Designed to prevent primary water stress corrosion cracking, ultrahigh pressure cavitation peening can extend the life of nuclear reactor primary components, including the hot leg primary nozzles, for up to 40 additional years.
Many industrial accepted standards for pressure design address all aspects of piping design for chemical plants and refineries; none discuss all of the considerations for metallurgical selection. These code standards do list materials that are acceptable for use in chemical plants and refineries.This paper discusses some but not all of the resources that a designer can reference in properly selecting materials for an application.
Quaker Chemical Corporation has expanded its product offering in the steel industry with the addition of PRIMECOAT Surface Treatments and QUAKERTEK Specialty Greases. The Quaker PRIMECOAT Surface Treatment portfolio is used in the passivation process by which metal surfaces are converted into a protective corrosion preventing film that improves corrosion protection and exhibits excellent compatibility with paints and adhesives and good lubrication properties.
Outokumpu has started a strategic review of its high performance alloys or VDM business unit. During this review, Outokumpu will evaluate strategic options for VDM and consider how best to drive continued growth and profitability for the business, within or outside of Outokumpu.
Metallized Carbon Corporation, a global leader in the manufacture of oil-free, self-lubricating, carbon graphite materials for severe service lubrication applications, announced the availability of the Grade M 312 nickel chrome impregnated, carbon graphite material. This material is ideal for use in sleeve bearings for power plant boiler feed pumps, where the extreme conditions require high corrosion resistance.
Engineering firms Magma Global and Airborne are competing to develop piping in the challenging environments such as in Brazil and the Gulf of Mexico with regard to heat and corrosion. For years, steel piping has dominated oil and gas market but with projects in Brazil's pre-salt going beyond 2,000m under the sea and corrosive enhanced oil recovery techniques now used widely, companies are looking for more flexible and durable materials.
