ULTRAGRIP FLANGE ADAPTORS PN10 DN900
Installation Instructions
1. Check that pipe material and size are suitable for the UltraGrip Flange Adaptor. For PE always use a support liner.
(See pages 8-9)
2. Examine pipe ends and ensure that pipe surfaces are 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 sit either on to
the bare pipe surface or on a thin paint film.
3. Hazard Warning: Lifting lugs, where provided, are designed/tested for lifting only the product to which
they are attached. Failure to follow these instructions could result in serious personal injury or death,
or property damage.
Ensure that you are trained, competent and familiar with the lifting appliance and accessories to be used.
Ensure that the correct equipment is used and is marked with its WLL (Working Load Limit) or tables are
available to determine the WLL. Ensure that you visually inspect the lifting gear and accessories before
proceeding with the lift, discarding defective equipment. Ensure work is within the WLL for the equipment.
Do not use equipment that is faulty, or operate it beyond the WLL. It must be examined by a competent
inspection engineer and re-certificated. Only undertake slinging and banksman's duties if you are competent
and have been trained. This must be provided by a recognised training provider. Never walk underneath
or slew a load over a person.
4. All UltraGrip Flange Adaptors incorporate hygiene protective caps (which consist of bio-degradable tie-wraps
and bio-degradable water resistant cardboard) to prevent contamination. This must be removed prior to fitment
(Fig 1). Gasket spacer block (Fig 1) should NOT be removed at this point.
5. To ensure correct installation, mark the minimum and maximum pipe insertion depths obtained from Table 5
around the full circumference of both pipe ends as shown in Fig.2.
6. Slide the UltraGrip Flange Adaptor onto pipe end. Align the pipe and UltraGrip Flange Adaptor with mating flange,
fit flange connecting gasket (Viking Johnson recommend using an IBC gasket for optimum sealing) and flange
connecting bolts. Ensure pipe is inserted to a depth between X(min) and M(max) as shown in Fig 3 using depths
obtained from Table 5. – adjust if necessary. Tighten flange connecting bolts using standard procedures. If the
mechanical fitting is being installed on plain ended pipe. The end of the product should sit between the minimum
and maximum insertion depth X(min) and M(max) (Refer table 5).
7. All UltraGrip flange adaptors incorporate gasket spacer blocks (Fig.1) which prevent the end rings from collapsing
during transportation. These must be removed prior to fitment at this stage.
8. Tighten diametrically opposed nuts of the axial fasteners as per Fig 4, 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 torque (Ref Table 5). On completion, there should be an even radial gap between pipe and end ring
of the fitting, with all of the M(max) line being visible and none of the X(min) line visible.
9. Decide now what type of connection is required: GRIPPING or NON-GRIPPING:-
a. GRIPPING - When used as a gripping type, tighten diametrically opposed bolts of the radial fasteners as
per Fig 4, giving each bolt one or two turns at a time to engage the grippers evenly. All bolts are required to be
tightened up as many times as necessary to achieve the required torque (Ref Table 5).
b. NON-GRIPPING - When used as a non-gripping type, the radial fasteners must not be torqued. When installed
as a flexible (non-gripping) product UltraGrip does not prevent pipe pull-out and adequate external restrain has
to be provided.
