BSPPfittings can be measured more simply, and their specifications can be identified with a few basic calculations. To determine the thread size: Measure the thread's outer diameter (OD) in inches. Subtract 25% from the OD measurement. So if the OD of a BSPP male thread measures one inch (1"), the thread size will be 3/4. AnM6 thread has a basic major diameter of 6 mm. Typically, metric thread callouts also come with the thread pitch, such that an M6 × 1 threaded bolt has a basic major diameter of 6 mm and a thread pitch of 1 mm. When purchasing a threaded fastener, make sure you have both the diameter and the thread pitch. Doyou know threaded pipe coupling dimensions? Choose the quality steel coupling manufacturer Hebei Sanvo in China and find the threaded pipe coupling dimensions chart for knowing more information. Notes: 1/8''-1''Taper Tapped(NPT), 1 1/4''-2'' Sraight Tapped(NPS), 2.5''-6'' Taper Tapped(NPT). Merchant Couplings in 2'' are available Taper Jointingthreads – are pipe threads where pressure-tight joints are made on the threads. The mating of the male and female threads forms the seal. They always use a taper male thread, but can have either parallel or taper female threads. The sealing effect is improved by using a jointing compound. Specifications NPT is defined by ANSI / ASME standard B1.20.1.
