The information you are requesting is available from pipe and fitting manufacturers and reference standards. Do a little searching on the internet.

Here's another hint: What code or standard governs Class 3000 fittings? What code or standard governs pipe Schedules? Does fitting Class correlate to pipe Schedule or the other way around? Is a threaded nipple a fitting or a pipe?

I through lbs are mean for thickness???

just a small thread nipple. 1 1/4 NPT male to 1 1/4 NPT.

But we specification lbs. I do not know how many lbs i need. in order to get the Internal diameter i want...

Depending on the length, you should buy roughly 2 lbs of pipe.

Schedule 160 ASTM A106 seamless threaded nipple = 1.160 inch ID.

I have a chart with a forged hex nipple and it shows 27.9mm (1.098"). You're talking about a straight seamless pipe nipple though, right?
