ABSTRACT:
A flanged pipe includes a pipe body portion, a flange portion and a bent portion located between the pipe body portion and the flange portion. The pipe body portion, the bent portion and the flange portion are formed from an integral, monolithic structure. A minimum inner diameter of the bent portion is smaller than an inner diameter of the pipe body portion. The flange portion has a first part having a thickness that is thicker than a thickness of the pipe body portion and a second part having a thickness that is thinner than the thickness of the pipe body portion. The flanged pipe has sufficient rigidity, strength and durability to attach the flange portion to other members or structures using a bolt through a hole formed in the flange portion.
