ASME Certification

The new ASME III certification positions the Manoir Pîtres plant as the only French foundry certified for all possible construction codes in force in the nuclear industry! Following the RCCM and HAF 604 certifications, the organization and the quality system of Manoir Pitres’ Plant has been successfully awarded ASME certification (American Society of Mechanical Engineers) Section III certification – Nuclear (Material Organization). This certification defines the rules for equipment construction & inspection under pressure in nuclear plant worldwide. This knowhow makes…

Vertical Spinning

In the continuity of improvement of centrifugally cast parts, Manoir has extended its fabrication by installing vertical spinning equipment which is a complement to the horizontal spinning equipment used for tubes. The process consists in having the mold spinning around a vertical axis, while submitting the cast metal to varying acceleration according to their dimension or their shape. The advantages of this process are numerous: the pieces are perfectly sound and can meet the strictest radiographic test requirements, we obtain a…

The TOS® equipment, a machining center for valves and nuclear parts

In 2012, in order to accompany its customers, Manoir Pîtres decided to deliver some castings not only rough machined, but delivered at the final machining stage. This allows our clients to install directly the equipment without additional machining steps. Thus, assembly time is reduced and constraints related to the addition of others subcontractors disappear. The acquisition of the TOS® machining center gives to Manoir this capacity. The maximum weight capacity of the machining center is 20 tons, it is…

The fast line, Manoir shortens the production lead time of static castings

After few decades of operation Manoir Pîtres has decided to upgrade its static casting production process with a dedicated layout. After solidification, and before machining, a sequence of operations is carried out on static castings. These operations consist of: – Cutting the gating system (vents, risers…), – Grinding to shape, – NDT (Non-Destructive Testing): visual examination, dye penetrant testing, magnetic particle testing, and – Shot Blasting In the past, these various operations were carried out in particular workshop units, requesting many handling and then creating too much…

How to stop a shell shot? Development of armoring grades

Manoir Industries developed in the 60’s and 80’s the Manofort® alloys family for the defense industry, for example to equip tanks. The need was a really high strength, around 1000 MPa (ultimate tensile strength) and good impact properties, even at freezing temperatures. Qualification tests were done by real shooting on test sheets. The challenge was that strength and impact properties usually go in opposite ways. Still, those properties could be achieved by designing new low alloy steels with two…

The latest step in Manoir Diversification

In march 2016, Manoir Group acquired CTI Group. This French industrial group is specialized in boiler making and fabrication. This metallurgical expertise is complementary of Manoir UK plant located in Burton-on-Trent. CTI group has 3 industrial locations in France, namely CTI-ACDN, CTI-ACPP, CTI-Agriandre and counts around 400 employees. This strategical acquisition allows Manoir Industries to extend its portfolio of metallurgical expertise but also to propose additional products and services to both the Petrochemical and Nuclear markets. In addition, many industrial and operational…
