Materials Evaluation and Testing Services

Summary

Due to corrosion and a variety of other degradation causes of materials used for process plant equipment, it is crucial to know the mechanism of such deteriorations for purposes of materials selection or remaining life assessment.

TOYO has in-depth knowledge, capability, and experience for evaluation of materials properties through corrosion tests for materials selection as well as metallographic examinations for failure analysis.
TOYO provides materials evaluation and testing services for new process developments and diagnosis of existing plants.

Features

TOYO's expertise ranges from a lot of experience and knowledge in material engineering as well as corrosion test under specific conditions such as high temperature and high pressure environments.

TOYO provides a full range of technical services from development of a test cell to data analysis and provide complete solution by involving process engineers, mechanical engineers as well as material engineers.

TOYO utilizes advanced research laboratories or institutes, when necessary, to meet the Client's needs.

Services

Corrosion is significantly influenced not only by nominal composition of process fluid condition but also by a small amount of certain corrosive species. Electrochemical corrosion test under simulated condition with such contaminants is an effective way for materials selection.
Based on such corrosion test simulating high temperature and high pressure operating plant conditions , TOYO evaluates corrosion resistance of materials. In addition, TOYO provides a technical advisory service on cost-effective materials selection based on a long-term experience in process plant engineering.

Material degradation is a phenomenon caused by interaction between metallurgical characteristics of material, such as chemical composition, heat treatment and forming condition of materials , and environmental conditions. In plant maintenance, a proactive approach to implement improvements ahead of equipment failures based on data and information on such material degradations, is becoming more and more important.

By using the knowledge base for materials engineering, TOYO provides a technical service to assess mechanical integrity of equipment or remaining life as well as an evaluation service of aged materials.
