NOTES
These instructions relate to the UltraGrip range of Flange Adaptors
for use on the pipe materials noted in the table.
UltraGrip is supplied fully assembled for use as an end restraint
(gripping) product and should not be dismantled prior to installation,
unless it is to be used as a flexible (non gripping) product in which
case the only components to be removed are the red grippers.
* Site test pressure = 1.5 times working pressure
Thick pipe coatings and protective wrappings must always
be removed
1. Check that pipe material and size are suitable for the UltraGrip Flange Adaptor.
For PE always use a support liner, for PVC use a support liner when required (Ref Table 3).
2. Examine pipe end and ensure that pipe surface is clean and free from score marks, scale,
rust or any loose debris or other surface defect that may affect fitting performance.
Weld beads must be ground flush, maintaining correct surface profile. Thick pipe coatings
or wrappings must always be removed. UltraGrip must seat either on to the bare pipe
surface or on a thin paint film.
3. Safe Handling Measures: When manoeuvring the product from packaging to pipe surface,
please ensure that correct manual handling procedures are adopted. When mechanical lifting
aids are required, ensure that the use of safe working practices is adopted and all lifting
equipment is rated for the loads.
4. All UltraGrip couplings incorporate hygiene protective caps to prevent contamination.
This must be removed prior to fitment (Fig 1).
5. Align pipe to be laid with pipe already in position, taking care that pipe ends are concentric,
adjusting support or trench bed as necessary. The enhanced gasket technology employed does
not require the use of any lubricant; therefore ensure no lubricant is applied.
Decide now what type of connection is required: GRIPPING or NON-GRIPPING:-
GRIPPING - When used as a gripping type (only for buried applications), the fitting must
be installed as supplied, with the gripper strips in position (Fig.2a). Check if all grippers are
inserted correctly.
NON-GRIPPING - When used as a non-gripping type, the gripper strips have to be removed.
Simply slide out the gripper strips (Fig.2b). When installed as a flexible (non-gripping) product
UltraGrip does not prevent pipe pull-out and adequate external restrain has to be provided.
6. Slide the UltraGrip Flange Adaptor onto pipe end. Align the pipe and UltraGrip Flange Adaptor
with mating flange, fit flange connecting gasket (Helden recommend using an IBC gasket for
optimum sealing) and flange connecting bolts. Ensure pipe is inserted to a depth between
T(min) and T(max) as shown in Fig.4 – adjust if necessary. Tighten flange connecting bolts
using standard procedures.
7. Before tightening the UltraGrip bolts ensure that each bolt head is captivated securely in the
slot hole. Tighten diametrically opposed fasteners, giving each nut one or two turns at a time
to draw up the end ring evenly. All nuts are required to be tightened up as many times as
necessary to achieve the required bolt torque (Ref Table 3). On completion, there should be
an even radial gap between pipe and end ring of the fitting, with all of the T(max) line being
visible and none of the T(min) line visible.

Above ground exposed pipework is subject to both
loads from the internal pressure and those from
temperature changes / thermal expansion, which can be
substantially higher than those from internal pressure
and cannot always be safely determined. For this reason
it is recommended that the use of UltraGrip be restricted
to buried pipelines, valve chambers and above ground
indoor applications not exposed to direct sunlight or
excessive temperature changes (e.g. pump houses).
