PURPOSE AND USE OF PROCESS INDUSTRY PRACTICES
In an effort to minimize the cost of process industry facilities, this Practice has
been prepared from the technical requirements in the existing standards of major
industrial users, contractors, or standards organizations. By harmonizing these technical
requirements into a single set of Practices, administrative, application, and engineering
costs to both the purchaser and the manufacturer should be reduced. While this Practice
is expected to incorporate the majority of requirements of most users, individual
applications may involve requirements that will be appended to and take precedence
over this Practice. Determinations concerning fitness for purpose and particular matters
or application of the Practice to particular project or engineering situations should not
be made solely on information contained in these materials. The use of trade names
from time to time should not be viewed as an expression of preference but rather
recognized as normal usage in the trade. Other brands having the same specifications
are equally correct and may be substituted for those named. All Practices or guidelines
are intended to be consistent with applicable laws and regulations including OSHA
requirements. To the extent these Practices or guidelines should conflict with OSHA or
other applicable laws or regulations, such laws or regulations must be followed.
Consult an appropriate professional before applying or acting on any material
contained in or suggested by the Practice.
This Practice is subject to revision at any time.

12.2.4.1 A blank insulation material data sheet, PIP INSR1000-D3, should be
used to specify insulation material system requirements for a specific
project.
12.2.4.2 The material system data sheets should be used to specify the
following for a specific project:
a. Service Description - The service description, including service
temperature range and applicable insulation thickness table. If two
or more material data sheets are required for a project, this
information can be used to separate the requirements between data
sheets.
b. Approved Manufacturers - The approved insulation material
manufacturer(s) and brand name(s).
c. Accessories - Accessory materials associated with the insulation
material system and if appropriate, the approved accessory
manufacturer(s) and product brand name(s).
12.2.4.3 The material system data sheets provide default values for material
descriptions based on common industry practice. However, these
values may be changed in accordance with specific project
requirements. Components and corresponding descriptions may be
added as appropriate for specific designs.
12.2.5 Insulation Thickness Table
12.2.5.1 Insulation thicknesses should be calculated for a specific project by
insulation service and material type. A blank Insulation Thickness
Table, PIP INSR1000-F, should be used to record calculated
thicknesses.
12.2.5.2 PIP INEG1000 provides additional information regarding design basis
and calculation methods for determining insulation thicknesses.

12.2.5.3 PIP INSR1000-F provides default values for insulation thicknesses
based on design parameters in PIP INSR1000 Table 1 for personnel
protection, using maximum thermal conductivity for glass fiber felt
insulation in accordance with ASTM C1086.
12.2.5.4 The default thicknesses may be changed in accordance with other
design parameters, insulation materials or insulation design basis (HC,
PP or combination), as appropriate for specific designs.
12.2.5.5 Two or more insulation thickness tables may be required for removable
covers for a specific project.
12.2.5.6 Purchaser-format insulation thickness tables may also be used if
appropriate.
12.2.5.7 Insulation thickness tables, including purchaser-format required for a
project should be indicated on Documentation Requirements Sheet,
PIP INSR1000-D1.
