Hatch’s Material Services Group ensures the reliability of critical equipment, utilizing the application of materials engineering, finite element analysis (FEA) design, and validation and quality management of the welding and fabrication processes. The Material Services Group provides materials selection, failure analysis, finite element stress analysis and design, welding application technology, welding inspection and fabrication management, QA/QC documentation creation, review, approval and control for all services.
Selection of the correct materials for project construction is a critical part of the application of successful engineering designs. Correct material selection can provide corrosion protection, prevention of equipment failures, and quality assurance during procurement of new equipment.
- Metals:
Carbon Steel; Stainless Steels (Ferritic, Austenitic and Duplex); Nickel Alloys; Titanium Alloys
- Non-metals:
Rubber linings; Elastomers; Plastics: Fiber reinforced plastic (FRP); Ceramics
- Materials evaluation and ranking studies, including the development and management of corrosion testing programs
Our materials-specialists are experienced in projects for oil and gas, infrastructure, underground mining, mineral processing, smelting, refining, and leaching of copper, zinc, lead and nickel.
Prepare and review specifications for material procurement; material fabrication; repair and inspection, including welding, casting, heat treatment, coating and lining.
Conduct failure investigation, metallurgical analysis and characterization, microscopy and electron microscopy, mechanical testing and corrosion testing.
Inspection and condition-assessment services can be carried out on equipment, such as Gas Cleaning Systems; Sulphuric Acid Plants; Furnace Lining; Gas desulphurization equipment, etc.
Visual welding inspectors are a key component in maintaining quality in the fabrication of critical equipment and structures by ensuring that the full scope of Hatch’s requirements are monitored during the fabrication process, including dimensional control of fabrications, schedule management and reporting. A firm understanding of the welding process and all related requirements is an essential component for the inspector in order to identify potential quality issues before they translate into lost time or revenue. The welding inspectors in Hatch’s Material Services group are welding technologists who are capable of bringing over 25 years of welding technical expertise to all areas of the fabrication process from design to construction.
Hatch’s welding services include:
- Global on-site welding inspection and fabrication management
- Developing weld and inspection procedures
- Quality audits and prequalification of fabrication vendors
Personnel certified to NACE CIP Level 1.
