XPRESS CARBON STEEL TUBE
(SC640) TECHNICAL CHARACTERISTICS
XPress Carbon tubes are thin-walled XPress Carbon Steel tube Unalloyed ULC (Ultra Light
precision tubes manufactured in Material Carbon) Carbon steel, Rst 34-2 Mat. No. 1.0034 according
to EN 10305-3
accordance with EN 10305-3 (previously
DIN 2394/NEN 1982) from a special
kind of steel that has a very low carbon Approvals CSTBat, DNV, GL, RINA
content. The resulting product is very
easy to bend. The absence of leaks is also Tolerances According to EN 10305-3
checked, in accordance with EN 10246-1,
so that all tubes will be guaranteed leak
free. Finishing Zinc coating of at least 8-15µm. The tube welding seam
is subsequently galvanized on the outside. Inside of the
tube is protected by a thermally applied oil film.
