About the Broadbent Manufacturing Division
Wide-ranging materials capability
The Division brings together impressive experience and expertise in working with a vast range of materials from traditional to the more exotic. We handle everything from mild steels through to 300 series, duplex and super duplex stainless steels, as well as nickel, Monel, Hastelloy and titanium, all of which can be fabricated and machined components.
Our 85,000ft2 (8,000m2) premises comprise three main manufacturing bays with 20 x 20ft (6 x 6m) access and lifting facilities up to 25 tonnes. Our precision services include:
- dynamic balancing
Fabrication and Welding
The Fabrication Department is well equipped with a large selection of plant to cope with the construction of medium to heavy centrifuges and other similar products. Our skilled engineers are qualified in ASME IX, NACE on SMAW, GTAW, SAW, GMAW and FCAW across a wide portfolio of materials including 2205, 2507, Zeron and Hastelloy.
Broadbent is a member of the Welding Institute who are specialists in all forms of welding, jointing and NDT for industrial applications.
With up to 25 tonnes’ overhead lifting capacity and flexible positioners, we have the optimum welding capability to achieve high-integrity welds. We also make extensive use of both internal and external NDT to confirm weld quality and to comply with our agreed quality plans and weld procedures.
