SAES-L-100 – Applicable Codes and Standards for Pressure Piping Systems

This standard provides guidelines for the design, construction, and inspection of piping systems owned or operated by Saudi Aramco, using applicable Codes such as ASME B31.1, B31.3, B31.4, and B31.8. It also serves as a basis for selecting Saudi Aramco Engineering Standards and Materials System Specifications that complement the applicable Codes.

Moreover, this standard outlines additional design requirements for piping systems, which are in addition to the requirements set out in the Codes. It ensures that the piping systems are designed, constructed, and inspected to meet Saudi Aramco’s safety, reliability, and quality standards.

Applicable ASME Codes

This passage outlines the various piping systems owned or operated by Saudi Aramco and the applicable codes for their design, construction, and inspection. The codes listed are ASME B31.1, B31.3, B31.4, and B31.8, and they are each designated for specific types of piping systems.

For example, steam power generation plants, co-generation plants, and steam generating plants are designated as Power Piping and must comply with ASME B31.1 as a minimum. Refineries, petrochemical plants, gas oil separation plants (GOSP), and gas plants are designated as Process Piping and must comply with ASME B31.3 as a minimum. Transportation piping systems, such as cross country pipelines, water injection systems, and terminals for transporting and shipping crude oil and its derivatives, must comply with ASME B31.4 as a minimum. Gas or multi-phase service piping systems, such as cross country pipelines in gas service, flowlines in gas or crude oil service, and liquid sulfur transportation pipelines, must comply with ASME B31.8 as a minimum.

Additionally, the standard sets rules for selecting applicable Saudi Aramco Engineering Standards and/or Saudi Aramco Materials System Specifications that supplement the codes. This standard supplements the codes and defines additional design requirements for piping systems. The passage also specifies that shop fabricated skid mounted piping, such as metering skids, must follow the applicable code selected for the facilities to which they will be installed.

Code Break and Plot Limits

This section of the standard outlines guidelines for determining the code break, which refers to the location where the piping code changes from one code to another. The code break should be identified early in the piping system design process, and if it is not specified, safety, practicality, and economic impacts should be considered when selecting the location. The code break boundary between codes should be on the side of the more stringent code, resulting in the higher pipe class.

The standard recommends several locations for code breaks, including the plot limit boundary, emergency isolation valves near the perimeter fence, the isolation valve on the lateral line of an onshore scraper launcher receiver trap, and various locations for offshore piping code boundaries. It’s important to note that existing code breaks should not be altered to meet new requirements or match newly assigned code breaks within specific facilities, and any changes to the existing code breaks should be approved jointly by the Piping Standards Committee Chairman, Proponent Representative, Loss Prevention, PMT, and CSD through a letter of understanding.

General Design Basis of SAES-L-100 PDF Download

The general design basis for piping systems at Saudi Aramco includes several requirements and considerations. Design parameters per code shall be identified by the Design Agency responsible for designing the piping systems.

Piping systems shall not be designed for double contingency unless it is identified as a possibility based on HAZOP studies. The Contingent Design Conditions include uncontrolled shutdowns, improper operations, single device or function failures, fire in fire hazardous areas, and ambient conditions with an expected average return interval of less than 100 years.

Coincident unrelated contingencies or failures of more than one device shall be considered when specified in the SAES for specific circumstances. The piping system shall be mechanically capable of withstanding design conditions within the applicable Code requirements.

High Integrity Protection Systems (HIPS) shall be applied per SAES-L-310 or SAES-L-410 as applicable. Critical Piping includes piping that is part of vital plant equipment, essential for plant operation at design capacity, cannot be readily replaced, vulnerable to damage from fire or explosion, and in hydrocarbon service except lube oil and seal oil.
