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…

Centrifugally Cast Tubes

During the 1970’s, Manoir Industries developed its industrial tool with the most modern equipment regarding the casting of centrifugally spun tubes. Through its very modern equipment, the factory is highly specialized in this field and is amongst the top tier of tube suppliers all over the world. A large number of automatically regulated machines of all sizes using an extensive range of dies of various dimensions enabled Manoir to meet the most stringent requirements of our customers. Back then, the…

Quality & continuous improvement Centricast line

Continuous quality improvement is a management philosophy that organizations use to reduce waste, increase efficiency, and increase internal (meaning, employees) and external (meaning, customer) satisfaction Christophe, 42 years old, Quality & continuous improvement Centricast line What was the reason of your application at Manoir? You know, I have 2 brothers in law currently working at MANOIR. I decided to volunteer in 1994 when I knew MANOIR foundry was actively looking for people.

Producing closer to our customer: Manoir fabrication network – Howell Industries – USA

Manoir Industries and Howell Industries signed their industrial partnership in 2015, to propose local fabrication and assembly for their North American clients. Under this partnership, Howell Industries has been certified according to Manoir quality standards for its assemblies and fabrication of Manaurite® high alloy tubes, fittings and ancillary equipment for ethylene, hydrogen and direct reduction of iron furnaces. Howell Industries has been established in 1965 and has developed key competencies for the welding of high alloys, in particular for the…

Improved properties at lower cost in reforming: from UK to HP and much more

Improved properties at lower cost in reforming: from HK to HP and much more Heat-resistant steels dedicated for use above 800°C are mainly composed of chromium (for corrosion resistance purpose), nickel (for creep resistance) and iron. The most widely spread type of steels used for steam reforming applications, where high temperature and high pressure do apply, are from HP family. HP family is composed of various steel grades composed of 25 wt% of chromium and 35 wt% of nickel. Initial…

Argon Oxygen Decarburization- AOD converter, the mandatory road to the highest quality steel

The AOD is a process to purify the steel which is subject to 3 steps of refining: decarburization, reduction and desulphurization. This leads to eliminate the impurities from the melt. In 2014 Manoir invested heavily in modernizing its AOD equipment, which has been originally installed in the 1970’s in order to be able to produce very high volumes (20T) of stainless steels to manufacture parts intended primarily for nuclear power plants. This process is also key to achieve required mechanical and…
