1. Installation


The pipe ends should be cut square and all sharp edges and burrs must be removed.


The pipe surface must be clean and smooth with no loose material in the region of the

sealing lips.


There must be no dents in the pipe ends must be within the limits specified for the coupling.


Mark half the width of the pipe coupling on both pipe ends as a fittin guide. This will enable the

coupling to be centred over the pipe ends when fitted.


Check that the coupling is of the right type and that a vacuum insert is fitted if required.


Remove the plastic packaging from the coupling.


Do not drop the pipe coupling.


Move one pipe end out of the way and slide the coupling over one pipe end. Repositin

the other pipe and slied the coupling over the joint into the correct position as shown

by the fitting marks alredy drawn on the pipes.


Tighten clamping bolts partially until the coupling is "nipped up" against the pipe. Do not

rotate the coupling on the pipe once the coupling is engaged.


Tighten clamping bolts evenly with a torque wrench to the final prescribed torque on the

final prescribed torque on the coupling label. Ensure that both bolts have reached torque

by moving from one to the other until both click off without further rotation.


Over- tightening is not recommendad and there is no need to re-tightening the bolts once

set as this will impede the "seating" of the gasket.


If in doubt always loosen the coupling, re-align and start again!





2. Removal


Ensure that there is no pressure in the pipes at the joint to be removed.


Drain the pipes at the joint as far as is practicable.


Protect yourself against spilling liquid.


Protect any surrounding equipment from spiied liquid.


Make sure the pipe coupling is not supporting the pipe ends.


Loosen locking bolts alternately but do not remove completely.


Do not rotate the pipe coupling on pipe as long as anchoring teeth are engaged (axilock only).


Loosen anchoring teeth engagement, if necessary, by gently rocking or tapping the loosened

coupling up and down the pipe (Axilock only).


Slide the coupling off the pipe.


Clean coupling and pipes ends and check the condition of the gasket before re-use.

5. Electrical Conductivity

figure 1/3


In Teekay pipe couplings electrical conductivity is conveyed through the coupling casing by the

anchor rings. In Teekay Axiflex pipe couplings stainless steel continuity strips are fitted to prevent

the build up of static electricity. These should be specifically reqested at time of order.




6. Shock, vibration, water hammer

figure 1/4


Due to the design of the gasket, Teekay couplings dampen sound, vibration and water hammer.

Shock levels to military requirements can also be accommended. In the case of Teekay Axiflex

couplings for applications where excessive vibration might occur, it is recommended that the

couplings are supplied with central registers to locate the pipe coupling in position.


6. Central Register

For above ground applications where there is a possibility that the coupling may move along

the pipe due to excessive vibration, expansion and contraction etc. the Teekay Axiflex Pipe

coupling can be supplied with a central register. The cebtral register is a circumferential ridge

integral to the gasket and serves to locate the coupling on the pipeline, thereby preventing its

movement. ( This should be specifically requested at time of order).
