Wyes & Laterals


Seamless forged Laterals and seamless forged Wyes, used primarily in high pressure steam lines and in high pressure subsea piping are subject to high thermal and reaction stresses due to excessive section thickness compared to the mating pipe. WFI’s unique manufacturing process allows us to produce these parts with maximum radiuses and a more uniform wall thickness which results in greatly reducing these stresses.
