Book Description

Gas Pipeline Hydraulics
Gas Pipeline Hydraulics


    In your day-to-day planning, design, operation, and optimization of pipelines, wading through complex formulas and theories is not the way to get the job done. Gas Pipeline Hydraulics acts as a quick-reference guide to formulas, codes, and standards encountered in the gas industry. Based on the author's 30 years of experience in manufacturing and the oil and gas industry, the book presents a step-by-step introduction to the concepts in a practical approach illustrated by real-world examples, case studies, and a wealth of problems at the end of each chapter.

    Avoiding overly complex equations and theorems, Gas Pipeline Hydraulics demonstrates the calculation of pressure drop using various commonly accepted formulas. The author extends this discussion to determine total pressure required under various configurations, the necessity of pressure regulators and control valves, the comparative pros and cons of adding compressor stations versus pipe loops, mechanical strength of the pipeline, and thermal hydraulic analysis. He also introduces transient pressure analysis along with references for more in-depth study. The text concludes with the economic aspects of pipeline systems.
