The manufacturing of the U-tube heat exchanger to be used in the Oil Refinery in Iraq has been completed and shipped. The pipes with an outer diameter of 15.88 mm, a thickness of 1.65 mm, an opening length of approximately 11 meters, and a straight length of 5.5 meters were specially manufactured from England and brought to our country. The pipes were subjected to heat treatment after bending and stress relief was performed. Each pipe was individually subjected to hydrostatic testing and checked.
