Abstract:
1. A level wound coil (LWC)-mounting pallet, comprising: a pallet; and an LWC comprising a plurality of coil layers each of which comprises a pipe wound in alignment winding and in traverse winding, a coil of a (m+1)-th coil layer being located such that a pipe at a start position thereof is fitted into a concave part formed between a pipe at a lower end and its adjacent pipe of a m-th coil layer outside of the m-th coil layer, where, when the LWC is disposed on a mount surface perpendicular to a coil center axis of the LWC, m is an odd natural number if a start position of the winding of the LWC is located at the upper end and m is an even natural number if the start position is located at the lower end; wherein the one or more LWC is mounted directly on the pallet or through a cushioning material on the pallet, wherein the LWC comprises a shift section where the pipe is shifted from the m-th coil layer to the (m+1)-th coil layer on a bottom surface thereof when the LWC is disposed on the mount surface, wherein the shift section comprises a k-th shift section on an inner layer side and a (k+1)-th shift section on an outer layer side, where k is a natural number, and a start point of the (k+1)-th shift section does not transit, relative to a start point of the k-th shift section, in a reverse direction to a winding direction of the pipe, and wherein the pallet or the cushioning material comprises a recessed area that is formed at all or a part of a portion of the pallet or the cushioning material to face the (k+1)-th shift section not transiting in the reverse direction.
