We can evaluate, inspect, maintain, design, analyze and improve various types of equipment, including electronic and mechanical equipment. Our qualified engineers and professionals will work with clients to eliminate or reduce downtime for fixed and rotating equipment, instrumentation, and control systems. Our product knowledge and insight enable us to develop optimal solutions, and we work closely and in strict confidence to understand our customer’s specific needs, concerns and requirements. We also believe in the philosophy and practice of Concurrent Engineering. We can avoid costly and unnecessary revisions by early involvement with the project and work closely with our customers’ staff.

FFS (Fitness for Service) is an essential concept in process industries. FFS is the ability to demonstrate the structural integrity of an in-service component even though it contains a flaw. This serves as a rational basis for defining flaw acceptance limits and allows engineers to distinguish between benign and dangerous defects. Pittsburgh Mineral & Environmental Technologies (PMET) provides FFS for all damage mechanisms, including:

• Fracture analysis
• Fatigue analysis
• Elevated temperature evaluation
• Failure evaluation
• Crack-like flaws
• General and localized corrosion
• Blisters and HIC/SOHIC damage
• Weld misalignment and shell distortions
• Fire damage
• Dents, bulges, and laminations

FEA (Finite Element Analysis) is an approximation method of mathematically defining a structure’s geometry and prescribed loading (boundary conditions). We can provide a complete or partial 3D model of any structure or component. The extent of the modeling depends on the symmetrical boundary conditions. We can offer the following analyses for your assets and operations: Structural static analysis – steady-state and transient

• Static or dynamic analysis
• Modal analysis with harmonic response analysis
• Transient dynamic analysis
• Thermal analysis
• Spectrum analysis
• Buckling analysis
• Linear and non-linear analysis
• Fracture mechanics
• Composite analysis
• Fatigue analysis

Our welding engineers are recognized experts in adapting and developing welding procedures for new materials or to meet special project requirements. In addition, Pittsburgh Mineral & Environmental Technologies (PMET) offers a range of welding engineering and field support services, from working with clients during design and fabrication to responding to an emergency in an operating facility.

• We can review supplier procedures and production, welding practices for quality and cost-effectiveness, develop new welding procedures, set up a job site test shop and welder training program, and train project personnel to become welding inspectors and meet the American Welding Society requirements. We also work with client suppliers to verify that specific welding procedures are followed during fabrication.
• Our Certified Welding Inspectors can visit supplier shops to review welding procedures and confirm compliance with codes, standards, and specifications. We work with suppliers to solve manufacturing problems and help maintain production schedules without compromising quality. We also help clients evaluate subcontractor manufacturing capabilities and quality control and assurance programs.

Identifying and reducing risk at industrial facilities is a crucial management function. “How did it happen” is likely the first question senior staff and managers ask after a workplace accident. Therefore, identifying the root cause of an incident, so it does not happen again is a priority of our failure analysis professionals who work with clients to make significant improvements in system design, employee safety, and process safety, thus reducing the probability of repeated accidents.

• We can assist in performing a damage mechanism assessment and developing corrosion control documents with informational integrity operating windows. The process starts with an overview meeting with client operations, inspection, and engineering staff to review the process operation shown on each process flow diagram (PFD).
  • The process overview will involve a detailed review of the PFD process streams to obtain the information needed to identify damage mechanisms and anticipated damage rates. Specifically, the Pittsburgh Mineral & Environmental Technologies (PMET) and client teams will identify operational and equipment history data/information such as operating conditions parameters, process stream constituents, fluid states, operating modes, failure histories, insulation conditions, and humidity areas as applicable. Also, we will identify and generate a list of equipment records and data, such as piping specifications or equipment datasheets, needed to complete the damage mechanism assessment.
  • Based on these data, our engineers will work independently to identify the damage mechanisms and anticipated damage rates to provide:
    • Set of PFDs with corrosion loops identified
    • Set of corrosion control document tables with the initial assessment of the identified damage mechanisms and anticipated damage rates
    • Integrity operating windows anticipated for each process stream

• Resourceful people, skilled and dedicated to executing the project, are our keys to sound project management. We provide those people with appropriate project management systems to plan and forecast results. In addition, the interrelationship of our core activities and our geographical spread provides synergy and opportunities for the cross-fertilization of ideas and services.
  • The experience we have accumulated on large projects enables our project managers to combine the requirements of our clients with the logistical and technical support needed to accomplish each task, from mobilization to reporting. Moreover, due to our extensive international presence and experience, these efforts are seldom hindered by geographic location, local culture, or commercial practices.
