Technical assistance on materials, welding and corrosion

ISQ has large experience and knowledge in the area of materials and their behaviour in corrosion and welding, providing technical assistance services to oil&gas, pulp&paper, petrochemical and power industries.

Technical assistance on corrosion

• Corrosion diagnostics and monitoring in water systems, including thermal waters; closed circuits such as fire and HVAC systems and boiler water circuits
• Assessment and analysis of efficiency of methods of chemical cleaning and passivation in water circuits, in particular of boilers Diagnosis and assessment of high-temperature corrosion mechanisms
• Corrosion protection systems specification through the use of corrosion inhibitors or by application of cathodic protection systems and/or coatings
• Corrosion resisting materials selection and specification

Technical assistance materials

• Materials characterization, identification and selection depending on application and assessment of its suitability to the environment and service conditions
