1.1 This practice provides tables of dimensions of preformed pipe insulation that shall be used in fabricating insulation covers for use on valves, ells, tees, flanges, and vessels in the pressure range from 150 to 1500 psi (1 to 10 MPa). These tables, which are part of this standard, are published separately as the ASTM Recommended Dimensional Standards for Fabrication of Thermal Insulation Fitting Covers for NPS Piping and Vessel Lagging. In addition, the ADJC0450A tables for Short Radius (SR) and Long Radius (LR) Elbows Insulation Fitting Covers for piping are included in this practice. The tables were developed to provide dimensions for shop fabrication use in forming pipe insulation fitting covers on NPS pipe operating at high temperature and low temperature. The tables also include dimensions for use in forming thermal insulation into curved segments, and lagging, for application on vessels. This practice does not apply to reflective-type insulation, insulation on screwed elbow
