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…

Building a nuclear power plant, Manoir Industries expertise defined the stainless steel primary loops

Pressurized water reactors are today the most common functioning nuclear powerplants. They are designed with three successive coolant loops. The primary loop drives the heat extracted from the nuclear reaction towards steam generators. The steam generated within secondary loop then drives steam turbines that generate electricity. The coolant water within primary loop circulates within the reactor. It is highly pressurized at around 150 bar to remain liquid at high temperatures (350°C). The primary loop is a critical component that…
