Nov 13,2020 History of pipe threading and NPT and BSPT standards#0183;BSP Thread Type British Standard Pipe.This is a standard thread type that has been adopted internationally for interconnecting and sealing pipe ends.Youll find it used all throughout Europe.There are two types of BSP threads,BSPP and BSPT.BSPP refers to parallel or straight threads.Meanwhile,BSPT refers to tapered threads.Thread Standards TamesonSep 10,2020 History of pipe threading and NPT and BSPT standards#0183;National pipe threads are designated with their nominal size (3/8) followed by number of threads per inch (18) and the symbol for the thread series (NPT).Note NPS (National Pipe Straight) is not to be confused with NPS (Nominal Pipe Size) which is an American set of standards for pipes.The difference between NPT,BSPP and BSPT sealsNPT ConnectionsBSPT ConnectionsBSPP ConnectionsBSPT (British Standard Pipe Thread) is similar to NPT except there are important differences.The angle across the flanks of threads (if you sliced the fitting in half long-ways and measured the angle from root to crest to root) is 55 degrees instead of 60 degrees as it is for NPT.Another important difference is that for many BSPT pipe sizes the thread pitch is different than NPT.Thus an NPT male will sometimes fit into a BSPT fitting or vice versa but they will not seal.This is a popular fitting in China and Japan but is very rSee more on ralstoninstExplanation of common threads including BSP NPTBSPP -British Standard Pipe Parallel NPT -National Pipe Taper NPS -National Pipe Straight While the actual specified outside diameters of American National Pipe differ slightly from those of British Standard Pipe,either thread may reliably be cut onto a pipe of its respective trade size.BSPT equivalent is NPT and BSPPs equivalent is NPS.

There are two types of BSP threads -BSPT(British Standard Pipe Taper) also known as R or Rc-BSPP(British Standard Pipe Parallel) also known as G or Rp Both have similar pitch and angle 55.NPT Thread.NPT( National Pipe Taper) is the most popular thread worldwide,specially in US and Canada.Many application in oil and gas industry use NPT thread.Pipe Fittings and Port Adapters - Parker Hannifinnations,the British Standard Pipe thread form,BSP,is still used extensively to connect pipes and components in hydraulic systems.The BSP thread is offered in a straight (parallel) form known as BSPP and a tapered form known as BSPT.These threads feature a 55 History of pipe threading and NPT and BSPT standards#176; ank angle.Fittings inPeople also askWhat are the different types of NPT pipe threads?What are the different types of NPT pipe threads?NPT has a tapered male and female thread which seals with Teflon tape or jointing compound.Pipe threads used in hydraulic circuits can be divided into two types Jointing threads are pipe threads for joints made pressure tight by sealing on the threads and are taper external and parallel or taper internal threads.The sealingUnderstanding pipe threads types and designations
