- Anticipating ASME NPT accreditation
Sheffield Forgemasters International Ltd, the British engineering group, reported recently it has retained a 20-year quality certification for civil nuclear castings and forgings. The Quality System Certificate was renewed once the group passed a rigorous conducted audit by the American Society of Mechanical Engineers (ASME) 3800 Code survey.
“This qualification recognizes our quality levels,” stated David Street, Sheffield Forgemasters’ group quality director. “Our role as a Tier One member of the Nuclear Advanced Manufacturing Research Centre (NAMRC), allows us to play a crucial part in establishing quality assurance requirements for businesses aiming to enter the UK civil nuclear supply chain.”
The ASME Code is a comprehensive series of directives for manufacturing parts and systems for civilian nuclear operation, and similar in scope to all other compliance requirements. SFIL noted this is important because its work with civilian nuclear power producers, engineers, and contractors around the world will be strengthened by the recertification. Specifically, it stated that its reputation as a supplier of heavy castings and forgings for nuclear-power projects will continue as a consequence of the achievement.
The manufacturing complex at Sheffield, England, includes electric furnace melting and casting for ingots, forging and foundry operations, as well as and large-dimension machining capabilities.
The group’s forging capabilities include a 10,000-mt press with a fully integrated, 300-m metric ton manipulator; a 4,000-mt ton press with an 80-metric ton rail-bound manipulator; and a 2,500-mt press with a 50-mt rail-bound manipulator, and 8-mt mobile manipulator.
SFIL is a longtime supplier of nuclear components, citingtransition cones, shell strakes and tubesheets as well as parts for pressurizers as some of the typical products. Rolls Royce Plc and Sheffield Forgemasters Engineering collaborated to develop components for the U.K. nuclear submarine program, and Sheffield Forgemasters is the principal supplier to Rolls of safety-critical components for the submarine program. “This work has culminated in the development of innovative forging techniques to enhance the mechanical properties of safety-critical nuclear components for submarine units by more complex shaping at the forging stage,” the group explained, and that technology is being transferred to the production of large civil nuclear components. It is being extended to involve hot extrusion processes, too, according to SFIL.
