In the construction of storage tanks, wind girders (or stiffening rings) play a critical role. They prevent the tank walls from buckling under wind loads, especially when the tank is empty, ensuring structural stability and safety. However, when these girders are compromised by corrosion, the entire tank structure becomes vulnerable. The Challenge: A renowned chemical […]
The Problem A critical end suction pump used in a continuous service application suffered severe corrosion throughout its inner casing. Over time, the harsh operating environment led to pitting and rusting of the metal surfaces, significantly compromising the pump’s performance and efficiency. The client faced a pressing challenge: the need for a quick, cost-efficient repair […]
In the maritime industry, corrosion control is a constant challenge, especially for vessels exposed to harsh seawater environments. This case study covers the successful repair and protection of the stern pipe of the Coastal Sathwa vessel, demonstrating the importance of advanced repair materials and processes.
Introduction: The Urgent Need to Combat Corrosion Under Insulation (CUI) Corrosion Under Insulation (CUI) is a significant challenge for industries that rely on insulated piping and equipment, such as the oil, gas, and chemical processing sectors. CUI accounts for up to 10% of all corrosion-related costs in these industries and is responsible for 60% of […]
A renowned entertainment and hospitality group faced a significant challenge when severe pitting was discovered on the hull of their 90-meter-long casino ship. The ship had been in continuous operation in water for six years, making maintenance difficult. The cause of the problem was identified as broken anodes, which led to over 2000 pits on […]
