Commercial Building Fire Sprinkler Hose
Commercial building fire sprinkler hose assembly consists of a flexible hose,inlet fitting for connection to the branch line and an outlet fitting for connection to the sprinkler.These flexible hose with fittings are intended to be installed using the anchoring devices referenced in the manufacture’s installation instructions.Flexible hose length is limited to a maximum of 2000mm so as to minimize the potential for inadequate support and undesirable movement of a sprinkler after installation.
The fire sprinkler hoses have high flexibility or limited flexibility.The fire hoses having high flexibility are intended for use in applications where frequent movement between the two ends of the hose is expected after installation. Fire sprinkler hoses having limited flexibility are intended for use in applications where little or no movement between the two ends is expected after installation.
