摘要： The multiple pipe component is a pipe made up of at least an inner pipe and an outer pipe in which a fibrous filler is positioned between the outer pipe and the at least one inner pipe in a region that will be bent. The filler is formed with slits spaced at given pitches. Holes are provided in the inner pipe on at least one of the downstream side and the upstream side of the inner pipe in the bending region while holes are not disposed in the bending region.

摘要： A pipe bending apparatus for performing a pipe bending method, wherein the method includes filling a workpiece with a liquid, pressurizing the liquid to a target pressure level, and bending the workpiece to create a bent pipe. Preferably, the pressure level is inversely proportional to the radius of the bend in the pipe. Furthermore, preferably the pressure is directly proportional to the bending angle of the pipe. Preferably, the pressure is maintained substantially at the target pressure during the bending process. Optionally, the pressure level can be increased during the bending process.
摘要翻译：一种用于执行管道弯曲方法的管道弯曲装置，其中所述方法包括用液体填充工件，将所述液体加压到目标压力水平，以及弯曲所述工件以产生弯管。优选地，压力水平与管道中的弯曲半径成反比。此外，优选地，压力与管的弯曲角成正比。优选地，在弯曲过程中，压力基本保持在目标压力下。可选地，可以在弯曲过程期间增加压力水平。
