An Introduction to CPV

It’s hard to believe that the best part of seven decades has passed since our company was founded by my father back in 1949. It was the year that saw the maiden flight of the de Havilland Comet - the world's first passenger jet, BBC television finally started to be broadcast outside London and Britain signed the North Atlantic Treaty - creating NATO.

The world has changed immeasurably in the years that have ensued and the Chemical Pipe and Vessel Company, as it was known back in the early days, has itself experienced its fair share of change. However, some things have remained the same, namely, our guiding principles and the ethos that have helped CPV to become a world-class manufacturer of engineering pipework solutions for a wide array of applications, including corrosion-resistant pipe solutions and pre-insulated pipe systems for district heating applications.


CPV was a pioneer in the development of thermoplastic pipe systems and, to this day, we are still committed to driving forward innovation in products, services and manufacturing techniques. This not only improves the way in which our products perform, but it often lowers our clients’ capital and operational expenditure.

A friendly, family-run concern

Although we have steadily grown over the years to become an international group of companies, we have made a determined effort to retain our closely-held values as a friendly, family-run business. This filters through every aspect of the CPV Group, to the mutual benefit of our clients, employees, suppliers and associates. The markets in which we operate remain dynamic and, as environmental concerns grow ever-stronger, the demand for our state-of-the-art pipe systems continues to increase.

Thank you for taking the time to read this introduction, the remainder of this website will provide you with a host of information on our company and just how it can assist you with your projects and applications.

A World-Class Company

We operate in a wide array of sectors, with products satisfying many applications, most of which concern engineering pipe solutions for aggressive, corrosive, hot, chilled and potable liquids.

Our state-of-the-art production facility - based at the site of our headquarters near Romsey in Hampshire - is backed by a comprehensive selection of research, design, engineering, testing, quality, training and support services; ensuring the perfect marriage between our products and the applications they serve.

Product Solutions

Since our inception in 1949, we have regularly led the way in the research and development of pipe systems, tanks and vessels. Our current range encompasses:

  •  Pre-insulated Pipe Systems
  •  Chemical and Hazardous Drainage Systems
  •  Pressure Pipe Systems
  •  Custom Extrusions
  •  Custom Thermoplastic Fabrications

Design and Engineering Support

Our team of engineers offers a full design service for all of our systems.
From 3D product design, stress analysis and engineering, through to training, on-site testing and installation support - our clients can ensure the very best solution to their application.

Quality Assurance

With the objective of providing total customer satisfaction, CPV maintains an effective and efficient total quality management system which complies with BS EN ISO 9001. This system is continually reviewed for effectiveness and continual improvement – feedback from which is helping shape company objectives.

The Environment

At CPV, we strive to minimise our organisation’s impact on the natural environment. All of our waste materials are reprocessed and reused as second-grade raw materials in the manufacture of plastic products. In addition to this, we have been carefully managing the 85-acre site that accommodates our production facility and headquarters – having recently planted 20 acres of mixed woodland to encourage wildlife. It is also our aim to generate our on-site energy requirements from sustainable sources in the coming years – further reducing our carbon emissions.
