Oil & Gas-Wear Solutions

Corrosion Wear-Chlorine gas

   The growing demand for hydrocarbon resources has resulted in accelerated increase of oil production. Oil sands conveying requires erosion & corrosion resistant piping. This can be achieved by providing an extremely wear resistant material which can operate even at elevated temperatures. The presence of carbon dioxide (CO²), hydrogensulphide (H²S) and free water can cause severe corrosion problems in oil and gas pipelines. Internal corrosion in wells and pipelines is influenced by temperature, CO² and H²S content, water chemistry, flow velocity, oil or water wetting and composition and surface condition of the steel. A small change in one of these parameters can change the corrosion rate drastically due to changes in the properties of the thin layer of corrosion products that accumulates on the steel surface.

Ceramic liners provide the cost effective solution to achieve the production rate desired without loss in downtime or sudden maintenance.
Our products are lined with silicon carbide liners which has the highest wear resistant compared to any other metal. SiC is also universally corrosion resistant even at elevated temperatures. Corrosion-resistant alloys such as 13% Cr steel and duplex stainless steel are often used downhole and, recently, also for short flowlines. For long-distance, large-diameter pipelines, carbon steel is the only economically feasible alternative and corrosion has to be controlled by chemical additives to the transported fluids.
Using ceramics inside the pipe as the wetted components will provide considerably high cost savings over an extended period of time.

Well head piping-Erosion & Corrosion

    Ceramics have now taken the lead role in the oil & gas industry in solving erosion & corrosion problems. Ceramics like sintered silicon carbide offer the highest wear resistance as compared to any other liner or alloy in the materials family.

Ceresist designs piping as per ASME codes and ensures that the wetted parts are always ceramic to ensure continuous operation and minimal downtime. Our piping is designed to last  36x times longer than carbon steel piping. Sand erosion is a major concern in the industry especially when conveyed at high velocities will wear out steel or alloy piping. 

Sand particles from oil and gas production may cause considerable erosion damage in critical parts of transport and processing equipment such as valves and chokes. Increased longevity of such components will lead to significant savings as offshore oil and gas production move subsea, and it can be achieved in two ways; through selection of erosion-resistant materials or through design optimization.

A total of 28 different materials including standard steel grades, solid tungsten carbide materials, coatings and ceramics have been tested under various impact angles and velocities of sand particles, and examined for erosion characteristics. Alpha sintered Silicon carbide & Reaction Bonded Silicon Carbide have shown the least wear resistance. This proves that with proper design these are the long term solutions for the oil & gas industry.
