What should a procurement agent collect before requesting a heating element quote?

A procurement agent should collect the heating element material, element shape, diameter, hot zone length, cold end length, overall length, resistance, voltage, power, furnace temperature, atmosphere, quantity, drawings and replacement photos.

If any item is unknown, mark it as unknown instead of guessing. The technical review can then focus on the missing data and avoid quoting a heating element that does not fit the furnace.
