SAES-L-620SAES-L-620 Design of Nonmetallic Piping in Hydrocarbon and Water Injection Systems
SAES-L-610 is a Design Standard that establishes requirements and limitations for the design, installation, and testing of nonmetallic piping in oily water services. It specifically focuses on Reinforced Thermosetting Resins (RTR) pipe and pipeline.
The standard applies to various applications including flowlines, testlines, and water injection systems. It is intended for use in buried piping systems and, with prior approval, above-ground piping systems. It covers both high pressure piping systems (MAOP ≥ 500 psi) and low pressure piping systems (MAOP < 500 psi).
SAES-L-610 is applicable to location Class 1 for flowlines, testlines, and water injection systems. It also includes road crossings in location Class 2 with a population density index of 10 or less. The standard provides recommended temperature limits for reinforced thermosetting resins pipe in Table 1.2-1.
However, there are certain services excluded from the scope of this standard. In-plant piping systems, pipelines in location Class 2 with a population density index of more than 10, and pipelines in locations Class 3 and 4 are not covered. Additionally, potable water systems, fire and raw combined water systems, irrigation water systems, well water systems, and gravity draining systems in Saudi Aramco facilities have their own specific design standards.
It is important to adhere to SAES-L-610 when designing nonmetallic piping systems for oily water services, ensuring compliance with the requirements and limitations specified in the standard.
Pipeline Optimization Study
When planning a new application of RTR pipeline, a comprehensive study must be conducted to evaluate its safety, technical feasibility, and economic viability. This study should include a Life Cycle Cost Analysis, which examines the total costs associated with the pipeline over its entire lifespan. The study should be performed no later than the Project Proposal stage and should cover the following key aspects:
a) Determining the appropriate pipe diameter, wall thickness, and material type and grade for the specific application.
b) Evaluating different pipeline routing options and construction methods, such as aboveground or buried installation, and assessing their impact on initial capital investment, ongoing operation, and maintenance expenses.
c) Classifying the pipeline area based on factors such as environmental conditions, land use, and proximity to sensitive areas.
d) Analyzing the maximum allowable operating pressure, available inlet pressure, and minimum required delivery pressure to ensure the pipeline can operate safely and efficiently.
e) Considering future expansion requirements to accommodate potential growth or changes in demand.
f) Assessing the constructability of the pipelines, including factors like ease of installation, availability of equipment and materials, and potential challenges during construction.
g) Determining the design flow rate, considering both current needs and potential future requirements, and taking into account velocity limitations imposed by the fluid composition and flow patterns, particularly in the case of multi-phase fluids.
h) Developing a Management of Change (MOC) package as required by the Saudi Aramco Safety Management System (SMS) Element 5. This package ensures that any modifications or updates to the pipeline are thoroughly reviewed and approved to maintain safety and compliance.
i) Calculating the Rupture Exposure Radius (RER) unless the default RER values specified in SAES-B-064 are used. The RER calculation considers factors such as the pipeline’s characteristics, operating conditions, and the population density index of the surrounding area. This information is used to determine the appropriate location class for the pipeline.
It’s important to note that production pipelines carrying gas or crude may not require a detailed pipeline optimization study. For such pipelines, it is recommended to consult the Production & Facilities Development Department of E&P, as they are responsible for the development of these specific pipelines and can provide guidance based on their expertise.
Additionally, pipeline hydraulic and surge studies should be conducted as needed and in accordance with SAEP-27 and SAEP-363. These studies assess the hydraulic behavior of the pipeline, including factors such as flow rates, pressure fluctuations, and surge events, to ensure the pipeline’s design can effectively handle these dynamics and maintain safe and reliable operation.
