With the passage of time, oil and gas exploration will be performed in deep wells specifically in deepwater. Unlike to shallow wells, the deep wells demand durable materials. The well conditions include hydrogen sulfide, carbon dioxide, chlorides and sulfur and also the temperatures go up to 260oC and pressure 25000 psi.  Due to this, it … Continue reading Materials for deep well, gas and water exploration applications

Monel belongs to the family of nickel-based alloys. It chiefly consists of nickel and copper while silicon and carbon are present in a smaller amount. The contents of this alloy when fabricated using machining, welding and hot-cold working are known to offer better strength. Monel 400 is also known as high resistance alloy that exhibits … Continue reading What makes Monel 400 ideal for Gas Industries

The use of materials in marine applications has conventionally been linked with ships. Over the years, although new materials have been developed. Known in industries such as desalination and oil and gas production, additionally the need of large volume of cooling water in the industry usually demanded establishment of plants along the ocean specifically in … Continue reading Applications of Nickel base alloys in stagnant and flowing Seawater

A major limitation of stainless steel is that it is highly susceptible to chloride based localized attack like crevice, pitting and stress corrosion cracking. Hastelloy C276 is the most resistant nickel based super alloy to the chloride based localized corrosion that limits the applications of austenitic stainless steels. In various cases, stress corrosion cracking was … Continue reading How Nickel based super alloys are superior to traditional stainless steels

In alkaline solutions, hydrogen ion is present in nominal concentrations. Usually, the alkali corrosion causes pitting and other localized attack due to the production of cathodic layers and the corrosion is more severe in anodic regions. Austenitic stainless steels and other low nickel materials may experience stress corrosion cracking or general corrosion in hot concentrated … Continue reading How do Nickel and Inconel alloys perform in caustic media
