As per API 6A temperature classification, -20 deg F to 250 deg F operating temperature range.
The maximum temperature in Class F insulation is 150* C.
schedule is the thickness of the pipe and class is pressure/temperature rating of a fitting or pipe
Class Y insulation can withstand a max temperature of 90 degrees centigrade. Examples are Cotton, Silk, Paper, Wood, Cellulose, etc.
black patent is the really shiny one, whereas the black pu is the dull, unshiny looking one
They're usually spec'd for 55 or 65 degrees C average temperature rise (so 55 or 65 C above ambient temp), but the hot spot can get significantly hotter, and is limited by the insulation class of the transformer. Class B is 130C, class S is 240C, so there's a big difference between insulation. Temperature is dependent upon loading of the transformer, and what cooling systems are engaged.
why shouldn't you act pu in school or class

Fission of U-235 or Pu-239 is not very sensitive to temperature, but neutrons are absorbed better if they are slowed down after production, this is the function of the moderator.
The Pu Pu Chinese resteraunt is at 2060 Centre St, in West Roxbury, MA. Then there is the PU PU Hot Pot in Cambridge, England.

The maximum temperature in Class F insulation is 150* C.
Class F insulation is the class of insulation which will give a service life of 20000 hours when maintained continuously at a temperature of 155 degee, which is the temperature index of class F.
Class O
polyurethane (PU)
pu
The Thai translation for "boy" is "หนุ่ม" and for "girl" it is "สาว".
pu-nit (pu, not poo)
