14.9 Length Cutting and Assembly Information

Cutting of spirally reinforced plastic hoses

Rip the hose open, preferably with a ragged knife. Intersect the supporting spiral with pliers.

Cutting of the metal hoses 375 ? 377

Fix the ends with rivets or by soldering. Lever out the profile with a screw driver. Cutting of the protruding profile with a shear blade or diagonal cutting pliers.

Cutting of bare or plastic coated cable protection hoses of metal (types 101 ? 109)

By bending:
Cut the plastic mantle (if existing) Bend the metal hose Cutting of the protruding profile with a shear blade or diagonal cutting pliers.
By intersecting:
Cut the plastic mantle (if existing) Intersect axially with a small carbide-tipped saw blade. Separate the ends from each other by turning apart.
By sawing:
Cut the metal hose on a belt saw at high cutting speed.

Grounding for protection against electrostatic charging

The correct and continuous grounding of all installation components (including hoses and with hose ends connected accessories) largely protects against process troubles and ignition of explosive atmospheres. Please note our corresponding data sheet electrostatic charging.
Expose the spiral, bend it to the inside and mount it onto a conductive socket. Expose the spiral and fix it, for example, by a rivet or screw.

Strip insulation of AIRDUC® hoses

Cut hose with a fine-toothed knife along the steel wire. Either pull off plastic piece with a piece wire stripper or remove it more convenient with a special dismantle tongs.

Sufficient tightness by assembling

A sufficient tightness can in the main only be achieved by our own developed spiral hose clamps. Emerging media can endanger man and environment, trouble the process and often impair the efficiency of an application.
Tight assembly by the use of the original accessories. Significant leakage by the use of conventional hose clamps.
