CENTRATOR PIPELINE CLAMPSfor INTERNAL ALIGNMENT AND WELD PURGING

Two stage clamping of pipesFeed clamp through one pipe and expand into the secondpipe end at low hydraulic pressure.

Abut second pipe and expand clamp further, so that bothpipes are rounded, aligned and clamped ready forwelding.

(1) Head UnitGood rounding ability is achieved by the use of multipleclamping segments.

Pipes with small bore differences are accurately aligned andfirmly clamped by the independently acting front and rearcone fingers.

Strong clamping forces eliminate tacking when closed buttwelding.

The clamp's internal purge gas system provides immediateprotection to the weld joint.

(2) Wheeled Support TubeAdjustable wheels maintain the clamp on centrelinethroughout its 10% working range.

(3) Hydraulic Power PackThis compact oil reservoir/pump unit fitted with pressuregauge, provides 700 bar hydraulic pressure (from an airsupply of 6-7 bar) to the cylinder within the clamp.

Optional electric power pack is available.

(4) Hydraulic HoseHigh specification hoses combine both strength and goodflexibility.

The flat faced push-in hose couplings ensure disconnectionwithout oil spillage.

Setting caliper simplifies theaccurate location of the head unitfor first stage clamping.

For use on 11/2 D bendsRemoval of the wheeled support tube enables theclamp to be passed around 1 1/2 D bends. *
