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.
PN 20 is equal to ANSI 150 & ANSI 300 equals PN 50.
Nominal Pressure for Class 150 refers to the pressure rating of piping and fittings used in various applications, typically measured in pounds per square inch (psi). For Class 150, the nominal pressure is generally around 150 psi at a temperature of 100°F (38°C). However, the actual pressure rating can vary based on the material and temperature of the system. It's important to consult relevant standards or specifications for precise applications.

Class 150 (AKA 150#) refers to the pressure/temperature rating of the valve. That class applies to steel and alloy steel valves. Common classes are 150, 300, 600, 900, 1500, 2500, 4500. There are also interpolated ratings and special classes, which basically are intermediate ratings. For more information click the Related Link shown below.
Ansi 150 is a pressure grade of flange ie. Ansi #150 Flange. For steel flanges this is specified by ANSI B16.5.

It's #150.
The number (e.g. 150) is the lb force the flange is rated to.
*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:
Class 150 is a pressure class rating for flanges and fittings that indicates the maximum pressure at which they can safely operate. Carbon steel is a type of steel alloy primarily composed of carbon and iron, known for its high strength and durability. When a component is specified as class 150 carbon steel, it means that it is designed to withstand pressures at class 150 while being made of carbon steel material.
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?
Flanges are specified by, for example, “weld neck RTJ” or “socket weld RF”. Dimensions of the ASME B16 ring connection surface and his RTJ seal. 5. Nominal Pipe Size (NPS). This is a dimensionless designation used to define the nominal pipe size (NPS) of a connecting pipe, fitting, or nozzle. Examples of this are NPS 4 and NPS 6. Flange pressure class. This refers to the pressure and temperature rating of the flange and is required for all flanges. Examples include Classes 150, 300, 600, 900, 1500, and 2500.

No. The answer is same as class 150
ASME B16.5 refers to a standard that covers pipe flanges and flanged fittings for sizes ranging from ½ inch to 24 inches in nominal pipe size. The "class" designation indicates the pressure-temperature ratings of the flanges, with common classes being 150, 300, 600, 900, 1500, and 2500. Each class corresponds to specific pressure limits at designated temperatures, ensuring that flanges can safely handle the operating conditions of the piping system.
