Pressure Vessel Design
Pressure vessel design solutions for reactors, drums, storage tanks, columns, heat exchangers and more — total engineering from strength calculation and thermal calculation to FEA stress analysis.
Design · Domestic Certification and Inspection · Import Vessel Certification — Founded 1998, Pressure Vessel Engineering Specialists
Across petrochemicals, fine chemicals, secondary batteries, bio, pharma, food, new materials and energy — a trusted total plant engineering partner for 30 years, accountable from design optimization to domestic and global certification.
Seoeun Plant Tech is a specialist in total engineering solutions — pressure vessel design, process design, testbeds, strength calculation, stress analysis and safety certification — across petrochemicals, bio, pharma, nuclear, hydrogen, food and new materials.
With over 2,800 import vessel certifications and many certification-consulting projects delivered, we work closely with major domestic and international certification bodies to provide the optimal technical solution for every client.
Since our founding in 1998, relentless innovation has set new standards in plant engineering across pressure vessel design, pressure vessel certification and pressure vessel inspection.
