1. Socket Bore Diameter:
This is the diameter of the inner hole where the pipe is inserted into the socket. It must be measured accurately to ensure that the pipe can be inserted smoothly and leave the necessary expansion gap. ASME B16.11 has strict regulations on the inner diameter of the socket for different pipe diameters and pressure levels.
2. Socket Depth:
Measure the depth of the pipe inserted into the socket. This depth determines the length of the weld and the stability of the connection.
3. Overall Length of the Coupling:
Measure the overall length of the pipe coupling to ensure that it meets standard or custom requirements.
4. Wall Thickness:
Measure the wall thickness of each part of the pipe coupling, especially the wall thickness of the socket, to ensure that it meets the minimum wall thickness requirements for the design pressure level.
5. Thread Profile and Pitch:
Ensure that it meets the standard (such as ASME B1.20.1 NPT tapered pipe threads).
6. Effective Thread Length:
Measure the effective length of the thread to ensure sufficient engagement depth for sealing and connection strength.
