INSULATES WITH SUPEREX-85% MAGNESIA TO LOWER POWER PRODUCTION COSTS When Pacific Gas and Electric Com pany invested S80,000,000 in its new 771,000-horsepower electric generating giant at Moss Landing, California...the insulation, like all other materials, had to meet rigid specifications. For ibis im portant project,Jahns-ManvilleSuperex85% Magnesia double-layer insulation was used, on superheated steam pipes. Superex Combination Insulation con sists of Superex*, a J-M insulation for temperatures to 1900F, and J-M 85% Magnesia. It was installed at the Moss Landing plant for maximum thermal efficiency and long trouble-free service. This double-layer construction, proved in over a quarter-century of outstanding on-the-job performance, utilizes the higher heat resistance of Superex next to the hot surface--the greater insula tion value of J-M 85% Magnesia for the outer layer. It eliminates through joints, protects the jacket against scorching and is unharmed by expansion encountered in pipes carrying superheated steam. J-M 85 sulation for temperatures to 60OF. It will not distort regardless of its length of service. It fits snug, stays tight. Heat savings, therefore, remain constant for the life of the equipment on which it is applied. Whatever the insulation--it must be properly engineered and installed to pay maximum dividends. That's why Johns-Manville offers industry the serv ices of experienced J-M Insulation Engi neers and J-M Insulation Contractors. These men stand ready to combine their talents and give you an insulation job that will more than pay off your initial investment with maximum fuel savings.
