Provide more information, such as the source, materials, and uses.
I know φ57, and I know 3P too, but it’s the first time I’ve seen these two values multiplied together
Outer diameter Φ57, thickness 3. P valves are generally made of stainless steel; I look forward to any corrections from experts!
Φ57 denotes the diameter, and P refers to stainless steel as the material of the valve
I don’t know; I need some more detailed information
Φ57 should refer to the diameter, P denotes stainless steel as the material of the valve, and it’s unclear whether 3 refers to pressure or thickness
It’s a DN50 pipe with an outer diameter of 57 and a wall thickness of 3; in the valve markings, P denotes stainless steel
It all relates to valves now; does it seem like the information you provided isn’t complete?
Φ57: Outer diameter of the sleeve is 57. 3P: The pitch of the thread is 3.
Outer diameter 57, wall thickness 3, material is 304
