Section Eleven
TECHNICAL
INFORMATION
As we stated in the Preface of this book, its intention is solely for
the estimation of labor and is not intended for the design of pip-
ing. Therefore, this section has been held to a minimum and
includes only information that we feel will benefit the estimator
in the preparation of his estimate.
Included in this section are tables showing the circumferences of
pipes for welding purposes, the amount of materials needed for
insulation, the weights of pipe, fittings and valves and methods of
hanging and supporting pipe and fittings.
We wish to acknowledge and to express our appreciation to the
Grinnell Company, Inc., of Providence, Rhode Island, who has so
graciously allowed us to reproduce the following tables.
