    摘要: A hose for conveying a refrigerant, having an inner surface layer that includes a thermoplastic resin composition with a sea-island structure or a thermoplastic resin, an outer surface layer that includes a thermoplastic resin composition having a sea-island structure, and a reinforcing layer. An oxygen permeability coefficient at a temperature of 21° C. and a relative humidity of 50% of the thermoplastic resin composition or the thermoplastic resin of the inner surface layer is 0.05 cm3·mm/(m2·day·mmHg) or less. A water vapor permeability coefficient at a temperature of 60° C. and a relative humidity of 100% of the thermoplastic resin composition of the outer surface layer being is 10.0 g·mm/(m2·24 h) or less. The reinforcing layer includes an organic fiber with an inclination angle of 49° or more and 61° or less.

    摘要: A method and apparatus for storing at least one fluid, and a flexible fluid storage pipe are disclosed. The method comprises: via a production device, providing a desired quantity of at least one fluid to be stored; transporting the quantity of fluid from the production device into at least one flexible pipe member via at least one fluid import region of the flexible pipe member, the flexible pipe member being windable around a spool element and comprising an inner fluid retaining layer that defines a bore region of the flexible pipe member, an outer sheath disposed over and coaxial with the inner fluid retaining layer and at least one composite reinforcement layer comprising helically wound fibre reinforced thermoplastic tapes that is disposed between the inner fluid retaining layer and the outer sheath; closing the fluid import region of the flexible pipe member to thereby retain the quantity of fluid in the bore region of the flexible pipe member; and storing the quantity of fluid at a first pressure in the bore region.

    摘要: A reinforced thermoplastic pipe (RTP), RTP body, and a method of providing RTP body are disclosed. The method of providing RTP body for storage and/or transportation of a fluid, comprises providing a first pipe body layer; providing a further pipe body layer coaxial with the first pipe body layer; providing a plurality of helically wound wire elements disposed between the first pipe body layer and the further pipe body layer; heating surrounding precursor thermoplastic material via Joule heating of the wire elements thereby providing viscous state thermoplastic polymer at least one of a first interface location between the first pipe body layer and the further pipe body layer; and subsequently cooling the viscous state thermoplastic polymer for joint consolidation thereby consolidating RTP body over at least a portion of a whole length of the RTP body.

    摘要: The disclosure provides a high-pressure hose of a pressure washer and a pressure washer. The high-pressure hose of a pressure washer includes an inner hose, an outer hose and an interlayer. The inner hose defines a fluid flow passage. The outer hose covers the inner hose. And the interlayer is arranged between the inner hose and the outer hose. The interlayer at least includes a braided layer. The braided layer is provided with by a latticework of interwoven yarn to be a cylindrical structure, and covers an outer wall of the inner hose. The high-pressure hose of the disclosure has both good pressure-bearing performance and good softness, which improves a user's experience.
