PRODUCT 01

Seamless steel pipe — API 5L, ASTM A106, A53 and A335

Hot-rolled and cold-drawn seamless pipe with no weld seam, produced from a pierced billet so the wall is continuous around the circumference. It is the default choice where pressure, temperature or bending stress rules out a welded seam.

PRODUCT 02

Line pipe — API 5L PSL1 / PSL2, bare or 3PE and FBE coated

Transmission pipe for oil, gas and water lines, supplied bare or with an external anti-corrosion system. We match the coating to the burial condition: 3PE and 3LPE for buried and wet service, FBE where the pipe is to be concrete weighted or the soil is aggressive, internal epoxy where the medium attacks carbon steel.
