Weld Repair
Comprehensive Welding Procedures and Techniques
Equity has the engineering resources to assist in the development of weld procedures and techniques for both weld repairs and equipment modifications. Our welding expertise includes experience with the whole family of materials commonly used in process plant applications including carbon steels, low alloy materials, stainless and nickel based alloys, titanium as well as less commonly used materials such as aluminum.
We have been actively involved in weld repairs associated with heavy-wall hydroprocessing reactors, weld overlay applications in both a shop and field environment, heat exchanger tube-to-tubesheet issues, complex heat treatments which utilize our in-house mechanical engineering expertise to address thermal effects as well as repair issues associated with factors such as environmental and mechanical cracking in piping systems.
Equity engineers can participate in upfront engineering discussions with general contractors responsible for implementing a repair.


Mr. Young provides welding, metallurgy, and fabrication expertise to the refining and petrochemical industries. His responsibilities include consulting to Project engineering and plant site maintenance and inspection groups, assessment of the need and recommendation of the method for repair of existing equipment, welding procedure reviews for compliance to Code and project specifications, turnaround support technical expertise in the areas of welding, materials, inspection and fabrication.
Mr. Dirham’s materials engineering areas of specialty include high temperature creep analysis and remaining life assessments mainly of heater tubes and the susceptibility of equipment to High Temperature Hydrogen Attack. In the field of creep damage to heater tubes, he has extensive experience with the Omega strain rate testing method as well as remaining life prediction using the Omega method (with or without destructive testing) and the API RP530 method (without testing).
