Preface

There are valves everywhere, including in your home’s plumbing. In order to drink water in the kitchen, we must open a valve. The same is true to operate offshore pipelines. The most significant valves in offshore pipelines are discussed in this book. If these valves fail, oil and gas will not be able to be transported to customers and the society will be left without enough energy for heating, cooking, and transportation. A reader can be knowledgeable about the most critical valves on the offshore platform, including their design aspects, material selection, failure prevention mechanisms, and environmental protection measures. 

Pipeline valves are discussed in this book in terms of design, production, testing, coating, preservation, packing, lifting, transportation, and safety considerations. On the offshore platform, a pipeline valve is the largest, heaviest, and most essential valve. A recent project in Norway called for a 38" CL1500 ball valve with a weight of almost 70 kg and a height of over four meters. If pipeline valves fail, many negative consequences may ensue, such as the loss of expensive assets and production, environmental pollution, and the loss of human life.

Thus, it is imperative to design these valves accurately with special considerations aimed at minimizing the possibility of leakage into the environment. Furthermore, it is vital to design these valves in such a way as to conserve weight and space on the platforms. Different aspects of design are discussed in this book, including material selection, wall thickness calculations, weight reduction of the body and bonnet, using a double isolation and bleed seat design to reduce seat leakage, using seat scrapers and seat retraction mechanisms, cylindrical nuts, etc. Typically, these valves are welded to the pipeline using special welding techniques to bond two dissimilar materials. In this book, the welding process is explained in detail.
