Umbilical tubes

Coiled tubing for cost-effective umbilical manufacturing

Alleima offers orbital-welded coiled tubing for cost-effective umbilical manufacturing. Our umbilical tubes are also offered in straight lengths, as long as 40 meters (131 feet), for a minimum requirement of orbital welds.

Umbilical tube materials

SAF™ 2507 (UNS S32750)
A super-duplex stainless steel that combines high corrosion resistance and high mechanical strength. With excellent resistance to seawater and marine environments, it is particularly well-suited for applications exposed to high stress in aggressive chloride-rich environments. The resistance to sour environments is superior to SAF™ 2205 (UNS S31803/S32205). PRE value min. 42.5 (valid for tube and pipe).

SAF™ 3007 (UNS S83072)
SAF™ 3007 is a super-duplex (austenitic-ferritic) stainless steel optimized for service in highly corrosive chloride environments where a high strength material is required. The new tube offers a safe, lighter, stronger and more efficient alternative to SAF™ 2507, the current industry standard.
