SPECIAL FEATURE
Get Tough On Downtime With Corrosion Resistant Alloys To Cut Maintenance Costs
The oil and gas industry is currently facing unprecedented global challenges that require resilient and cost-effective metal solutions that perform without failure in hostile subsea, downhole, and onshore environments. The demand for premium quality, corrosion resistant exotic alloy metals that operate in increasingly demanding environments is therefore higher than ever across the globe.
Suppliers to this demanding industry that can provide high-performance, custom-made solutions to the problem of minimising downtime are in a good position to help their customers safeguard financial success by reducing downtime during maintenance and upgrades. The ability to process a wide range of exotic alloys that are resistant to corrosion is highly valuable.
Metallurgy experts such as AMETEK Specialty Metal Products (SMP) are seeing success in the industry as a direct result of their products being engineered for optimum toughness, hardness, and intensity. They are experiencing increased interest in how their metal products can deliver exceptional pressure, corrosion, and wear resistance in extreme working conditions.
Extended Operational Life Being able to rely on suppliers that can offer premium quality, corrosion resistant metal products gives the oil and gas sector a key commercial advantage. Reduced downtime and maintenance costs mean that energy companies can continue to deliver vital functions across critical infrastructure industries in the face of worldwide challenges to health, safety, and productivity.
Demand is increasing for specialist corrosion resistant metal products
Exotic Alloy Tubes up to 60,000 psi
engineered in higher strength alloys that deliver product longer life and enhanced performance. These products can be grouped into various categories, all of which play a crucial part in the overall workings of the oil and gas sector.
Exotic Alloy, “Fit and Forget” Tubes up to 60,000 psi Deployed in some of the most hostile downhole conditions up to 2,000m under the sea, oil and gas tubing operates in extreme environments. Critical applications include downhole hydraulic control lines, high pressure control and instrumentation as well as pressure housings. It is therefore imperative that tube systems offer high corrosion and pressure resistance up to 60,000 psi. These specialized properties ensure that product lifespans and quality remain high, not only to help reduce downtimes caused by necessary repairs, replacements or upgrades, but also leads to fewer part failures and lower costs when it comes to ongoing maintenance.
High-performance, ‘fit and forget’ alloy tubing can be manufactured in a range of exotic grades to offer a wide choice of materials for customers, including, stainless steel 904L and NORSOK-approved 6 Moly; as well as super duplex and high-quality nickel alloys like grades 825 and 625.
These types of tubes offer an excellent product life and significantly reduced downtimes for re-fitting traditional

corroded products, making them ideal for applications that demand long in-service life in hostile environments.
Hardfacing and Thermal Spray Powders for Coatings Metal powders are commonly used for thermal spray surface coating applications within this sector. Metal powder manufactured through water atomization enables a supplier to offer high levels of customization, including different levels of corrosion resistance from different types of alloys. Metal powders are engineered to have desirable thermal spraying characteristics that enhance the performance of the component being coated.
Metal powders are used to increase the hardness, wear, abrasion, and/ or corrosion resistance of the surface to extend a product’s lifespan and offer total component cost savings. High performance alloys used include Ni-Cr-Si-Fe-B family products, Ni- based corrosion alloys, and Co-based wear alloys that offer a wide variety of hardness levels and machinability. These products are highly sought-after for several deposition techniques, both with and without carbide reinforcement.
These products are commonly used for valving, pump components, corrosion protection, and flow path wear mitigation. Each alloy used is designed to allow for maximum density of the coating.
