But the 200 P. heat would ^eventually cause the cork to shrink \and crumble. It b never used for gtoperetures over 150 F. The second suggestion, 3" of Magnesia and 6" of cork, would ^provide sufficient insulation to por trait economical operation of the / line. However, three inches of mag' oetia .is more than is required to ^`reduce temperatures to within /` practical limits for the outer layer ; of cork when the line is operating *; at 200 F. Atso, it would not take Kfull advantage of the higher insuJ lating efficiency of cork. The third suggestion, Standard Thick Magnesia and 7" of cork lagging, is the most practical and economical specification for this line. Standard Thick Magnesia is sufficient to bring the temperature at the cork below 150 F. Over the Magnesia, 7" of cork lagging will provide adequate insulation to maintain the 75 below zero tem perature for the length of time re quired on this job. And the cork logging can. be tightly sealed to prevent damaging vapor pene tration when the line is operating at low temperatures. An unusual problem like this cannot, of course, be solved by any simple rule of thumb. Dozens of factors must be analyzed and pro vided for. Armstrong's engineers are qualified by training and ex perience to give you the right an swer. That's why it pays you to talk over your insulation problems with an Armstrong engineer. He can furnish expert advice, at well os the right mftteriab and skilled workmen for applying them. MttCI INSULATION CMtCX LIST Th\\ chart.
