    World-Class Support

    At CPV we pride ourselves by the way in which we support our customers – from the moment that they first contact us through to their long-term operation and maintenance of a pre-insulated pipe network. As manufacturer, it’s important to us to ensure that our systems deliver exceptional performance throughout their working life. Therefore, we have established an array of world-class support services that help our clients every step of the way.

    Design and Stress Analysis

    designing district heating systems 400x167There are many factors that will affect the long-term integrity of a pre-insulated pipe system. Correctly identifying and dealing with the potential for thermal expansion of the pipe system is a critical element of the design process and we employ state-of-the-art sisKMR specialist stress analysis software. This package allows us to configure the pipe routes to keep the thermal expansion within safe limits and conform to the requirements of the EN 13941 standard for Design and installation of pre-insulated bonded pipe systems for district heating. Please click this link to find out more about our advanced stress analysis service for district heating pipe networks.

    Training

    Training installers, supervisors and maintenance operatives, our brand new training centre allows for not only the theory, but hands-on practical experience in the correct method for installing the Hiline pipe systems. In addition to this, we also offer training courses in the design, installation, commissioning and maintenance of electronic surveillance systems – including the use of our own buried pipe network, on which we can simulate moisture faults as part of the practical training.

    Tool sales and hire

    We offer both the sale and short-term hire of all the specialist tools required to install the Hiline pipe system.

    Trace and Maintained Heating Systems Support

    In temperature-critical, special applications that require round-the-clock maintenance of a specific media temperature, we can supply the Hiline pipe system with Trace or Maintained Heating systems.

    On-site support services

    Whether it’s on-site training, site supervision or specialist advice, support and maintenance – our engineers are at hand to provide customer support as and when required.

    The True Cost of Insulation

    The effects of using a more efficient insulation don’t appear to be much at face value, but factor in a minimum 30-year life-cycle cost of operating the system and the savings – both financial and environmental – mount up significantly. The Hiline range of pre-insulated pipe systems are available with increased levels of insulation thickness – which for a relatively small additional investment at the time of installation – will yield significant savings during the lifetime of the system.

    To illustrate this point, take an example scenario in which a 5,000-metre long network (flow and return) consisting of DN150mm steel pre-insulated pipes circulating hot water at a flow temperature of 100°C. If fuelled by a natural-gas-fired boiler, constantly operating all-year-round, the system with standard insulation – over its nominal 30-year life – will lose heat to the equivalent of around £3.65 million’s-worth of gas(*) and emit 15,250 tonnes of CO2.

    By making a small additional investment – equivalent to around 10 percent of the material cost at the time of installation – in order to upgrade the Hiline pipe system’s insulation thickness to Series Two, the cost of the heat lost would be reduced by some £1.2million – also saving 5,091 tonnes of CO2 from being emitted. The graph shown demonstrate the effects that this can have.
