The minimum temperature in the natural universe is 2.7 K. Laboratory refrigerators can reach temperatures in the microkelvin range. Modern industrial refrigerators cool foods at 200 K, whereas space mission payloads must be capable of working at temperatures as low as 20 K. Superconducting magnets used for NMR work at 4.2 K.
Hence the properties of materials must be accurately known also at cryogenic temperatures.

This book provides a guide for engineers, physicists, chemists, technicians who wish to approach the field of low-temperature material properties. The focus is on the thermal properties and a large spectrum of experimental cases is reported. The book presents updated tables of low-temperature data on materials and a thorough bibliography supplements any further research.
Key Features include:

-Detailed technical description of experiments
-Description of the newest cryogenic apparatus
-Offers data on cryogenic properties of the latest new materials
-Current reference review

The birth of this monograph is partly due to the persistent efforts of the General Editor, Dr. Klaus Timmerhaus, to persuade the authors that they encapsulate their forty or fifty years of struggle with the thermal properties of materials into a book before they either expired or became totally senile. We recognize his wisdom in wanting a monograph which includes the closely linked properties of heat capacity and thermal expansion, to which we have added a little ‘cement’ in the form of elastic moduli.

There seems to be a dearth of practitioners in these areas, particularly among physics postgraduate students, sometimes temporarily alleviated when a new generation of exciting materials are found, be they heavy fermion compounds, high­ temperature superconductors, or fullerenes. And yet the needs of the space industry, telecommunications, energy conservation, astronomy, medical imaging, etc. , place demands for more data and understanding of these properties for all classes of materials – metals, polymers, glasses, ceramics, and mixtures thereof.

There have been many useful books, including Specific Heats at Low Tempera­ tures by E. S. Raja Gopal (1966) in this Plenum Cryogenic Monograph Series, but few if any that covered these related topics in one book in a fashion designed to help the cryogenic engineer and cryophysicist. We hope that the introductory chapter will widen the horizons of many without a solid state background but with a general interest in physics and materials.

“هندبوک شیر اطمینان” یک منبع حرفه‌ای برای مهندسین طراحی، فرآیند،‌ نیروگاه و تعمیر و نگهداری که با جریان سیال و سیستم‌های حمل و نقل در صنایع فرآیند کار می‌کنند، طراحی شده است و مواد شیمیایی، نفت و گاز، آب،‌ کاغذ و خمیر کاغذ، غذا و محصولات زیستی و سکتورهای انرژی را پوشش می‌دهد.
این کتاب نیاز مهندسانی که مسئولیت‌هایی برای تعیین‌کردن،‌ نصب و راه‌اندازی، بازرسی یا نگهداری شیرهای اطمینان و سیستم‌های کنترل جریان را دارند، پوشش می‌دهد.

The Safety Valve Handbook is a professional reference for design, process, instrumentation, plant and maintenance engineers who work with fluid flow and transportation systems in the process industries, which covers the chemical, oil and gas, water, paper and pulp, food and bio products and energy sectors.

It meets the need of engineers who have responsibilities for specifying, installing, inspecting or maintaining safety valves and flow control systems.

It will also be an important reference for process safety and loss prevention engineers, environmental engineers, and plant and process designers who need to understand the operation of safety valves in a wider equipment or plant design context.

• No other publication is dedicated to safety valves or to the extensive codes and standards that govern their installation and use. A single source means users save time in searching for specific information about safety valves.
• The Safety Valve Handbook contains all of the vital technical and standards information relating to safety valves used in the process industry for positive pressure applications.
• Explains technical issues of safety valve operation in detail, including identification of benefits and pitfalls of current valve technologies.
• Enables informed and creative decision making in the selection and use of safety valves.
• The Handbook is unique in addressing both US and European codes:
– covers all devices subject to the ASME VIII and European PED (pressure equipment directive) codes;
– covers the safety valve recommendations of the API (American Petroleum Institute);
– covers the safety valve recommendations of the European Normalisation Committees;
– covers the latest NACE and ATEX codes;
– enables readers to interpret and understand codes in practice.
• Extensive and detailed illustrations and graphics provide clear guidance and explanation of technical material, in order to help users of a wide range of experience and background (as those in this field tend to have) to understand these devices and their applications.
• Covers calculating valves for two-phase flow according to the new Omega 9 method and highlights the safety difference between this and the traditional method.
• Covers selection and new testing method for cryogenic applications (LNG) for which there are currently no codes available and which is a booming industry worldwide.
• Provides full explanation of the principles of different valve types available on the market, providing a selection guide for safety of the process and economic cost.
• Extensive glossary and terminology to aid readers’ ability to understand documentation, literature, maintenance and operating manuals.
• Accompanying website provides an online valve selection and codes guide.

H.P. Garg Centre of Energy Studies Indian Institute of Technology Hauz Khas, New Delhi 110 016 India Heating of water using solar energy is not new and by using a little science and technology in it, the solar energy can be utilized more effectively and economically for heating the water both for domestic and industrial applications. Solar Water Heaters are popular for the last three decades in countries like USA, Australia, Israel, Japan, India. This is the only solar energy application which is commercially, technic­ ally and economically viable and has been studied for more than 30 years in many countries. Technical advances in solar water heating have been very rapid in the last 30 years. These are becoming popular not only for domestic use but for large establishments like hostels, hotels, hospitals, industries such as Textile, Paper and Food Processing and even in heating of swimming pools in winter. In few instances the cost of solar water heating systems may be higher than those operated by electricity, gas or other fuel but over a period of time this is more than recovered by the savings in the cost of operations and maintenance.
