Explosion-proof equipment plant
Flexible armored cable elements MGR (explosion-proof flexible metal conduit, hoses) are used for connection of equipment and devices subject to strong vibration (such as electrical motors, pumps, fans etc.), for protection of vulnerable electrical cables, wires and fiber optics.
Material flexible conduit - cold-resistant dire retardant polymer armored with stainless steel wire.
Scope of application - hazardous indoor and outdoor areas in accordance with explosion protection marking, GOST 30852.13-2002 (IEC 60079-14:1996), dangerous production facilities of I, II, III, IV hazard classes under supervision of Rostekhnadzor and national supervisory bodies of the CU and the CIS countries.

INCORRECT INSTALLATION |
|
CORRECT INSTALLATION |
 |
Do not pull flexible element SP — unravel it carefully |
 |
 |
Do not twist flexible element SP — install it without twisting |
 |
 |
Make sure that length of flexible element SP is not too short |
 |
 |
Avoid excessive bending of SP flexible element, use ELM fittings. |
 |
 |
Do not move SP flexible element across the surface, move only along the axis |
 |
 |
Try not to bend SP flexible element, use the template |
 |
 |
If excessive movement along the axis occurs, do not install SP flexible element along the straight line, use U-bending |
 |
 |
Avoid twisting when the equipment is not on the same line, install only in one plane |  |
 |
Avoid bending of SP flexible element in a suspended state, use the reel |
 |
 |
Avoid excessive bending of ends of SP flexible element, use ELM fittings |
 |
 |
Avoid oscillation along the axis, install SP flexible element vertically to the direction of the motion |
 |
 |
Avoid oscillation from different directions to one SP flexible element, install several conduits |
 |
 |
Do not allow SP flexible element to move only in one direction, move it to the center in order to distribute the motion in both directions |
 |
 |
Prevent oscillation along the axis, install SP flexible element vertically to the direction of the motion |
 |
 |
Prevent side vibrations, install SP flexible element at 90° angle |
 |
 |
Avoid bending – bending of SP flexible element and oscillation must occur in one plane |
 |
 |
Prevent excessive bending of SP flexible element ends, use ELM fittings |
 |
 |
Do not install longer SP flexible elements; install SP flexible elements of accurate length |
 |
 |
The distance must not be too long, use accurate dimensions |
 |
 |
Prevent bending at angle vibrations, all SP flexible element motions must occur along the axis only |
 |
 |
Do not pull SP flexible element along the floor without protection. Prevent damage with the help of protective rug |
