How we can service the petrochemical industry

Nickel & nickel alloys alongside stainless steels are used extensively in the petrochemical industry due to their excellent properties such as corrosion, heat and pressure resistance. They are resistant to both aqueous and gaseous corrosion plus they can be used in environments from cryogenic to very high temperatures. Steels are used in every part of the industry from production to processing to distribution of refined products. The addition of nickel to the steel alloys increases their strength and corrosion resistance. Titanium is also added to increase strength, density and corrosion resistance, these alloys are widely used in down-hole tubing. Additionally titanium is highly resistant to seawater, carbon dioxide and hydrogen sulphide corrosion and can maintain it's strength at –240F, the temperature required to liquefy natural gas. Chromium is also added to steel alloys to increase resistance to carbon dioxide and hydrogen sulphide, it can also withstand temperatures above 435F which are found in the deepest oil and gas wells. Molybdenum is another metal which is added to steels to increase strength and corrosion resistance, these steels containing 2-4% Mo are used for gas pipeline construction. Manganese, cobalt and vanadium are also added in varying amounts.

A wide variety of metal powders are also used in powder metallurgy produced parts, hard facing and brazing & welding applications for the petrochemical industry.

Copper and its alloys are widely used due to their excellent thermal conductivity and cryogenic properties, they can be found in valves, stems, seals and heat transfer applications. Bronzes with nickel and aluminium additions are often used in wellheads and blowout prevention valves. Precious metals are also often used as catalysts for refining transportation fuel products; generally palladium and platinum are used although ruthenium, rhodium, osmium and iridium can also be used.
