Hydraulic pipe BuBi®

for hydrocarbonsfor gasfor fuel

At the beginning of the nineties we developed the mechanically lined BUTTING-Bimetal-pipe, short: BuBi® pipe. The BuBi® pipe is a corrosion resistant pipe which is telescopically aligned inside a pipe in carbon-manganese material and the tight mechanical bond between the pipes is achieved in a hydroforming facility. For many years the BuBi® pipes have been successfully used in very demanding and sensitive onshore and offshore areas of the oil and gas industry. They are used as pipelines, riser pipes and SCR-pipes for highly corrosive media. Technical details at a glance: Production acc. to API, ASTM, DNV or ISO Suitable for S-Lay, J-Lay method, bundle or reel-lay process Advantages of mechanically lined pipes: Cost savings of up to 40 % compared to solid pipes High corrosion resistance at the inside and high pressure resistance at the outside Project-specific material combinations
