Treloar R.D. Gas Installation Technology

2nd edition. John Wiley & Sons, Ltd., 2010. - 498 p.
This book aims to cover all areas of the gas industry that the operative is likely to encounter. It has purposely grouped together all the various aspects of gas work to include natural gas and LPG with domestic and commercial installations. This may seem strange to some, but it overcomes the problem of repeating topics and cross-checking and allows it all to be contained within the one book.
Much of the work undertaken by the gas engineer follows the same generic principles. The gas principles and processes that are used every day and the type of installation have little or no bearing on the way in which the work is completed. There are variances, hence the need sometimes to identify specific installation types; this has been done throughout the book, where necessary.The Gas IndustryThe Gas Industry.
