Q:Does the American and English fittings how to recognize it?
What's the amount of taper thread you want? This is really a bad amount. Taper pipe threads are specified: within the range of the effective thread length, there is any place that meets the requirements (as you say, NPT1/2), because the pipe threads are sealed with little depth. Only a few teeth used for sealing, but the thread specification according to the requirements, for example, you say NPT1/2-14, then the pitch is 1/14 inches, in addition, the effective thread in a certain position must be the nominal diameter of 1/2 inch. I don't know, I said so, you know, no, no, I don't have a good idea for you, but I'm sure I didn't cheat you. I'm doing this, not an expert, but it's my business, huh?.

Q:110 degree PVC pipe joint
Hello, you can use PVC two to a 45 degree elbow three back, try on the line, 35 meters of pipe according to the 1% grade to install, depends on the specific circumstances if the flow rate is larger and with construction conditions if the proposed slope is a little bigger.
