Stainless Steel and Copper pipes are too thin to be able to use UltraGrip. ABS pipe can be used with a support liner.
Yes
No. All the couplings with Cup Square Heads are reversible. These are on all Couplings and Pecatadaptors from DN100 and larger and on all Reducing Couplings. UltraGrip End Caps have Pan Head bolts which are also reversible. UltraGrip Flange Adaptors do not have reversible bolts.
The Grippers can be replaced alone if this is all that is required.
The Grippers should be changed after each use of the UltraGrip End Cap. The complete sub-assembly should be changed if the Carriers are out of shape.
Yes
PVC pipe to German Standard DIN8062 Class 4 does not require a support liner. All other PVC pipe is considered ‘Thin Walled’ and will require a support liner.
AC pipe is manufactured from asbestos fibres and cement slurry, with the encapsulated asbestos fibres acting as a reinforcing material to form an intrinsic part of the cement matrix. The main issues preventing the use of UltraGrip on AC pipe are:-
- It is not possible to confirm the structural strength of the AC pipe in the field
- The grippers will impose a high load on the AC pipe and potentially crack the pipe
- It is not possible to get a reliable friction gripping action between the UltraGrip and the fibre cement matrix material used to manufacture the pipe, which may be deteriorating.
The UltraGrip product range is suitable for use on gas applications, so long as the working pressure of the system is 5 bar or less and the products are fitted with Nitrile gaskets.
The UltraGrip product range has been designed for use on cold potable water applications and as such will function up to a temperature of 30 Deg C.
The working pressure for UltraGrip NG is as follows:-
Water Applications:- DN40 to DN300 = 16 bar / DN350 & DN400 = 10 bar
Gas Applications:- DN40 to DN400 = 5 bar
All products have a field test pressure rating of 1.5 times the rated working pressure.
All cast components in UltraGrip products (sleeve, end ring, adaptor bodies etc) are fully coated with Black Rilsan Nylon 11, a thermoplastic polyamide produced from a renewable raw material of plant origin (Castor Oil) that meets WIS 4-52-01 part 1 and EN 10310. Rilsan has excellent resistance to impact, abrasion, weathering, many chemicals and with good thermal stability and flexibility to accommodate rough site handling.
As standard the bolts / nuts are supplied in stainless steel coated with a dry film lubricant to prevent galling during tightening. The nuts are Dacromet coated. UltraGrip End Caps are available with steel bolts & nuts coated with green Sheraplex to WIS 4-52-03.
