The Jargon, calculations, and charts defining BSP threads differ greatly from standard metric and inch threads. This webpage will explain the difference between the various series, how each parameter is defined, and show how to find the correct basic dimensions and tolerances for each thread.

Fastener and Screw / Bolt Design, Formula and Calculations. External Pipe Threads per. ISO 228-1, Pipe threads where pressure-tight joints are not made by the threads. These pipe threads are also known as Whitworth pipe threads. Where: D = Major Dia.internal thread. D 1 = Minor Dia.internal thread. D 2 = Pitch diameter internal thread.
“Pipe thread ISO 228 G ¼ LH” specifies left-handed parallel threads with a size designation of 1/4; Applications. BSP threads are commonly used worldwide in water supply, cooling, pneumatics, and hydraulic systems. BSPP threads, specifically, are used on hose ends, adapters, ports, and other high-pressure applications.
5 lis 2021 · Many people think that BSP Thread size is the dimension of the outer diameter of the male threads, however this is not the case. To determine the thread size you will need to subtract ¼” (0.25”) from the outer measurement to specify the correct fitting. You can easily do this using the chart below. Thread Type.
British Standard Pipe Thread (BSPT) The threaded part (s) of plumbing fittings are usually made to a British Standard Pipe Thread size (BSP). BSP sizes don't match up with what you measure on the scale of a ruler, which can obviously cause some confusion.
The BSP thread is a type of pipe thread whose coils take the shape of a letter 'V' with an angle of 55 degrees. In addition, they have rounded ridges. BSP threads are also referred to as British or Whitworth threads (named after the inventor of this standard)
