FOREWORD PETRONAS Technical Standards (PTS) has been developed based on the accumulated knowledge, experience and best practices of the PETRONAS group supplementing National and International standards where appropriate. The key objective of PTS is to ensure standard technical practice across the PETRONAS group. Compliance to PTS is compulsory for PETRONAS-operated facilities and Joint Ventures (JVs) where PETRONAS has more than fifty percent (50%) shareholding and/or operational control, and includes all phases of work activities. Contractors/manufacturers/suppliers who use PTS are solely responsible in ensuring the quality of work, goods and services meet the required design and engineering standards. In the case where specific requirements are not covered in the PTS, it is the responsibility of the Contractors/manufacturers/suppliers to propose other proven or internationally established standards or practices of the same level of quality and integrity as reflected in the PTS. In issuing and making the PTS available, PETRONAS is not making any warranty on the accuracy or completeness of the information contained in PTS. The Contractors/manufacturers/suppliers shall ensure accuracy and completeness of the PTS used for the intended design and engineering requirement and shall inform the Owner for any conflicting requirement with other international codes and technical standards before start of any work. PETRONAS is the sole copyright holder of PTS. No part of this document may be reproduced, stored in a retrieval system or transmitted in any form or by any means (electronic, mechanical, recording or otherwise) or be disclosed by users to any company or person whomsoever, without the prior written consent of PETRONAS. The PTS shall be used exclusively for the authorised purpose. The users shall arrange for PTS to be kept in safe custody and shall ensure its secrecy is maintained and provide satisfactory information to PETRONAS that this requirement is met.

Line Sequence Number Sequence numbers for piping line numbers shall be assigned with a three-digit number starting from 001 to 999.
4.2.5
Assigning Line Identifications Line numbers shall be assigned for process and utility lines from apparatus to apparatus. When the fluid pressure, volume or temperature changes considerably, the line number shall also be changed. As such, these changes will require a new unit number, line number or piping class. These changes should typically be demarcated at flange connections or major branches.
Parallel lines shall be numbered separately. For piping that crosses to another unit, either directly or indirectly on a pipe bridge, pipe track or other interconnecting system, the line numbers shall be assigned to the corresponding unit of origin seen in the direction of flow. For lines originating from other sources that is entering a unit without any other identification system, the line number shall be assigned corresponding to the unit they enter.
For utility headers on common pipe bridges or tracks not entering a specific unit shall be given a line number corresponding to the unit of origin seen in the direction of flow. Utility lines from utility headers entering a processing unit shall be given number(s) of the unit it is entering. 4.3
INSULATION CODES Codes for insulation shall be represented with a one to two letter code as follows: First and Second Letter Insulation tag (refer to table 4.2) Second or Third Letter Insulation thickness
