Hargreaves has launched a high purity pipework range.

The core product range consists of high purity stainless steel pipe, and is also available in   Polyvinylidene Fluoride (PVDF) and copper. It is manufactured in a class 100 (IOS 4/5) cleanroom facility at Newton Aycliffe near Darlington to strict quality assurance standards, incorporating separate access and exits for PVDF, copper and stainless steel, dedicated areas for preparation and welding and storage for completed spools within the clean room.

Hargreaves also offer a range of additional components including isolation valves, instrumentation, sight glasses, safety valves and filters.

Welding of the pipework will be carried out in accordance with ASME BPE 2002 and B31.3 standards. Orbital welders at the facility operate in ranges from ¼ inch to 6 inches for stainless steel pipe, and 20mm to 315mm for PVDF.

According to Hargreaves, the launch of the product range is a logical extension to their existing high integrity ventilation solutions portfolio.

Tim Hopkinson, Managing Director of Hargreaves commented: “The Hargreaves name is synonymous with ventilation, and we have earned a reputation for delivering high quality air movement and ventilation solutions in the most demanding conditions.

“In particular we have extensive experience of working in carefully controlled environments where exceptional air purity is required, such as the nuclear sector and the pharmaceuticals industry. The addition of high purity pipework will enable us to broaden our offer to existing clients and prospects in these sectors, and in other industries where the same exceptional quality and purity is paramount.”

Hargreaves is one of the UK's leading providers of high integrity air movement and ventilation solutions, winning numerous awards for the quality of its work in this industry. Founded in 1872 in Bury, Lancashire, they are an established manufacturer, contractor and supplier of ductwork and ventilation products nationwide.
