Score: 4.8/5 (18 votes) . BSP is the abbreviation for British Standard Pipe.The thread, as defined by the ISO 228 standard, uses Whitworth standard threads, and is among a number of technical standards for screw threads that has been adopted internationally for interconnecting and sealing pipes and fittings.

BSP Thread Type - British Standard Pipe You'll find it used all throughout Europe. There are two types of BSP threads, BSPP and BSPT. Find the caliper measurement in the chart and cross reference the nominal NPT pipe size. Don't get confused, the actual measurement is not the same as the NPT pipe size. Is SAE and UNF the same?

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.

The following quotation from the obituary from The Times of 24 January 1887 to Sir Joseph Whitworth (1803–1887) shows. The British Standard Fine (BSF) standard has the same thread angle as the BSW but has a finer thread pitch and smaller thread depth. This is more like the modern "mechanical" screw and was used for fine machinery and steel bolts.

The British standard pipe thread (BSP thread) is a family of standard A list of 15 thread sizes are defined by the standards, ranging from 1/16 to 6.

NPTF, BSPT and BSPP measure 1/4" larger than their actual size. For example, a 1/4" NPTF, BSPT or BSPP will actually measure 1/2" on the O. D. of the threads. JIC, SAE O-ring & Flat Face threads measure as listed below. The first number listed is the size of thread, the second number is the threads per inch. Adapter Sizing Chart Thread

You can cross-reference the bore size on the following chart with thread pitch and threads per inch to find your desired size and its related specs. BSPT-tech.

NPT fittings will have threads with a 60 degree spread while BSP threads will have a 55 degree spread. A manual thread pitch gauge. Use this chart to easily compare NPT and BSP. How to Measure Threads Whether you're working with NPT or BSP fittings, you'll typically be able to tell the difference between tapered and straight connections.

04/10/  · The second kind of BSP thread is the taper thread. The British Standard Pipe Taper thread (BSPT) has a changing diameter. It may increase or decrease along the length of the thread. Some taper threads have the letter R on them as an identifier. It's common to incorrectly identify tapered pipes as NPT pipes. However, NPT pipes have a 60° flank
