Project Background – Petrochemical Expansion in Turkey
With increasing global demand for petrochemical products, major refining and chemical processing facilities in Turkey are expanding their storage and transfer infrastructure.
This project involved the expansion of a coastal petrochemical complex, requiring a robust pipeline system to support:
Large-volume chemical storage transfer
Continuous production operation
Integration with marine logistics terminals
Long-distance industrial pipeline networks
Due to its coastal location, the system faced intense chloride exposure from sea air and chemical media, making material selection critical.
Project Overview
The client required a high-capacity pipeline system for transferring chemicals between:
Storage tanks
Processing units
Marine loading terminals
To meet these demands, we supplied:
👉 ASTM A409 316L stainless steel welded pipes (34" large diameter)
for the main chemical transfer pipeline system.
Key Engineering Challenges
1. High Chloride Corrosion (Coastal Environment) 🌊⚠️
The project site is located near the coastline, exposing pipelines to:
Salt-laden air
High humidity
Chloride-induced corrosion
👉 Combined with chemical media, this creates:
Accelerated pitting corrosion
Surface degradation
Risk of leakage
2. Chemical Transfer Corrosion Risk
Transported media included:
Acidic chemical liquids
Petrochemical intermediates
Process fluids with corrosive properties
👉 Standard materials showed:
Internal corrosion
Reduced service life
3. Large Diameter Flow Requirement (34") 🌐
High-volume chemical transfer needed
Stable flow distribution required
Pressure drop must be minimized
4. Structural Stability in Industrial Environment
Heavy-duty pipeline network
Long-distance routing
High mechanical stress conditions
