Answer
# 1
BSW (British Standard Whitworth)
A coarse thread devised and standardised at Manchester in 1841
by British Engineer Sir Joseph Whitworth (1803 - 87). It is
used in many types of engineering throughout the world,
although in Britain its use is now being superseded by the
ISO metric system.
Angle of Thread = 55 Degrees
Sizes range from 1/16" to 2-1/2"
BSP = British Standard Pipe, or BSPP = British Standard
Parallel Pipe, or BSPF = British Standard Parallel Fixed.
This thread needs a gasket or seal to be gas/liquid tight.
Angle of thread = 55o degrees
NPT - National Pipe Thread Taper
Characteristics of NPT (also known as ANSI/ASME B1.20.1 Pipe
Threads, General Purpose):
tapered thread 1o 47'
truncation of roots and crests are flat
60o thread angle
pitch is measured in threads per inch
Parallel ('straight') threads, BSPP (British Standard Pipe
Parallel Thread), which have a constant diameter; denoted by
the letter G.
Taper threads, BSPT (British Standard Pipe Taper Thread),
whose diameter increases or decreases along the length of
the thread; denoted by the letter R.
