Rauvitherm Reward Scheme – REHAU Rauvitherm Connections

What is REHAU Connections?

REHAU Connections is a points-based loyalty scheme open to installer companies purchasing REHAU RAUVITHERM pipe.

How does the scheme work?

Every time your company purchases a length of REHAU RAUVITHERM pipe you earn Connect Points which can be redeemed in exchange for items on the REHAU ‘Redeem and Select Rewards’ page.

How do I earn Connect Points?

Connect Points are assigned every time a purchase is made and logged by your company online. A copy of the purchase invoice or order acknowledgement must then be sent to REHAU Connections for approval via the Freepost address, fax or email.While awaiting approval, the Connect Points will appear as ‘Pending’ on your ‘My Account’ page meaning that they have not yet been added to the account balance.

Once your invoice is approved the Connect Points will automatically be transferred to the account balance and can be redeemed.

How do I create an account?

To create an account all you need to do is go back to REHAU Connections homepage (www.rehauconnections.co.uk) and click ‘Register here’. From there you’ll be taken to a page where you can register/create an account.You only need to create an account once. Or Click on the Register button below.

How many Connect Points can I earn?

The number of Connect Points you can earn is dependent on the purchases made; there is no limit applied whilst the scheme is running.

How do I redeem my Connect Points?

To redeem Connect Points you need to go to the ‘Redeem Points & Select Rewards’ page (This will appear as a tab at the top of the page, once logged in). Here you will see a scrolling list of all the items currently available for you to redeem your Connnect Points against and the number of points required per item. Items that appear ‘greyed out’ in the list are items that are either not currently available or your Connect Points balance is below the points value of the item listed.

Steel Pipe

Overview

The pipe system
isoplus’s pre-insulated pipe systems are bonded systems. The pipes consist of a steel carrier pipe and a HDPE jacket pipe, which are cast into a fixed sandwich structure with polyurethane insulation.

Steel pipe
Standard quality, longitudinal weld or spiral weld, P235TR1, P235TR2 or P235GH. Technical terms of delivery as per EN253.
Weld factor V = 1.0
Test certificate as per EN 10 204 – 3.1.
Bevelled ends as per ISO 6761.

Insulation
The insulation is polyurethane foam with cyclopentane used as blowing agent, for optimum insulation values.
Compressive strength: 0.3 N/mm2
Continuous operating temperature, single pipe 143°C
Continuous operating temperature, double pipe 130°C
By special order, isoplus can supply preinsulated pipes that can withstand a continuous operating temperature of 161°C.

Jacket pipe
The jacket pipe is made of polyethylene that is resistant to impact and fracture.
Material: Bimodal – HDPE
Density: over 940 kg/m3
Melt flow index: 0.2-0.7g/10 min., 5 kg as per ISO 1133
Elongation at fracture: min. 350%
Internal corona treatment: to optimise bonding characteristics.

The pre-insulated pipe
The pre-insulated pipe at least meets the requirements in DS/EN 253. The axial shear strength of the pre-insulated pipe, between the steel pipe, PUR and casing pipe, is at
least 0.12 N/mm2.
Exposed end of steel pipe: 220 mm
Standard lengths: 6, 12 and 16 m
Corrosion protection is applied to exposed ends on delivery.

Alarm system
isoplus pipes and components can be supplied with two integrated copper wires (1.5 mm2) for electronic monitoring.

Fittings
All fittings are produced in accordance with the requirements in DS/EN 448 and DS/EN 488.

Diffusion barrier
isoplus can produce pipes with jacket pipe dimensions ≤ ø355 mm as energy-saving, continuously produced pipes with a diffusion barrier inserted between the jacket pipe and the polyurethane foam.

For pipes with jacket pipes in dimension >ø355 mm, the jacket pipe functions as a diffusion barrier due to its thickness.

The diffusion barrier secures isoplus pre-insulated pipes against ageing, and the heat loss is therefore constant throughout the pipe’s technical service life.

Series 1 pipes are normally supplied as traditionally produced pipes without an inserted diffusion barrier. However, dimensions with jacket pipes ≤ ø355 mm can be supplied as continuously produced as a special delivery
