Our Advantages

Safe & Reliable
All the parts fexible hoses are manufactured in corrosion resistant and high-powered stainless steel with 100% leak tested prior to leaving the factory and the environmental temperature resistance being as high as 107ºC/225ºF
Easy and Quick installation 
No special tools are required and It only needs the simple use of wrench, screw driver and pipe sealing tape, etc, in the installation with the minimal amount of time. The fexibility hose can be adjusted based on the installation space and can also be combined with 90' elbow, which allows hose to be fxed in limited installation space.
Economizing on cost With the unique connection mode of fexible hose, the MECH brand is much more time and cost saving and with no need of any machine against traditional hard pipe system installation.
Environmental Friendly
The flexible hose can be re-shaped and relocated to suit the final sprinkler location on the ceiling without draining the system, avoiding the pipe wasted by the inaccurate measurement. No sprinkler displacement even after high pressure test and eliminating the need for an oversized ring around the sprinkler.
Seismically
The stainless steel hose can absorb seismic shock, and protect the sprinkler system to maintain normal operation in the case of an earthquake.

Installation

A.Connect Inlet Nipple
Use pipe wrench to screw the Inlet Nipple into the branch outlet interface on water supply pipeline,use pipe sealant (tape or pipe glue etc.) to seal and apply tightening torque of approx.50N·m/35ft-lbs.Then tighten the Hexagon Slip Nut with 28N·m/20ft-lbs to ensure sealing performance.

B. Fix bracket set
Attach side brackets to the main-rail of the T-bar grid and cross the square bar through 2 side brackets,with the center bracket in the middle.Tighten all fixing bolt on the side brackets with 4N·m/3ff-lbs.

C. Bending &Locating
Bend the Flexible Hose body as desired (according to Technical Specification of each style of flexible hoses) and locate the Discharge Nipple into the center bracket.Tighten the bolts on center bracket with 4N·m/3ft-lbs after the proper location of sprinkler head has been found.

D. Connect Discharge Nipple
Tighten the Slip Nuts with 28N·m/20ft-lbs and install sprinkler head to Discharge Nipple by following the sprinkler manufacture's installation instructions. Finally test leak in according with NFPA guidelines.
