The ESAB FILARC 27P electrodes are low-hydrogen, specifically designed for downhill welding in circular pipe joints. The low-hydrogen content welding metal offers high crack resistance and excellent ductility, reducing the risk of cracks.

They are mainly used in conductors, compression stations, hot tapping, and related projects involving API 5LX52 to X70 grade steel pipes in the oil and gas distribution sectors, as well as in industrial piping systems.
