1.0 SCOPE

1.1 This Standard contains the basic information for piping material and Valve specifications. The actual specifications are contained in Piping Material and Valve Specifications Manuals, available in the "Client" Intranet system. The Piping Material and Valve Specifications are considered a part of this Standard and shall be used in conjunction with this Standard.

1.1.1 These specifications are intended to supplement the full technical requirements defined in accordance with the "Client" Standards referenced below.

1.2 Where approvals are indicated in this Standard, this refers to "Client" or its designated representative, hereinafter referred to as "Client".

1.3 Any discrepancy between this Standard and other contract or procurement documents or specification, unless specifically indicated as an exception, shall be submitted by the Contractor/Manufacturer/Supplier to "Client" for a written ruling.

1.4 All measurements are expressed in U.S. Conventional System of Measurement, followed by, in parenthesis, the equivalent SI units (metric). All SI units are for reference only and shall not be interpreted as a precise conversion.

1.5 Any proposed deviations from this Standard shall be submitted in writing to "Client" for review and approval. It is the responsibility of the individual(s) who request deviation to submit a request form in a timely manner, and in accordance with "Client" Procedure SEP 107B, Preparation of Addenda to and Deviations from "Client" Engineering Standards.
