Several years back API listed a NPT thread called long line pipe - basically the start of taper is smaller and the diameter at the hand tight plane is the same. The L1 dimension is longer than a standard NPT.

Does anyone have the old copy of API - I'm guessing it was published in the 1970's.

Does anyone know the offset for the 2 inch size?
