BS 1813 on specifications for dimensions of conduit dies and diestocks and guides is useful for:
Conduit dies are used to create or repair threads on the outer surfaces of pipe, conduit, or fittings so they can be mated with parts that have matching internal threads. These threading need to be accurate and well designed as any major flaws and defects could cause trouble in the interlocking of the pipes.
The dimensions provided by BS 1813 help you to produce dies that can die sizes with accurate threads for steel tubes. BS 1813 can also be used for quality control to verify that the dimensions are in accordance to ensure their sizes.
Overall, BS 1813 helps you to produce conduit dies and diestocks that can create steel conduit tubes with quality interlocking threads.
