The Remote EasiClamp product is only available with an EPDM gasket for use on potable / dirty water applications and can not be used on any gas applications or where there is the possibility of oil in the dirty water.

The Remote EasiClamp product range has been designed for use on cold potable water applications and as such will function up to a temperature of 40Deg C.

The working pressure of the Remote EasiClamp range is 16 bar, with a site test pressure of 24 bar.

The body to the products is 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.

The unique patented hinge design incorporated in the clamp means that there are no additional pins required, thus preventing any bimetallic corrosion from different metals.

The bolts / nuts are coated with Sheraplex to WIS 4-52-03.

During the development of the new range of UltraGrip we have reviewed the insertion depths in the new product. These are now only a function of diameter and no longer depend on if a support liner is used – see table below:-

Pipework installed above ground can be subjected to large changes in temperature (maximum in summer to minimum in winter) and this change in temperature introduces forces into the pipeline that have to be accommodated by any connection. These forces can be substantially larger than the end load forces due to the internal pressure of the pipeline and UltraGrip has not been designed to accommodate these additional forces. Buried pipework is not subjected to large changes in temperature, thus limiting the forces that have to be accommodated by the coupling to only those due to internal pressure.

Since it is not possible to predict safely the additional loads due to thermal expansion and contraction the use of UltraGrip in the gripping mode from a health and safety perspective is limited to buried applications only.

Direktiva o tlakovoj opremi primjenjuje se na projektiranje, proizvodnju i ocjenu sukladnosti tlakovih uređaja i sklopova tlakovih uređaja s maksimalno dopuštenim tlakom većim od 0,5 bar.

UltraGrip products are not defined as pressure equipment or pressure accessories but are defined as component parts for pressure equipment for which the PED specifies no specific assessment procedure. Their suitability where applicable will be checked on the occasion of conformity assessment of the complete pressure equipment or assembly.

Npr. sklop kompresora može se definirati kao tlačna oprema sastavljena od pojedinačnih dijelova, uključujući cijevi, prirubnice, spojnice i ventile itd. Cijevi, prirubnice i spojnice neće zahtijevati pojedinačnu procjenu prema PED-u niti CE označavanje, ali kada se sastave u "cjelinu", sklop kompresora će zahtijevati procjenu u toj završnoj fazi. To će biti odgovornost proizvođača ili sastavljača sklopa kompresora. Ventili se, međutim, prema PED-u smatraju tlakovim priborom i zahtijevaju zasebnu pojedinačnu procjenu i razmatranje za CE označavanje. To će biti odgovornost proizvođača ventila.

The gaskets in the UltraGrip products now incorporate features from the waffle design that has been used in the EasiRange of repair products. The waffle design now not only provides a series of high pressure sealing points that run circumferentially round the pipe but also one that run longitudinally under the gasket.

The manufacturing tolerances for PE pipe mean its bore will always vary in diameter. PE pipes are not “rigid” and when the pipe is subjected to an external load (from the gripper / gasket) it will over time react and deform away, so for this reason we have to use a support liner that after installation is in contact with the bore of the pipe to prevent it from over time collapsing and leaking. There are two types of support liners:-

The carrier and gripper sub-assembly mechanism in UltraGrip is only designed to collapse down onto the pipe surface to mobilise the seal and friction grip and not designed to also collapse the PE pipe onto the support liner, hence the need to use “close fit” liners.

UltraGrip can be used on PE pipe so long as a close fit support liner is used.

PE pipes are not “rigid” and when the pipe is subjected to an external load (from the gripper / gasket) it will over time react and deform away, so for this reason we have to use a support liner that after installation is in contact with the bore of the pipe to prevent it from over time collapsing and leaking. Another characteristic of this pipe material is that its length reacts to both thermal and pressure changes and these changes can be large – i.e. it expands / contracts and if not fully restrained in a coupling.

The UltraGrip product range can be used on the following pipe materials, which depends on if it is being used in the gripping / restrained or non-gripping / flexible mode as follows:-

No. The high external load applied by the UltraGrip seal and gripper will delaminate GRP pipe.
