Black iron fittings are typically rated for a pressure of 150 psi (pounds per square inch) for most applications. However, the actual pressure rating can vary based on the size and specific type of fitting, as well as the temperature of the fluid being transported. It's essential to consult the manufacturer's specifications for precise ratings and to ensure safe usage in specific conditions.
What medium and temperature as there is something called "pressure temperature relationship"
BIP is Black Iron Pipe.
Pipe ratings are the operating pressures that a pipe can be constantly operated at. There are a few classes of plumbing pressures. Schedule 40 black iron is 150 psi class, meaning that the "operating pressures" are 150 psi. The 300 psi class is the class for most schedule 80 black iron (no seam [welded]). Each class has it's own fittings at the same ratings. The fittings wont be listed as a schedule just a class or a psi rating. Other ratings can exceed 3000 psi for hydraulic actuated machinery applications. Again, these classes have there own set of 3000 class fittings which are usually forged instead of cast. The ratings include a safety factor of 2 and an extra surge allowance of 100 psi for very short term operation. The rating only goes to the yield strength of the pipe not the failure strength, know the difference. So the burst pressures someone else gave as the pressure rating (2700 +psi) is wrong unless the person asking this question was trying to make a "pipe bomb."

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.
Not sure what you mean by pressure fittings. Threaded fittings for steel pipe are pressure fittings. Steel pipe with a 3/4" O.D. is known as 1/2" I.P.S. (Iron Pipe Size) pipe.

Yes, A105 fittings can be welded to black iron pipe, as both materials are compatible for welding. A105 is a carbon steel specification commonly used for forged fittings, while black iron pipe is also made from carbon steel. However, proper procedures, including appropriate welding techniques and filler materials, should be followed to ensure a strong and reliable joint. It's important to consider the application and any potential standards or regulations that may apply.
