General
Description
The GRINNELL G-FIRE Figure 577
Grooved Rigid Couplings provide a
rigid joint by rmly gripping along the
full circumference of the pipe grooves.
Figure 577 couplings are a proven
dependable method of joining pipe
and are an economical alternative to
welding, threading, or using anges.
Figure 577 couplings are rated at pres-
sures up to 350 psi (24, 1 bar) depend-
ing on pipe size and wall thickness
when used in re protection service
applications. For more information,
see Table A.
NOTICE
The GRINNELL G-FIRE Figure 577
Grooved Rigid Coupling described
herein must be installed and main-
tained in compliance with this docu-
ment, as well as with the applicable
standards of the Approval agency, in
addition to the standards of any other
authorities having jurisdiction. Failure
to do so may result in serious personal
injury or impair the performance of
these devices.
Never remove any piping component
nor correct or modify any piping defi-
ciencies without first de-pressurizing
and draining the system. Failure to do
so may result in serious personal injury,
property damage, and/or impaired
device performance.
It is the designer’s responsibility
to select products suitable for the
intended service and to ensure that
pressure ratings and performance
data are not exceeded. Material and
gasket selection should be verified to
be compatible for the specific applica-
tion. Always read and understand the
installation instructions.
The owner is responsible for main-
taining their mechanical system and
devices in proper operating condition.
The installing contractor or device man-
ufacturer should be contacted with any
questions.

Care and
Maintenance
The GRINNELL G-FIRE Figure 577
Grooved Rigid Coupling must be main-
tained in accordance with this section.
Before closing a re protection system
main control valve for maintenance
work on the re protection system
that it controls, obtain permission to
shut down the affected re protection
system from the proper authorities
and notify all personnel who may be
affected by this decision.
After placing a re protection system
in service, notify the proper authorities
and advise those responsible for moni-
toring proprietary and/or central station
alarms.
The owner is responsible for the inspec-
tion, testing, and maintenance of their
re protection system and devices in
compliance with this document, as well
as with the applicable standards of the
NATIONAL FIRE PROTECTION ASSO-
CIATION, such as NFPA 25, in addition
to the standards of any authority having
jurisdiction. Contact the installing con-
tractor or product manufacturer with
any questions. Any impairments must
be immediately corrected.
Automatic sprinkler systems are rec-
ommended to be inspected, tested,
and maintained by a qualied Inspec-
tion Service in accordance with local
requirements and/or national codes.
