ISCO's Production Lines
were designed by Hoesch, Germany and PRD,USA, respectively
employing two different technologies, namely external cage forming versus free
method is Submerged Arc welding (SAW), which is an automatic process with very
high quality output. These pipe mills can also produce steel quality up to grade
X70 according to API5L standards.
the weld quality, pipes will be ultrasonic tested continuously by an in-line
ultrasonic testing facility applying back pulse echo method. After Cutting the
pipe to the desired length it will be pressure tested with test pressure being
1.5 times the target pressure to ensure proper pressure resistance. After Hydro
test, both pipe ends are beveled and after final inspection and in-line
weighing, pipes will be transported to the pipe storage area.
