Prefabrication of piping for the construction of an ethylene plant in the United States.


Our teams were responsible for theprefabrication of the entire cooling system for this petrochemical complex expansion project in Texas. With a capacity of 1.55 million tonnes of ethylene produced per year, this new facility became one of the largest ethylene plants in the world. 

We prefabricated  more than 3,000 tonnes of piping in our workshops in Houston, Texas  .  At the customer's request, a large part of the 1,872 spools carbon steels with diameters that can vary between  80 "to 120" and thicknesses between 20 to 31 mm had to be subjected to heat treatments for stress relief after welding . As the cooling system is buried, all the welds were verified by magnetic particle (root), x-ray and vacuum tests .

These pipes, received beforehand, painted in FBE (Fusion Bond Epoxy) and retouched in our workshops after manufacturing, were also examined with aporosity detector (Holiday Detector) to guarantee the perfect application of the paint and its resistance to corrosion.
