Johns-Manville 85% Magnesia and soot blowers, use Johns-Manville 85% Magnesia Insulation. J-M 85% Magnesia is suitable for insulating all surfaces where temperatures up to 600 deg. fahr. are encounted. Improved Asbestocel For Low-Pressure, Exhaust Steam and Feed Water Piping use Johns-Manville Improved Asbestocel Sectional Insulation, 4 ply. Sectional Improved Asbestocel is furnished in thicknesses of 2, 3 and 4 ply, each ply being approximately 34 in. in thickness. It is made in three foot sections with canvas jacket and brass-lacquered bands, to fit standard sizes of pipe: For Steam Heating Supply and Return Mains, Risers and Radiator Branches use Johns-Manville Improved Asbestocel 4 ply. Concealed radiator branches should be insulated with 3 ply Improved Asbestocel. All other low-pres sure and hot water pipes at pressures be low 25 lb. or 267 deg. fahr., except heating returns, runouts and concealed radiator branches, should be insulated with JohnsManville 4 ply Improved Asbestocel Insulation. Johns-Manville Improved Asbestocel Insulation Other Johns-Manville Insulations Johns-Manville Superex Combination Insulation is for all superheated steam piping with temperatures of 600 deg. fahr. and higher.
