We can adjust the depth of an analysis according to your financial or schedule constraints. Whether you need a complex or simplified analysis, ATSI will provide reliable results in a timely manner.

Engineering Analysis

ATSI can verify a proposed design, evaluate various design options prior to manufacturing or construction, or evaluate the impact of new service conditions on existing products or structures.

Design Verification Phase

By performing an analysis during the design phase, we can help you identify and solve potential problems. Problem resolution is often more expensive once a design is released into testing, production, or construction. An ATSI analysis during the design phase provides you with solid data to make a more informed evaluation of your design options.

Qualification Testing

An ATSI analysis can significantly reduce the number of tests required for production qualification. You will gain advanced insight into how a part will perform during testing. Our analysis can assist you in determining the cause of any failures and in pinpointing appropriate design changes. An ATSI analysis can help you to re-qualify a part in service when the applied conditions change. You will easily identify whether part modifications are required.

Failure-Mode Analysis

An ATSI analysis gives you invaluable information for determining the cause of failure of a part in service. Armed with this data, you can take prompt corrective action to prevent future part failures.

Heat-Transfer Analysis

Our methods accept temperaturedependent properties to provide more accurate results. An ATSI heat-transfer analysis will allow you to determine thermal stress in materials. You will be able to ensure proper designs and evaluations of failure modes. ATSI’s heat-transfer analyses have provided critical information for numerous applications, including blast furnace shell and components, heat regenerators, storage bins and silos, combustion air ducts, hot metal ladles, and pressure cooker vessels.

Piping Stress and Flexibility

ATSI can produce and analyze 3-D models of any piping system configuration. We can perform both static and dynamic analysis of piping systems. We have the ability to accommodate various materials, including FRP lines, steel, and exotic metals.

The ATSI Commitment

ATSI will provide accurate, highquality services tailored to individual project requirements. Our team is an extension of your own staff. ATSI adds value through responsiveness, field experience, and timely technical solutions.

From concept sketches, as-builts, and final design drawings to analyses and project documentation, we emphasize clear presentation of information, accuracy, and close attention to schedules. We pride ourselves on our ability to interface smoothly with engineering, operations, maintenance, and craft personnel.

ATSI works to minimize capital costs, maximize plant availability, and ensure ease of construction and maintenance. We measure our success by your satisfaction.
