Carbon steels can easily deal with gaseous chlorine at low temperatures and in the absence of moisture. But if water is present, chlorine becomes vigorously corrosive to several metals. In the same manner, dry hydrogen chloride is not corrosive to various metals. As soon as it is dissolved in water HCl is developed and it … Continue reading How do different alloys perform in dry and moist chlorine media?

The influence of hydrochloric acid concentration on the corrosion rates of Monel 400 and nickel in air-free and air-saturated solutions at 30oC. It will be noted that the corrosion rates of Monel 400 and nickel at room temperature are about the same 10% acid concentration. In this concentration limit, the corrosion rates of both materials … Continue reading Influence of different HCl concentrations on Monel 400 and Nickel

Corrosion in chemical processing media often reduces with increase in their pH level. In alkaline solutions, hydrogen ions are usually present in nominal magnitudes. Although, various metals can withstand some pH, often basic in nature but experience severe corrosion with increase in pH level. Usually alkali corrosion is led by pitting and other types of … Continue reading Which high nickel alloy provides the best performance in alkali media

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

Chemical processing refers to the method of altering one or more compound or chemicals with the help of chemical reactions. The process makes use of several equipment such as heat exchangers, evaporators, flanges, pressure vessels, fittings, valves and pumps. Due to extreme conditions prevailing in the operations that are often found in the solutions that … Continue reading Applications Of Hastelloy C276 In Chemical Processing
