1. Definition:

A flexible stainless steel sprinkler hose with fittings is particularly suited for use in suspended ceiling applications and intends for use in hydraulically-designed sprinkler systems between the branch line and sprinkler. Its assembly consists of a flexible hose, inlet fitting for connection to the branch line and an outlet fitting for connection to the sprinkler. This type of product having limited flexibility, is intended for use in applications where little or no movement between the two ends is expected after installation. This unit is equipped with the material for sealing on the connect part of the reducer to have air tightness, and designed to resist the corrosion from hydrogen chloride, nitric acid gas and for the gas of duct inner not to leak into indoor. Ideal projects are offices, schools, libraries, hospitals, and shopping malls.

2. Advantages:

2.1 Reinstall sprinkler at your convenience:
Without decompressing pipelines or resetting system, it could go on reinstalling sprinkler.

2.2 Facilitate installation:
Saves time and costs since the system can be installed in false ceilings without cutting and threading pipes associated with installing a drop, armover, and elbows.

2.3 Adjustable installation:
Adjustable height and sprinkler alignment and perfect center-of-tile and aesthetic uniformity.

2.4 Flexible construction:
Misalignment between pipe and ceiling grid is able to be resolved using sprinkler flexible hose.

2.5 Whole structure design:
Site welding is not necessary. No leakage.

2.6 Reduce dust and pollutants in the clean room area:
Our factory is responsible for assembly and tests without the extra sealant or coating at site.

3. Principle of Usage:

3.1 Allows for independent motion (sway) between ceiling grid and water main to accommodate filter vibration and during possible seismic activity.

3.2 Acceptable for use in a return-air plenum.

3.3 Eliminates ceiling stress/leaks due to misaligned hard-pipe installation changes due to reconfiguration of tool layout.
