Sulfuric Acid Plant

Our Plant Services offer construction management, supervision, and the dedicated workforce to get your projects done right and on-time.

Roberts’ core business is to provide construction solutions, resources, and support for facility owners and managers. We especially focus on capital projects, turnarounds, outages, renovations, and execution of repairs.

Relationships are at the heart of our business. Rather than focus on a single project or process, we strive for long-term relationships with our customers—relationships built around dependability, responsiveness, results, and most importantly, trust.

Unlike the typical construction contract method, Roberts can act as an extension of your facilities construction and support team. We can provide construction management, organize and execute contract scope, and even manage multiple projects at one time. This means less overhead and less headache for you and your team.

We take pride in responding creatively to construction and expansion challenges while still maintaining a results-oriented approach. Our teams are composed of seasoned professionals, whose experience and knowledge add value to projects of all sizes, complexity, and duration. We have experienced staff and craftsmen teams throughout the Southeast that have helped many of our clients complete their projects safely, on time, and within established budgets.

Our plant services have provided continuous on-site support to many industries for more than 40 years. We offer a full range of knowledge and skills necessary to keep your plant producing, including 24-hour emergency service personnel for turnaround and maintenance projects. Roberts has well trained civil, structural, erection, precision alignment, mechanical, piping, electrical, and instrumentation skilled craft personnel to completely support or supplement your needs during high load periods.

Our staff can turn-key install or repair complex systems or perform single task requests such as re-tube your heat exchangers, evaporators and boilers on-site. Though we are based in the Southeastern US, we believe that all your facility needs are local.

Quality Assurance and Control:

Roberts strictly adheres to a number of Quality Assurance and Quality Control Programs. As part of this process, we undergo yearly audits through our Authorized Inspection Agents and full audits every three years by the ASME and the National Board. Through the audit process and our ongoing internal efforts, we keep our quality program up to date with the latest amendments and revisions to the ASME code.

Our written Quality Control/Quality Assurance program is committed to zero defects both technically and aesthetically. All vessels are built to the same standards, whether code stamped or not. In addition to in-house radiography capabilities, we are equipped to perform various types of leak tests, (including Helium Leak Testing), proof tests, and ultrasonic thickness and material verification tests. We will develop a Project Specific QA/QC Program tailored for our clients’ unique needs.
