Product Description

One sphere rubber flexible coupling: DN25mm-DN3600mm

Thanks to the rubber alone characteristics, single sphere rubber bellow expansion joint is the highest utilization of rubber, most steady efficiency product at the instant.
On the basis of torsion displacement, transverse displacement, angular displacement, the axial compression, the axial elongation, deflection displacement, and so on, one spherical rubber joint&rsquos glue amount is little, stability is very high, and provider existence is prolonged., so it can be widely employed.

Attribute Characteristic of single sphere rubber flexible coupling:

(1)Tiny volume, light-weight in bodyweight, extremely very good versatility, Ease installation and servicing.
(2)Transverse displacement, axial displacement, angular displacement
(3)Decrease sounds, shock absorption

Assemble Guide

1. In the course of pipe building, the rubber enlargement joint shall be retained natural, do not deform the product purposely when putting in.

2. For the duration of setting up flange loosing rubber enlargement joint, the maximizing ring (jutted interior metal wire rope) of spherical two finishes shall be entirely set up within the flange slot so as to avoid balls to break away from flanges when pipes bear pressure. For the duration of putting in bolts, screw down symmetric six/four bolts and maintain balls and flanges remaining in get.

three. When connecting rubber adaptable coupling and pipe flange, the bolt pole shall lengthen to the pipe flange so as to avert from crushing or pricking the coved screw thread expanding due to the fact of stress, all bolts shall be pressures and screwed down and word congruously. If the encompassing circumstance is bad, spring washer and flat gasket shall be added to avoid bolts from loosing.

4.If arch/high arc rubber couplings are tailored(for 6-angle bolt are not able to go by means of flange hole),double-head bolts shall be utilized and try to decrease spherical screw thread jut and stay away from crushing balls expanding under stress and stop early hurt of rubber.

five. When frequently use the rubber growth couplings or close to h2o (oil) pump nozzles, end block shall be included on the two finishes of flanges so as to decrease the influence on pump and pipe brought on by the duration adjustments of rubber joint.

six. When adapting more than DN1000 rubber versatile coupling, some length limited pipe shall be created on one flange end so as to help installation and reduce labor toughness. Following connecting rubber enlargement couplings and the brief pipe and other pipe, weld the limited pipe and pertinent pipe collectively.

7. In buy to get rid of the radial deviation fashioned by brief pipe welding, use round steel or other related metallic to temporarily weld flanges on pipe&rsquos two finishes and make the rubber growth joint and flange be a metal physique. After welding, eliminate the welding again and keep the rubber joint natural as typical.

8. When welding metal and flange, remember to cover the rubber growth couplings with shielding and stop from burning balls.
