英制螺纹参数（Inch thread parameter） Pipe thread data 1 and BSP are British pipe threads. However, there are BSP.Tr., BSP.PI., BSP.F. points. BSP.Tr. is a taper pipe thread for sealing joint. BSP.PI. is a parallel pipe thread, used for sealing joints, with only internal threads, and the outer threads of the BSP.Tr. are fitted. BSP.F. is a parallel pipe thread, used for general joining. Only know BSP, can not disorderly processing. Its better to make a detailed confirmation. Otherwise, oil or gas or something, the trouble is great. 2 thread G and thread BSPP The same, all British cylindrical pipe thread code, tooth type angle 55 degrees 3, how many kinds of English thread? Characteristics and representation of BSP thread? Two, BSPP (pipe thread) and BSPT (55 degrees conical pipe thread, and American 60 degrees conical pipe thread NPT relative, incompatible) 4, G thread and Rp thread contrast, which places are the same, which places are different, the two are different in use, can you use it?. Both G and Rp threads are 55 degree cylindrical pipe threads. Only countries (organizations) have different code names. G is the code name of China, France, the former Soviet Union and japan; PF is the Japanese code name; BSP and BSPP are British codes; R and K are German codes (R is internal thread, K is external thread); Ein TPY is the former Soviet Union code; Rp is the code name of ISO. 5, 1/8 and NPT1/8 thread what is the difference? Should be now GB, but NPT old standard called Z, is 60 degrees with thread sealing taper pipe thread, GB No. GB/T12716-2002M, G is 55 degrees non thread sealed cylindrical pipe thread, GB GB/T3707-2001 6 、 ask English standard pipe thread in English name is BSP? Does it have taper? The code name should be G, cylindrical pipe thread, without taper 8, Rp and G threads represent cylindrical pipe threads. Whats the difference between them? Can they be used instead of each other?. Another thing: what is the difference between Rp and Rb? They can be used in
