In August, the company received a first partial order to supply almost 6,500 m (21,325 ft) of metallurgically clad pipes (10-in. OD).
In October a second order for about 73 km (45 mi) of mechanically lined BuBi pipes (10-in. OD) and 4,200 m (13,779 ft) of metallurgically clad pipes (14-in. OD) was placed. The pipes were ordered in the material combination of carbon-manganese steel and corrosion-resistant alloy.
According to the company, the use of clad materials in pipe manufacture combines the properties of strength and toughness of carbon-manganese steels with the corrosion resistance of stainless steels.
Located about 185 km (115 mi) offshore São Paulo, the Bacalhau oil field is in the presalt Santos basin in approximately 2,050 m (6,726 ft) of water.
Bernd Harborth and Berni Reimer, Project Managers clad pipes, said: “The pipes are exposed to high tensile loads due to the 2,050 m water depth. To withstand these conditions, maximum options for wall thicknesses, dimensional tolerances, and material properties will be used during production.”
