FLEXIBLE CONNECTORS
SWEAT END METAL BRAIDED
FLEXIBLE CONNECTOR
Flexible connectors are used to absorb thermal and seismic movement,
absorb hydraulic shock, provide vibration and noise dampening, ease
installation and correct minor misalignment of piping and components.
They come in a variety of sizes, materials, and connection ends for
numerous applications.
The inner hose is an annular (bellows) design. An annular hose is better
suited for pump connections because it can better sustain torsion stress
due to longitudinal expansion from rises in pressure. Metal wire braid on a
hose assembly restrains against hose elongation under higher pressures
and acts to dampen vibration. A heavy braid also increases abrasion
resistance. Optimal braid coverage will contain the core under pressure
and reduce the possibility of twisting and squirming.
The use of braided metal connectors for applications such as pumps,
compressors and other mechanical equipment can enhance the overall
operation of a system.
Braided connectors have the advantages of:
• Longer service life
• Increased pressure capacity
• Greater fatigue resistance due to ex
• Increased temperature capacity of media
• Greater protection of annular hose
• Acceptance of thermal expansion
• Assembly must have 100% chloride free
ux and be thoroughly cleaned after each
installation
