Flexible hose and method for manufacturing

摘要

The present disclosure relates to a flexible metal hose including a continuous metal strip having rounded lateral edges. The continuous strip is wound in a helical pattern to form a cylindrical hose body. The strip has a generally S-shaped cross section including an inner hook portion and an outer hook portion. The strip is helically wrapped such that the inner and outer hook portions of adjacent wraps interlock to form flexible joints of the hose.
