<p>PROBLEM TO BE SOLVED: To provide a hydrogen transfer tube which is durable even under low temperatures and high pressures and under high temperatures and high pressures and is flexible.SOLUTION: A hydrogen transfer tube includes: a first layer 110 having elusion resistance to hydrogen; and a second layer 120 as a distinct layer surrounding an outer surface of the first layer, formed of polyurethane in order to prevent permeation of hydrogen. The hydrogen transfer tube further includes: a first protective layer 130 disposed to surround the first layer and the second layer and providing shock resistance and heat resistance; and a second protective layer 140 disposed to surround the first layer and the second layer and providing shock resistance and heat resistance.</p> |
