Excerpts from the 7th edition of the Travelers Indemnity book, Boiler Economy:
From the Preface:
The Travelers Indemnity Company employs a large force of expert inspectors, whose knowledge and experience are always at the command of our assured; and the services that these men render are worth far more than the cost of the insurance. Problems that require special study, and call for more time and consideration than any individual visiting inspector can devote to them, are laid before the staff of the Engineering and Inspection Division of the Company, at its Home office in Hartford, Connecticut...
The facilities of the Travelers Engineering and Inspection Division are broad and complete in every respect. Engineers of national reputation are at its head, and under their direction expert services of every needful kind are rendered by well organized departments, in charge of competent men who are admitted authorities in their own special lines.
For patrons who contemplate putting in new boilers, or changing their present boiler plants in other ways, The Travelers is prepared to furnish practical specifications and plans, showing the most improved designs, and the best methods for executing the work in all its details…
Section 78 of the book:
COVERINGS FOR PIPES AND BOILERS: The coverings that are used to check radiation from pipes and boilers should have good heat-insulating properties. Non-conducting coverings should be of such a nature that leaks from pipes or from the roof of the boiler house will not damage them seriously, and they should not be made of materials that are likely to char from heat. In selecting them, attention should be given, not only to the cost of the material, but also to its heat-insulating power, as determined by experiment.
Coverings upon pipes that convey steam or hot water under pressure should be applied in such a way that they can be removed readily for repairs or inspections,-particularly where the pipes enter fittings of any kind. In the event of a leak at these places, it will then be possible to examine the pipe and make the needed repairs at materially less expense than would be involved if the covering were put on without regard to this contingency.
Travelers inspectors are at the service of our assured at all times, to give counsel upon any points that relate to the safety or economy of the boilers…
The concluding section of the book, Section 106:
INSPECTION AND INSURANCE: Every boiler owner should insure his boilers with the best company he can find; and no other company is as well prepared as The Travelers, to render technical services of a useful, practical character. Its engineers and inspectors are men of wide mechanical experience, with a sound and thorough knowledge of boiler management; and you are cordially invited to submit to them any question or problem that may arise in your plant, bearing upon the safety or economy of your steam boilers. Inquiries should be addressed to The Travelers Indemnity Company, Hartford, Connecticut.
