Piping Operations for the Hybrid Cooling Tower Construction Project

Project overview and importance

The hybrid cooling tower construction project at the southern refinery of Isfahan Oil Refining Company is one of the important infrastructure projects aimed at improving the efficiency and sustainability of refining processes. In this project, our company was responsible for the complete implementation of piping operations and carried out all stages of design, construction, installation and testing of pipelines related to the hybrid cooling system.

Technical and Execution Challenges

  • Design and installation of cooling water, return, and feed pipelines for the hybrid cooling tower based on approved engineering drawings.
  • Fabrication and on-site installation of piping spools, fittings, and steel supports in full compliance with industrial standards.
  • Execution of welding, fit-up, alignment, and NDT operations in accordance with ASME B31.3 standards.
  • Performance of hydrostatic and pneumatic tests to ensure pipeline integrity and reliability.
  • Final painting and insulation to provide resistance against corrosion, humidity, and high operating temperatures.

Omran Sanat Olia’s Approach and Expertise

Due to the hybrid technology applied in the cooling tower, the piping design and execution required high precision and close coordination with mechanical and electrical disciplines.
Key actions contributing to the successful execution of the project included:

  • Full compliance with HSE requirements and special safety procedures within the refinery’s operational environment.
  • Detailed execution planning to align installation phases with the client’s project schedule.
  • Utilization of modern equipment and advanced welding quality control tools, including WPS and PQR procedures.

Achievements and Outcome

  • Successful project delivery within the defined schedule and with high execution quality.
  • Improved cooling system efficiency and a significant reduction in water consumption across process units.
  • Full client satisfaction (Dariz Engineering Company) with the execution methodology, team discipline, and final project results.
