i
Class for pipe fittings is a standard defined by the ASME/ASTM. Though stated with a # sign, such as 150# or 3000#, it is not a direct pressure rating.  The pressure rating is dependent on material and temperature and is found by consulting an appropriate reference guide.
i
Threaded couplings go on threaded pipe. Socket Weld couplings go on plain end pipe.
