What do you mean by the term thread size Please explain What does 0.125 Inch stand for in 0.125 Inch NPT thread?

One thread per .125 inch or 8 threads per inch. One thread per .125 inch or 8 threads per inch.

Do you use metric pipe fittings?

no, none exist, you have NPT, (National pipe thread) which are tapered and you have BSP which is straight. they have a different thread pitch as well. however you can run into some that are called OSB, (o-ring sealed back), they are usually 9/16-NF, 3/4-NF of 1 1/8-14. NF is National fine.

No. Even if Kenya has plans concerning nuclear technology it is totally against nuclear weapons. In fact, obeys th NPT and it's pursuing the idea of the total elimination of nuclear weapons

What do you measure to determine the size of a tap?

In American standard sizes (SAE), the cut threads for bolts (cut by a die) and their corresponding internal threads (cut by a tap) are designated by 1) the furthermost outside diameter (i.e. across the peaks of the thread ridges) of the bolt, and 2) the number of thread ridges per inch (TPI). Generally, each diameter in the SAE sizes has two standard TPI variations: for example, a 3/8" bolts may have either 16 TPI (National Coarse, or NC) or 24 TPI (National Fine, or NF). The later size of tap would be designated "3/8"-24." For water taps/spigots for attachment to iron pipe, the size is determined by the National Pipe Thread (NPT) size of the tap's integral male or female threads for affixing to the supply line. Generally, this is designated by the nominal size of the inside diameter of the supply pipe, in inches. For water taps/spigots to be attached to copper tubing, the size is determined by the nominal size (diameter) of the copper tubing supply line to which it is intended to be attached.

What is the difference between BSPT and NPT?

Thread angle is different (55° vs 60°).NPT threads are flattened at the peaks and valleys, while BSPT threads are rounded.Threads per inch (TPI) is different for two (except for a couple of cases).

What is full form of NPT?

Full form of NPT is "National Pipe Thread"

What is the difference between SAE and NPT?

NPT is a standard for threaded pipe and fittings. NPT stands for national pipe thread. NPT fittings are tapered thread fitting and usually rely on mechanical deformation in between the male and female fittings to create a seal in addition with teflon tape. Over tighteting may result in a leakage SAE O-ring fittings are straight fittings and rely on the O-ring to create the seal rather than deformation as in NPT fittings. Since these fittings do not depend on deformation chances of a broken fitting are virtually eliminated.

What is a PTF thread?

A PTF thread is the same as a NPT thread except that it has one thread less at the small diameter end. It is used when there are space (depth) considerations.

What a npt valve is in a water tank pressure system?

npt, national pipe thread, is a standard for threads on a screw. I (not a plumber) don't believe "npt valve" makes sense , but probably refers to a valve which has npt threading. Yes, a NPT Valve would be a valve with pipe threads as opposed to a sweat valve which has solder connections. There are several other type of piping connections too.
