BSPP and BSPT stand for British Steel Pipe Parallel and British Steel Pipe Taper respectively and the terms typically refer to the types of screw thread that is used to seal pipes together by interlocking the external and internal threads. Clearly there is a differentiation to be made in terms of the sizes since one has to fit inside the other. The BSPT diameter decreases with the length of the thread, but the BSPP stays the same.

Typically these types of pipe can be combined into different types of joints. The first is jointing threads where a solid connection is made through the force of pressure between the two threads. The male always uses a taper male thread, but the female can either be parallel or tapered. The longscrew threads are parallel pipe threads that use the compression of a material in between the two threads to achieve pressure sealed tightness.
