CPV-Zurn system for new cardiac expansion at Southampton Hospital

Three complete CPV-Zurn chemical waste system stacks have been installed as part of a £25m cardiac revascularisation expansion of the North block of Southampton Hospital.

In the project design, provision had to be made for a proposed future installation of sterilising units on the roof. The sterilising units would provide demineralised water at very high temperatures, requiring an extremely resistant system of pipes. Additionally there was a requirement for the safe drainage of waste from a chemical laboratory being built in the new extension.

George Morgan, a freelance consultant working with project consultants Henderson Green, explained: “The high temperature demineralised water would be very corrosive to traditional waste pipe materials. This led to the CPV-Zurn system being chosen because of its outstanding resistance and robust design.”

CPV-Zurn pipe and fittings are made to very high quality control standards. In the UK the manufacturing facility is ISO 9001 certified. Pipe and fittings are made from block copolymer polypropylene, the material of choice for chemical drainage equipment. Polypropylene can withstand a wide range of temperatures (from -20°C to 110°C) and is resistant to most organic and mineral acids, alkalis, alcohols and salt solutions. The system complies with ASTM 1412, the only internationally recognised standard specifically for chemical and corrosive drainage.

Henderson Green were initially asked to deliver a ‘shell and core’ design - before moving to a full design. This is essentially the building structure with basic services installed – common practice in the construction of offices and shop units but not so for hospitals. The project includes treatment wards, MRI, support facilities, a new Heartbeat Institute, medical admissions ward and associated engineering infrastructure, due for completion in Spring 2007.

CPV Ltd is a specialist thermoplastics manufacturer, founded in 1949, with a wide range of industrial and building related products. These include chemical resistant pressure pipes, pre-insulated pipes, fittings and valves and custom fabricated bulk tanks and vessels. All are supported by CPV’s technical back-up and training.

CPV-Bulk: CPV's Largest Tank!

Complete Satisfaction from CPV's Largest Tank

Any round-up of developments in bulk storage should include telemetry and automated process technology. As the complexity of these systems increases, the ability to pre-fabricate a completed storage solution is increasingly important. The economic benefits of pre-fabrication lie in saving assembly, installation and commissioning time and costs on site.

Tank designers at CPV believe that strong communications are vital in this respect, as highlighted by the company’s latest bulk storage project. As preferred suppliers of chemical storage tanks to Johnson Diversey, CPV consulted at an early stage, allowing collaboration on design, delivery and commissioning of a 20,000-litre polypropylene tank and two 7,000-litre tanks, fully fitted to specification. As the two companies worked closely, there were no unwelcome surprises when the tanks arrived on site, leaving JohnsonDiversey able to complete the project within deadline.

The full scope of the project called on JohnsonDiversey to supply a full hygiene package to one of Europe’s largest fruit juice manufacturers, at a new site in the South West of England. CPV’s 20,000-litre tank was the largest the company has yet manufactured in polypropylene. Actually constructed as a tank within a tank, it holds caustic detergent for dosing to a cleaning-in-place (CIP) system for product pipelines, vessels, and filling machines.

The outer tank forms an integral bund around the inner and is equipped with a leak detection alarm system complete with pipework for liquid removal. All pipe connections are top mounted minimising the chance of damaged to twin wall design. Both inner and outer tanks are fully capped for full weather-proofing. Manufactured from Black Leather grain Polypropylene for use outdoors. Designed and built in accordance with BS EN 12573 (applying to welded thermoplastic storage tanks for corrosive liquids) backed up by in-house quality procedures in accordance with ISO 9002.

CPV supplied the tanks complete with control panels. All three tanks are fitted with telemetry systems to allow remote monitoring of levels by the chemicals supplier, thereby optimising re-ordering and delivery procedures.

CPV Ltd, founded in 1949, specialises in manufacturing a wide range of industrial and building related thermoplastic products. These include an above-ground chemical waste system, chemical resistant pressure pipes, pre-insulated pipes, fittings and valves and custom fabricated bulk tanks and vessels. All are supported by CPV’s technical back-up and training.

CPV-Zurn: Blue Is The Colour For Chemical Waste Drainage

An installation at the UK’s leading nanotechnology research centre last month showed just how versatile the all-blue, CPV-Zurn chemical waste drainage system can be in connecting to existing pipework.

The Centre for Integrated Photonics (CIP), at Martlesham, is a research and development organisation specialising in integration technologies for microsystems and nanotechnology. An expansion of the existing facilities required the addition of new tanks for waste acid neutralisation, with isolation valves and drainage pipes.

As this installation had to integrate with the Centre’s current waste systems, the chemical drainage system was carefully selected for its compatibility, or ‘connectivity’, in addition to proven performance.

The choice of CPV-Zurn ensured that the CIP engineers and installation contractor, Bower Fuller (Ipswich) experienced both trouble-free pipework and the full technical support of the CPV factory. This included factory pre-assembly of ball valves with CPV-Zurn connectors, ready for immediate use.

Mark Myatt, Contracts Manager for Bower Fuller: “The main thing from an installer’s viewpoint is that CPV provided a quick service and the pipe and fittings were there when needed. The unique blue colour identifies the new pipe as a specialised chemical-resistant product. We would definitely be happy to use the system in future”

The new pipes connected to existing CPV Natural polypropylene and Vulcathene pipes without a hitch. In this case, the CPV-Zurn system was joined mechanically although each individual fitting is designed to give the designer, or installer, the choice of mechanical or electrofusion coupling.

Produced in blue block copolymer polypropylene, the leading material in chemical drainage equipment, the system uses high modulus pipe and out-performs competitive products in strength and rigidity. It complies with ASTM-F1412, the only internationally-recognised standard specifically for chemical and corrosive drainage and complements CPV’s above-and-below-ground waste drainage catalogue, which includes floor gullies, linear drains, dilution pots, interceptor tanks, underground pipes to EN 1852-1 and access chambers.

CPV-Zurn: Chemical Drainage in Agricultural Labs

Laboratory waste drainage facilities, recently installed at the Harper Adams University College, Shropshire, use the CPV-Zurn system to handle liquid chemical waste safely.

The new molecular diagnostics laboratories were opened by HRH The Princess Royal, following a £0.5 million conversion of one of the university college’s buildings. CPV-Zurn was a clear choice, having successfully equipped hundreds of educational laboratories and industrial applications.

Mechanical and electrical design was by Burgess Design Associates. Des Greensmith explains: “This system appealed because it offers significantly higher strength, rigidity and a number of design advantages over its competitors, without adding cost. The distinctive blue colour also clearly differentiates it as chemical waste pipework, whereas other systems can be mistaken for wastewater drains.”

All pipe jointing was done mechanically. A key benefit of CPV-Zurn is that each individual pipe fitting is equipped to allow a choice of electrofusion, or mechanical connection. Although the Harper Adams project involved new laboratories, the drainage system is versatile enough for upgrades and repairs, connecting to existing pipework made by other major manufacturers.

Made in tough, block copolymer polypropylene, the leading material in chemical drainage equipment, the system complies with ASTM 1412. This is the only internationally-recognised standard specifically for chemical and corrosive drainage.

Estates and Facilities Manager at the university college, Paul Moran, comments: “Laboratory drainage is something I don’t want to be worrying about after installation. That is all the more reason to entrust chemical waste drainage and containment to a proven, reliable system like this.”

The new laboratories at Harper Adams University are in the Foulkes-Crowther building, built in 1968. Money from the Higher Education Funding Council for England enabled its conversion from a library and teaching accommodation. In addition to the laboratories, the building now provides 11 new teaching rooms, three computer-based teaching rooms and office space.

CPV-Zurn: Installs Faster, Performs Better

The CPV-Zurn chemical waste drainage system, launched in the UK by CPV Ltd of Romsey, incorporates a novel concept in drainage pipework – the electrofusion/mechanical fitting. Giving jointing flexibility and compatibility with other systems, the combination fitting is one of many features designed in response to market demand for faster, easier installation of high quality chemical drainage pipes.

The fitting eliminates the need for external clamping, which is a normal requirement when fusion-jointing plastic pipes. Installation is much quicker as a result. Alternatively, each connection can be made mechanically, as a simple pull-out resistant, grooved joint.

Produced in blue block copolymer polypropylene, the leading material in chemical drainage equipment, the system uses high modulus pipe and out-performs competitive products in strength and rigidity. It complies with ASTM-F1412, the only internationally-recognised standard specifically for chemical and corrosive drainage.
Benefits for the design engineer and building owner start with proven reliability and performance, in uses ranging from educational and medical laboratories to water treatment and metal etching facilities. The system also connects successfully with existing drainage installations and forms part of CPV’s complete above-and-below-ground chemical and corrosive waste drainage catalogue. This includes floor gullies, linear drains, dilution pots, interceptor tanks, underground pipes to EN 1852-1 and access chambers.

For the distributor the key benefit is the simplicity of stocking just one fitting for both fusion and mechanical connections. Combination fittings also assist the installer, with fewer different parts required to complete a project. Pipework runs are built up using the mechanical nut, thereby avoiding clamps during electrofusion, and fusion terminals swivel for convenient connections.

Sales Manager, Mark Whettall, explains why the time is right to launch the product: “CPV has over 30 years’ experience in manufacturing and installing laboratory chemical waste systems. We have looked carefully at what the UK and Europe needs and can now offer the market a complete and fully compatible system that will perform at least as well as its rivals, while being far easier to stock and install.”

The CPV-Zurn system has a high quality fusion unit with a range of features to reduce operator error and save installation time. These include automatic recognition of connected joint sizes and quantities, enabling simultaneous fusion of different joints. Flexible, rotating fusion connections mean that they are never in an awkward location when setting up for fusion.

Note to editors

The CPV-Zurn system has been developed by CPV for the European market, based on the Zurn system. Zurn has an outstanding record of reliability in the USA, where it has become one of the top four best-selling brands in chemical drainage. For applications where fire safety is critical, CPV has a fire retardant polypropylene system and a self-extinguishing PVDF system, which is useful in high temperature, acidic waste drainage.
