Nuclear Connect article- Duct weld quality

Nuclear Connect article - Duct weld quality

Duct weld quality is key to performance assurance

When it comes to assuring the performance of commercial and industrial ventilation products, attention to detail for each element of the manufacturing process is critically important. This is true for the specification of ductwork across the broadest spectrum of applications – from standard air movement solutions in commercial construction projects to the installation of systems in high consequence locations, including nuclear, pharmaceutical and advanced manufacturing environments.

According to Mark Simpson, Quality Manager with leading ductwork manufacturer Hargreaves, buyers and specifiers should pay particular attention to the quality and consistency of a producer’s welding procedures, because this is a core factor in determining the overall standard of a manufacturer’s products.

“Welding lies at the heart of the ductwork fabrication process,” comments Mark. “Once a building is commissioned and operational, its owners and users must be able to take the performance of its air movement system for granted. And, while the design of the air management system, and the quality of the materials used will both impact on the efficacy of the solution, the integrity of the welds will also be a vital determinant in ensuring that the system will continue to perform properly across the lifetime of the installation.”

It’s for this reason that Hargreaves ensures that all its welding activities are performed to the highest quality standards.

“All our welders are qualified in accordance with UKAS approved BS EN 15614”, says Mark. “This is the benchmark welding procedure test that they must be able to achieve. Our welders are also qualified in accordance with UKAS approved BS EN 287 – the qualification test for fusion welders. The standards that our welders must achieve are witnessed, evaluated and tested by a UKAS accredited company, which means that our welders’ abilities match and surpass the most demanding levels of skill set down by the government’s sole accreditation body.”

Hargreaves’ commitment to UKAS-evaluated standards means that the company’s customers are assured of quality and consistency for its mild and stainless steel high integrity air movement products.

“While ease of installation, high performance materials, cost-effectiveness and aesthetic appeal are all important criteria in choosing air management solutions, ensuring that an application has quality built into the heart of the system’s fabrication should also be a vital consideration,” says Mark. “As a manufacturer with a strong heritage partnering with high-consequence industries, as well as an enviable track record in manufacturing for retail, commercial and leisure, our commitment to fabricating to UKAS welding standard is central to our production philosophy – and it’s a standard that all our customers can rely on, whatever the purpose of their next project.”

Hargreaves is one of the UK’s leading providers of air movement and ventilation ductwork solutions, delivering projects throughout the UK ranging from Nuclear and Industrial Processes, to Healthcare, Retail, Commercial and Leisure.

HARGREAVES WINS TOP NUCLEAR AWARD – Press Release

October 2013

HARGREAVES WINS TOP NUCLEAR AWARD – Press Release

Hargreaves, one the UK’s leading providers of air movement and ventilation ductwork solutions, has been awarded a prestigious certification in quality and fabrication standards by Sellafield Ltd.
Bury-based Hargreaves has now become only the third Sellafield supplier to receive the Quality and Fabrication Standards certification developed in collaboration with contractors in the industry.

The certification process was developed as part of Sellafield’s assurance activities to reduce the risks of encountering shortfalls in performance through the supply chain.
Managing Director of Hargreaves, Tim Hopkinson, acknowledged the achievement saying: “Hargreaves is proud to have been awarded this certification from Sellafield and to have demonstrated that we can meet the rigorous standards of one of the largest nuclear facilities in the world.

“We have a long history of supporting the site and, with this certification, we are now able to demonstrate to our supply chain partners that we are strongly positioned to deliver quality solutions to accept nuclear industry challenges going forward.”
The certification process involves the completion of a formal gap analysis against the organisation’s ISO 9001:2008 Quality Management Systems programme and any other specific Sellafield Technical or Quality requirements. The gap analysis then allows the Lead Auditor to develop a detailed check list to use at the supplier’s workplace.
Noting the significance of the certification, Sellafield Commercial Director, Keith Case, explained: “Sellafield needs contractors and suppliers who can perform to the highest standards, so we have developed this new certification standard to offer increased assurances around our supply chain’s capabilities.

“Achieving this certification is a mark of Hargreaves’ commitment to high quality performance and I would like to thank them for their continued support to our business.”
During a typical certification assessment, the Sellafield team will review numerous documents, conduct physical inspections at the supplier’s workplace, and assess their manufacturing capabilities, capacities, level of automation, technical and engineering competence and flexibility. Direct interviews with the senior management team will cover issues such as policies and procedures and roles and responsibilities. Throughout the entire process, the audit teams collect objective evidence to support the decision making process and to aid the preparation of the certification report.

Founded in 1872, Hargreaves is an established manufacturer, contractor and supplier of ductwork and ventilation products nationwide.
The company has a track record of delivering complex ductwork projects, and has worked extensively within the nuclear industry, and also the pharmaceuticals, rail including tunnels, retail, commercial and leisure sectors.
