INTRODUCTION
This document describes the Pipe class specification which has been used in the project EPC for
construction of oil loading pier no.3 in Kenar for the storage and loading of TORC products,
Turkmenistan.
The following system establishes procedures used for identifying pipes. The system is based on
Process Industry Practices (PIP) to provide a uniform standard consistent with industry practices and
client requirements.
1.1 Pipe Class Designator System
The base piping class designator system consists of four alpha-numeric fields containing one or
two characters each. Each field describes various features of the piping line class. Exceptions,
modification, or additions may be made to the this specification, by adding a numeric character
after the fourth field to indicate the changes made
First field1.1.1
The first field defines the pressure rating and consists of two numeric characters.
