers to a flange or valve that can withstand a maximum pressure of 1500 psi (pounds per square inch) at a specified temperature. However, the actual pressure rating can vary based on the material and design of the component, as well as temperature effects. It's important to consult specific standards and manufacturer specifications for accurate ratings and applications.
What is ansi 150?
Ansi 150 is a pressure grade of flange ie. Ansi #150 Flange. For steel flanges this is specified by ANSI B16.5.
What is the dimension difference between ANSI 300 Flange and PN16 Flange?
PN 20 is equal to ANSI 150 & ANSI 300 equals PN 50.
Is pn16 flange rating is equal to ansi 300 flange rating?
It's #150.
Why is it called ansi 150 ansi 300 etc?
The number (e.g. 150) is the lb force the flange is rated to.
What is the pressure rating of ANSI 125?
The pressure rating of ANSI 125, also known as Class 125, typically corresponds to a maximum working pressure of 125 psi at a temperature of 100°F. This classification is part of the ANSI/ASME B16.1 standard for cast iron flanges and fittings. It's important to note that the actual pressure rating can vary with temperature, so consult the relevant standards for specific applications.

Generally, ANSI flanges have a standard number of bolt holes that can range from 4 to 12, depending on the diameter. For example, a 6-inch ANSI 600 flange typically has 8 bolts, while larger sizes may have more. Always refer to the relevant flange standards or manufacturer specifications for precise details.

What is difference between ANSI b 16.5 class 150 and ANSI b 16.5 class 1500?
The Class ranges of ANSI Standards refers to the pressure and temperature limits of usage for the Product. The class ranges from 150 and goes upto 2500. They denote the different pressure ranges. For example, A 316 Stainless Steel valve in class 150 can be used only upto 275psi Same 316 Stainless Steel valve in class 1500 can be used only upto 3600psi Does that clears your doubt?
What is a flange rating?
*Any flange having different MOC bears the rating with respect to international standards like ANSI B16.5.*It is a designed pressure that a flange can withstand.*For example a flange is having the following specification:25NBX150#,FORGED CARBON STEEL as per ANSI B16.5is having 150 psi flange rating.It can withstand 150 psig pressure safely.(Noting that in most cases the pressure-temperature charts of a given spec will allow for normal operating pressure to far exceed the class rating at ambient temperature. For example a 150# flange in A105 Carbon Steel will rate for 285PSI at -20 to 100 Degree F. For more information see www.texasflange.com The original intent was to class the parts to safely hold the given pressure at relatively high temperature. Since often times the operating temperatures are much lower the flanges can usually be used well above their given rate. When in doubt take your design criteria to a company that deals in it and ask for the specifics.)*Pipe flanges that are made to standards called out by ASME/ANSI B16.5 or ASME/ANSI B16.47 are typically made from forged materials and have machined surfaces. They are typically in "Pressure Classes" such as 150#, 300#, 600#, 900# 1500#; however, ASME B16.47 still recognizes the 75# or "Class 75" flange for certain low pressure and low temperature applications. These "Pressure Classes" have both pressure and temperature ratings for specific materials. The flange faces are made to standardized dimensions and are typically "flat face" "raised face" "tongue and grove" or "ring joint" styles, although other obscure styles may be permitted. Flange designs are available as "welding neck" "slip-on" "lap joint" "socket weld" "threaded" and also "blind flange". The gasket type and bolt type are generally specified by the standard(s); however, sometimes the standards refer to the ASME Boiler and Pressure Vessel Code (B&PVC) for details ( see ASME Code Section VIII Division 1 - Appendix 2 ). These flanges are recognized by ASME Pipe Codes such as ASME B31.1 Power Piping, and ASME B31.3 Process Piping. Materials for flanges are usually under ASME designation: SA-105 , SA-266 or SA-182.*Please visit following link and download the software, you will get both pressure v/s temperature rating of flange:
