Large Engineered FCC Expansion Joints for a Petrochemical plant in the Far East
We have successfully designed, manufactured, tested and shipped three 78” FCCU Expansion Joints for an oil refinery in the Far East.
The client produces oil products, such as gasoline, naphtha, diesel, jet fuel, kerosene, fuel oil and liquefied petroleum gas (LPG) and petrochemical basic materials, such as ethylene, propylene and butadiene, etc.
The Expansion Joints have been designed as per UOP Standards and they will be installed at the refinery’s Fluid Catalytic Cracking Unit (FCCU).
