Book Description
"The entry, control and release of air from pipelines is a major, though often, hidden problem in pipelines used for water supply, foul water drainage and effluent discharge. Considerable cost can be incurred in providing air valves and chambers, and in deepening trenches so as to provide the minimum gradients that are thought necessary to enable air bubbles and pockets to move towards the valves. This report is the first output of a research study commissioned by the Department of Trade and Industry (DTI), to be carried out between October 2003 and November 2005. The study is aimed at producing a guidance manual for designers and operators of pipelines in order to reduce the number and cost of problems caused by air in water and wastewater pipelines." -- p. iii.

Book Description
This book is concerned with the steady state hydraulics of natural gas and other compressible fluids being transported through pipelines. Our main approach is to determine the flow rate possible and compressor station horsepower required within the limitations of pipe strength, based on the pipe materials and grade. It addresses the scenarios where one or more compressors may be required depending on the gas flow rate and if discharge cooling is needed to limit the gas temperatures. The book is the result of over 38 years of the authors' experience on pipelines in North and South America while working for major energy companies such as ARCO, El Paso Energy, etc.

Book Description
Transmission Pipeline Calculations and Simulations Manual is a valuable time- and money-saving tool to quickly pinpoint the essential formulae, equations, and calculations needed for transmission pipeline routing and construction decisions. The manual's three-part treatment starts with gas and petroleum data tables, followed by self-contained chapters concerning applications. Case studies at the end of each chapter provide practical experience for problem solving. Topics in this book include pressure and temperature profile of natural gas pipelines, how to size pipelines for specified flow rate and pressure limitations, and calculating the locations and HP of compressor stations and pumping stations on long distance pipelines. - Case studies are based on the author's personal field experiences - Component to system level coverage - Save time and money designing pipe routes well - Design and verify piping systems before going to the field - Increase design accuracy and systems effectiveness

Book Description
Pneumatic Conveying Design Guide is a guide for the design of pneumatic conveying systems and includes detailed data and information on the conveying characteristics of a number of materials with a wide range of properties. This book includes logic diagrams for design procedures and scaling parameters for the conveying line configuration. It also explains how to improve the performance of pneumatic conveyors by optimizing, uprating, and extending the system or adapting it for a change of material. This book consists of 15 chapters divided into three sections and opens with an overview of the state of the art on pneumatic conveying, along with definitions of the terms used in pneumatic conveying. The next chapter describes the various types of pneumatic conveying systems and the parameters that influence their capabilities in terms of material flow rate and conveying distance. The discussion then turns to feeding and discharging of the conveying line; selection of a pneumatic conveying system for a particular application; and design procedures for pneumatic conveying system. The theory and use of compressed air in pneumatic conveying are also considered, along with the effect of material properties on conveying performance; troubleshooting; and operational problems and some solutions. The final chapter is devoted to the use of bench-scale test methods to determine the material properties relevant to pneumatic conveying. This monograph is intended for designers and users of pneumatic conveying systems.

Book Description
Piping and Pipeline Calculations Manual, Second Edition provides engineers and designers with a quick reference guide to calculations, codes, and standards applicable to piping systems. The book considers in one handy reference the multitude of pipes, flanges, supports, gaskets, bolts, valves, strainers, flexibles, and expansion joints that make up these often complex systems. It uses hundreds of calculations and examples based on the author's 40 years of experiences as both an engineer and instructor. Each example demonstrates how the code and standard has been correctly and incorrectly applied. Aside from advising on the intent of codes and standards, the book provides advice on compliance. Readers will come away with a clear understanding of how piping systems fail and what the code requires the designer, manufacturer, fabricator, supplier, erector, examiner, inspector, and owner to do to prevent such failures. The book enhances participants' understanding and application of the spirit of the code or standard and form a plan for compliance. The book covers American Water Works Association standards where they are applicable. - Updates to major codes and standards such as ASME B31.1 and B31.12 - New methods for calculating stress intensification factor (SIF) and seismic activities - Risk-based analysis based on API 579, and B31-G - Covers the Pipeline Safety Act and the creation of PhMSA

Book Description
Low or negative pressure transients (also called surge or water hammer) create temporary opportunities for external chemical and microbial contaminants at higher pressure to enter the water distribution system, creating potential health hazard and potential weakening of distribution pipes, leading to failure. This study investigates how such events as power outages, pump shutdowns, valve operations, main flushing, firefighting, and main breaks can create significant rapid, temporary drops in system pressure. The report offers useful recommendations for using surge models to optimally locate pressure monitors and to minimize the occurrence and impact from low- and negative-pressure transients.
