Abstract: A low temperature fluid dual structure pipe includes: an inner pipe through which a low temperature fluid flows; and an outer pipe externally fitted to the inner pipe with a sealed tubular space therebetween. An inactive gas having a melting point and a boiling point each of which is equal to or higher than a temperature of the low temperature fluid is filled in the tubular space between the inner pipe and the outer pipe. When the low temperature fluid flows through the inner pipe, the inactive gas is liquefied or solidified, and therefore, at least one of a liquefied inactive gas layer and a solidified inactive gas layer is formed on an outer peripheral surface of the inner pipe. As a result, a pseudo vacuum layer that is in a substantially vacuum state is formed in the tubular space.

Abstract: A high-pressure tank includes a container main body (10) constituted of a body (11) and dome portions (12) disposed on both ends of the body, and a reinforcing layer (20) formed such that a fiber member is wound around an outer periphery of the container main body. The reinforcing layer includes a hoop winding layer (40) formed by hoop winding that winds the fiber member such that a winding angle is approximately perpendicular to a central axis of the body, and a high helical winding layer (30) formed by high helical winding that winds the fiber member such that a winding angle is inclined with respect to the central axis compared with the hoop winding, and the high helical winding layer extends to the dome portion. The high helical winding layer includes a thick portion having a thickness at an outer side part of a boundary position between the body and the dome portion, which thickness is thicker than a thickness at a part positioned on the body. The hoop winding layer is formed from the body to the dome portion where the thick portion is formed, as a layer at an outer diameter side of the high helical winding layer.

Abstract: A composite pressure container for fluids includes a pressure container, a boss (1), and a coupling or valve member (5) fitted in an opening in the boss. The pressure container includes an inner fluid-tight liner layer (4) and a pressure supporting layer (3) formed by winding fiber-reinforcement onto the liner layer.

Abstract: A pressure vessel has an interior chamber and includes an outer shell, a boss, and an internal liner disposed within the outer shell. The boss includes a port extending between the interior chamber and an exterior of the pressure vessel; and an annular flange extending radially from the port and having an exterior surface and an interior surface. The liner includes an exterior portion adjacent the exterior surface of the flange; an interior portion adjacent the interior surface of the flange; and a vent in the interior portion. A method for forming a pressure vessel includes mounting a boss on a mandrel, flowing a non-metallic polymer around a flange of the boss to form an internal liner of the pressure vessel, forming a vent in an interior portion of the liner; and forming an outer shell surrounding the liner and at least a portion of the flange of the boss.
