Description

Product material

TOKOTECH offered a wide range size of duplex steel welded coiled tubing. 2507/s32750 duplex steel welded coiled tubing is widely used in subsea oil well systems due to its long length. It has better corrosion resistance to seawater than common stainless steel, thus has a longer service life.
