(Clause 8.1)
All dimensions in millimetres.
Figure description:
- Type: Technical engineering diagram of a pipe assembly.
- Key Components:
- Taper Pipe: Labeled on the left side at the transition point.
- Threads: Labeled on the right end of the pipe.
- Dimension A: Indicates the longitudinal length from the inner shoulder of the left coupling to the right end of the threaded section.
- Features: Half-sectional view showing wall thickness and internal structure.
- Units: All dimensions are in millimetres (mm.
