Abstract
According to one aspect, a tubular structure may include a base and a wrap. The base may have a first surface and second surface opposite one another, the first surface defining an elongate cavity, and the base having a tubular shape defining a longitudinal axis extending along the elongate cavity. The wrap may be supported on the second surface of the base, the wrap including a plurality of layers, and each layer having a first longitudinal edge and a second longitudinal edge coupled to one another along a respective spiral seam associated with the given layer and extending about the longitudinal axis of the base.

A tubular structure comprising:
- a base having a first surface and a second surface opposite one another, the first surface defining an elongate cavity, and the base having a tubular shape defining a longitudinal axis extending along the elongate cavity;
- and
- a wrap supported on the second surface of the base, the wrap including a plurality of layers, and each layer having a first longitudinal edge and a second longitudinal edge coupled to one another along a respective spiral seam associated with the given layer and extending about the longitudinal axis of the base, wherein the base and each one of the plurality of layers are metal, a first layer of the plurality of layers is joined to the base via a first weld penetrating into the base, and a collective thickness of the wrap and the base varies in a direction parallel to the longitudinal axis of the base.
