SGS Baseline and High Temperature Hydrogen Attack Inspections for Pryor Chemical in Oklahoma
API type inspection services have been conducted by SGS at the Pryor, Oklahoma plant almost for a year. Furthermore, SGS has conducted internal inspections and condition assessment to baseline thickness and visual inspections at two separate ammonia plants and one urea plant, for diverse pressure vessels, heat exchangers and boilers during short maintenance outages. Based on the strength of the expertise of SGS in these types of inspections and evaluations and SGS boots already on the ground, PCC approached this experienced partner to carry out necessary baseline inspections and HTHA evaluation prior to start up of one of its three ammonia plants. Considering the advantages of SGS bundled services, PCC values a single resource for field inspections, engineering support, data management and overall asset integrity management (http://www.sgs.com/
Baseline and HTHA inspection project at the #1 Ammopac Ammonia Plant is expected to require maintenance outage for three weeks, the process planned to start on the second week of June. Although baseline inspection does not demand an outage, HTHA inspection (http://www.sgs.com/~/
Professional inspectors implement a specific SGS-developed procedure during the Pryor ammonia unit project and approach to identify and monitor HTHA appropriately and adequately. This methodology, crafted by SGS Industrial Services, will combine advanced signal processing and imaging of results collected at the Pryor ammonia unit while utilizing advanced techniques like time of flight diffraction (http://www.sgs.com/~/
The Pryor project will be provided by SGS with one API 510/570 pressure vessel and piping inspector and two Level II NDE technicians to conduct baseline examinations using ultrasonic thickness testing and PMI methods as well as P&ID review and isometric drawing creation. The HTHA team on-site in Pryor involves Level III advanced NDE specialist from the SGS NDE Competence Center in the Netherlands and two advanced NFDE specialists from the SGS Broken Arrow office in Oklahoma.
The two main aims of the Pryor project are establishing a baseline condition and HTHA inspection. Baseline conditions including thickness for process equipment and piping in each specific operating unit must be determined to offer an original guideline to which subsequent data will be compared in order to measure corrosion rates, schedule inspection dates and ultimately predict equipment life-expectancy
Extensive bundled services uniquely position SGS as an approved and trusted resource to provide all inspection and evaluation required for both project objectives meant to help PCC in meeting desired start-up schedules and fulfilling all mandatory requirements.
SGS is especially pleased to extend its services in Oklahoma and to further serve this prestigious partner.
