Abstract
Pipes are silent workers, conveying fluid or allowing air to enter 0( to leave a space, and are the means by which many control systems operate. Pipes penetrate almost every enclosed space, as well as the shell both .above and below the waterline, and the weather deck. Everyone knows about the effect of corrosion on a ship’s hull, but few people consider the effect of corrosion on piping. Pipes pose a hidden danger, a danger that is often forgotten about. Chapter one has a brief introduction to piping system in ships, Chapter two starts with discussing the ships’ piping systems and classifies it to machinery piping system and hull piping system. Machinery piping system also will be classified to fuel oil system, lubricating oil system, cooling system and starting air system. Hull piping systems will be classified to ballast system, bilge system, fire fighting system, sewage system and domestic system, also there are different systems which may be used according to ship function like hydraulic piping system, steam piping system and cargo system. Chapter three deals with pipe design by using suitable pipe material and pipe dimensions, it discusses different methods to identify the pipe either by coloring the whole pipe or using marking taps. Also it discuss the different auxiliaries for pipe such as connection to pumps, pipe joint, pipe clips and supports and valves. Chapter four has the detailed description for the role of classification societies for pipe inspection during different surveys such as annual survey, intermediate survey and renewal survey for different types of ships. Pipes corrode internally and externally, chapter five discuss the different causes of pipe failure such as uniform corrosion, pitting corrosion, abrasion and erosion, fatigue damage, galvanic corrosion, graphitic corrosion, water hammer, mistakes in alignment, low temperate and pipe expansion. Chapter six gives a full description of dealing with pipe failure. pipe maintenance and repair. Chapter seven deals with a case study carried out to design a fresh water piping system according to Germanischer Lloyds (GL) Rules, calculation of tank capacities andcalculation friction losses in piping system.
