Water systems piping consists of pipes, valves, fittings, pumps, and associated appurtenances that make up water transportation systems. These systems may be used to transport fresh water or nonpotable water at room temperatures or at elevated temperatures. In this chapter we will discuss the physical properties of water and how pressure drop due to friction is calculated using the various formulas.

Pipe Flow-Friction Factor Calculations with Excel, Course
Several kinds of pipe flow calculations can be made with the Darcy- Weisbach equation and the Moody friction factor. These calculations can be conveniently carried out with an Excel spreadsheet. Many of the calculations require an iterative solution, so they are especially suitable for an Excel spreadsheet solution. This course includes discussion of the Darcy- Weisbach equation and the parameters in the equation along with the U.S.
and S.I. units to be used. Example calculations and sample Excel spreadsheets for making the calculations are also included. This course is intended primarily for civil engineers, mechanical engineers, chemical engineers, and environmental engineers. After completing this course you will be able to make calculations with the Darcy Weisbach equation and the Moody friction factor equations to calculate several different unknown parameters when sufficient input data is provided. You will also be prepared to use Excel spreadsheets to efficiently make the calculations.

Difficult to Pig Pipelines
Pigging : A widely utilized process which is the act of propelling a properly sized spherical or cylindrical device through the interior of a pipeline by manipulating the pressure & flow of the existing media, or by artificially introduced media or by mechanically pulling the device through the pipeline for the
specific purpose of cleaning, inspecting or distributing inhibitor throughout the pipeline.

Introduction to Piping Design
• As per Merriam Webster dictionary , the pipe is a long tube or hollow body for conducting a liquid, gas, or finely divided solid.
• Technically : The pipe Is a beam , which acts as pressure vessel and transfer fluids.

Cathodic Protection Part 1 – Pipelines
SA Water is responsible for operation and maintenance of an extensive network of buried pipelines. Cathodic Protection (CP) is applied to a large proportion of those buried assets which assists with the management of external pipeline corrosion and is therefore and an important asset management tool to greatly increase asset life. This Standard has been developed to assist in the design, maintenance, construction, and management of SA Water’s pipeline CP infrastructure. The purpose of this Standard is to detail the requirements for each phase of a pipeline CP project from design, construction and commissioning, to maintenance and monitoring to ensure a consistent approach is achieved independent of the delivery model of a project, its location, project ownership or other influences.

Basic Pipe Stress Analysis Tutorial
It is common practice worldwide for piping designers to route piping by considering mainly space, process and flow constraints (such as pressure drop) and other requirements arising from constructability, operability and reparability. Unfortunately, pipe stress analysis requirements are often not sufficiently considered while routing and supporting piping systems, especially in providing adequate flexibility to absorb expansion/contraction of pipes due to thermal loads. So, when “as designed” piping systems are handed-off to pipe stress engineers for detailed analysis, they soon realize that the systems are “stiff” and suggest routing changes to make the systems more flexible. The piping designers, in turn, make changes to routing and send the revised layout to the pipe stress engineers to check for compliance again. Such “back and forth” design iterations between layout and stress departments continue until a suitable layout and support scheme is arrived at, resulting in significant increase in project execution time, which, in turn, increases project costs. This delay in project execution is further worsened in recent years by increased operating pressures and temperatures in order to increase plant output; increased operating pressures increase pipe wall thicknesses, which, in turn, increase piping stiffnesses further. Such increased operating temperatures applied on “stiffer” systems increase pipe thermal stresses and support loads. So, it is all the more important to make the piping layout flexible at the time of routing.

Inspect New Piping
Piping systems are like arteries and veins in the oil industry. Piping systems comprise of pipes, flanges, bolting, gaskets, valves etc. They also include pipe hangers, supporting elements and other items necessary to prevent over pressurization and over stressing of the pressure containing components. Hence, one can say that pipe section when fitted with valves and other mechanical equipment and properly supported by hangers and supports are called piping.

Flow Measurement in Pipes and Ducts
This course is about measurement of the flow rate of a fluid flowing under pressure in a closed conduit. The closed conduit is often circular, but also may be square or rectangular (such as a heating duct) or any other shape. The other major category of flow is open channel flow, which is the flow of a liquid with a free surface open to atmospheric pressure. Measurement of the flow rate of a fluid flowing under pressure, is carried out for a variety of purposes, such as billing for water supply to homes or businesses or, for monitoring or process control of a wide variety of industrial processes that involve flowing fluids. Several categories of pipe flow measurement devices will be described and discussed, including some associated calculations.
