1. Scope

1.1 This practice provides tables of dimensions of preformed insulation that may be used in fabricating 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 Prefabrication and Field Fabrication of Thermal Insulation Fitting Covers for NPS Piping, Vessel Lagging, and Dished Head Segments. The tables provide dimensions for use in forming pipe fitting covers for NPS pipe operating at high temperature and low temperature and NPS pipe heat traced with tubing up to 5/8 in. (16 mm) in outside diameter. The tables also include dimensions for use in forming thermal insulation into curved segments, lagging, and dished heads for application on vessels. This practice does not apply to reflective-type insulation.

1.2 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use.

1.3 The values stated in inch-pound units are to be regarded as the standard. The values given in parentheses are provided for information purposes only.

2. Referenced Documents (purchase separately) The documents listed below are referenced within the subject standard but are not provided as part of the standard.
