Screw pipe clamp GRINNELL G-FIRE Figure 705

The GRINNELL G-FIRE Figure 705 Grooved Flexible Couplings, when properly installed, provide a dependable method of joining pipe, allowing for angular and linear deflection, thermal expansion and contraction, and misalignments of the pipe. Figure 705 couplings are rated at pressures up to 300 psi (20,7 bar) depending on pipe size and wall thickness when used in fire protection service applications. (See Table A.) The GRINNELL G-FIRE Figure 705 Grooved Flexible Coupling described herein must be installed and maintained in compliance with this document and with the applicable standards of the NATIONAL FIRE PROTECTION ASSOCIATION (NFPA), in addition to the standards of any authorities having jurisdiction. Failure to do so may impair the performance of these devices. Never remove any piping component nor correct or modify any piping deficiencies 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 application. Always read and understand the installation instructions. The owner is responsible for maintaining their fire protection system and devices in proper operating condition. Contact the installing contractor or sprinkler manufacturer with any questions.
