Shipping and Handling
Materials for piping systems shall be prepared and marked for shipment and
storage as specified. Each piece of piping fabrication shall be identified
with a piece mark number which is repeated on each end of section and on
each branch. Ship gaskets to the jobsite tagged with size, material, and
pressure rating. Loose parts such as nuts, bolts, and gaskets shall be
packaged for outdoor storage. Protect flanges with plywood or tempered
hard fiberboard covers sealed and bolted to the flange with not less than
four bolts. Protect threaded connections with thread protectors. Protect
small connections with plastic inserts pressed into the connection and
sealed with waterproof tape. Ship hangers to the jobsite with each hanger
assembly individually bundled and tagged with the hanger assembly number.
Coat-threaded connections with a suitable rust-preventative compound. Ship
valves to the jobsite tagged with the appropriate valve number
corresponding to the valve list. Ship valves with suitable covers to
prevent entrance of foreign material into valve body. Protect valve
threads, stems, and handwheels from damage.

moderately abrasive conductive dusts and high humidity are present. Motors
shall be self-ventilated. Motors shall be designed for full-voltage
starting. Indoor motors shall be suitable for continuous operation at an
ambient temperature of 50 degrees C 122 degrees F. Outdoor motors shall be
suitable for continuous operation at any ambient temperature from minus 10
degrees C to plus 40 degrees C 14 degrees F to 104 degrees F. Motors shall
have squirrel-cage rotors. The nameplate power rating of each motor at 1.0
service factor shall equal or exceed the power required to drive the
