Project Location

Strong corrosion exists

Zero leakage is required

High chemical purity must be maintained

Frequent on/off operation is needed

Ethylene & Large Petrochemical Complexes​

The Challenge: Massive scale, high pressure, and the need for strict international compliance (ANSI/DIN/JIS).
Our Solution: Comprehensive fluid control packages for downstream ethylene processing, from large-bore lined butterfly valves to complex piping layouts.
  • Key Projects: Integrated Petrochemical Complexes (as seen in our project site photos).
  • Safety First: Fire-safe designs and rigorous pressure testing before shipment.
