Simplified Thicknesses for Pipe Insulation
Johns-Manville molded pipe insulation*--85% Mag nesia, Superez, and Thermobestos--are manufactured in accordance with Simplified Thicknesses. The pur. pose of Simplified Thicknesses is to permit the use of double-layer construction in all pipe sizes and thick nesses since the outside diameter of the pipe insulation is approximately the same as that of standard steel pipe.
The table below gives the approximate wall thickness of pipe insulation for each nominal thickness. It also gives the corresponding pipe size of the outer layer for double-layer construction. In specifying, ordering or otherwise referring to these materials, only nominal thicknesses should be used. Approximate wall thick nesses are given only for use in determining heat trans mission or for other engineering calculations. The 1" nominal thickness is available in pipe sizes up to and including 6". For pipe sizes of 7*' and larger, the mini mum thickness furnished is nominal IV2". For pipe sizes and thicknesses available, refer to the data sheets on 85% Magnesia, Superex and Thermobestos.
At temperatures above 600 F, pipe expansion is a significant factor. For this reason, pipe insulation
should be applied in double-layer construction with staggered joints for all temperatures above 600 F. This construction prevents excessive heat lasses and surface temperatures at the joints, opened by pipe expansion, thus eliminating scorched or burned jackets. The construction also eliminates the potential fire hazard of exposing jackets to higher temperatures at the joints.
