- Product Features
High corrosion resistance and Heat Resistance
High corrosion resistance and heat resistance make the stainless steel pipes usable under many different working conditions in chemical plants.
Consistent Quality
Stainless steel pipes are produced using TIG and plasma welding up to 400A, which is not available at other plants in Korea. Large-diameter steel pipes of 450A~1200A are produced by the roll bender system.
Superior internal bead treatment
The cold rolled system, which is the most advanced system to date, is used to eliminate inner beads, thereby improving the microstructure of welded areas.
Advanced Technologies
U-tubes for nuclear power, which had previously always been imported, were successfully developed by SeAH, and are now being distributed to KEPCO and other customers.
Strict Quality Control System
Pipe production facilities specially designed by SeAH and its computer-aided cutting system are contributors to the manufacturing of high-precision products.
