【考案の詳細な説明】
本考案は、流体輸送管等に用いられる可撓性複
合管の改良に関するものである。[Detailed Description of the Invention] The present invention relates to an improvement of a flexible composite pipe used as a fluid transport pipe or the like.
この種の可撓性複合管は、例えば海底に布設さ

チツクパイプの上に金属線又は金属帯の如き金属
条を巻付けて形成した金属補強層を有する。しか
し、この可撓性複合管は布設時等に繰返し曲げを
受けると、金属条相互が相対的に変位するため金
属条が摩耗し易い欠点があつた。 This type of flexible composite pipe has a metal reinforcing layer formed by wrapping a metal strip such as a metal wire or metal strip around the plastic pipe to prevent damage from the outside when it is laid on the seabed, for example. have However, when this flexible composite pipe is subjected to repeated bending during installation, etc., the metal strips are displaced relative to each other, which causes the metal strips to easily wear out.
本考案の目的は、繰返し曲げを受けても金属条
を摩耗することがない可撓性複合管を提供するこ
とにある。 An object of the present invention is to provide a flexible composite tube whose metal strips do not wear out even when subjected to repeated bending.

の金属線から成つているが、金属帯でもよい。 Embodiments of the present invention will be described with reference to the drawings. FIG. 1 shows a flexible composite pipe 10 according to the present invention, which includes a nylon plastic pipe 12 and an upper part of the plastic pipe. metal strip 1
4 and a metal reinforcing layer 16 formed by closely wrapping the metal reinforcing layer 16 in multiple layers, and a plastic jacket 18 made of polyethylene or the like is provided on the metal reinforcing layer 16. In the illustrated embodiment, the metal strip 14 is comprised of a plurality of metal wires, but it may also be a metal strip.
金属補強層１６の金属条１４は、第２図に示す

いプラスチツクコーテイング層１４ａを有する。
従つて可撓性複合管が繰返し曲げを受け、金属条
１４相互が相対的に変位しても、金属条１４が摩
耗することがない。 As shown in FIG. 2, the metal strip 14 of the metal reinforcing layer 16 has a plastic coating layer 14a made of nylon or the like having good wear resistance on its surface.
Therefore, even if the flexible composite tube is repeatedly bent and the metal strips 14 are displaced relative to each other, the metal strips 14 will not wear out.
ところでプラスチツクコーテイング層１４ａを
下記の材料で構成して、テーパ摩耗試験機で、摩
耗特性を試験した。 By the way, the plastic coating layer 14a was made of the following material, and its abrasion characteristics were tested using a taper abrasion tester.
試験条件は下記の通りである。 The test conditions are as follows.
荷重 1000ｇ
回転速度 70rpm
回転総数 5000回
砥石 CS17
上記条件による摩耗量（cm3）の試験結果は下記
の通りである。 Load: 1000g Rotation speed: 70rpm Total number of rotations: 5000 times Grindstone CS17 The test results for the amount of wear (cm 3 ) under the above conditions are as follows.
ナイロン 0.004
ポリエチレン 0.01
シリコンゴム 0.32
ブチルゴム 0.26
その結果、ゴムは耐摩耗性が悪く、本考案にお

がわかる。 Nylon 0.004 Polyethylene 0.01 Silicone rubber 0.32 Butyl rubber 0.26 As a result, rubber has poor abrasion resistance and is not suitable as a material constituting the plastic coating layer 14a of the present invention, whereas nylon and polyethylene have good abrasion resistance and are suitable for plastic coating. It can be seen that this material is suitable as a material constituting the layer 14a.
本考案によれば、上記のように、金属補強層の
金属条に耐摩耗性の良いプラスチツクコーテイン
グ層が設けられているので可撓性複合管が繰返し
の曲げを受けても金属条が摩耗することがなく、
寿命を長くすることができる実益がある。 According to the present invention, as described above, since a plastic coating layer with good wear resistance is provided on the metal strip of the metal reinforcing layer, the metal strip will wear out even if the flexible composite pipe is subjected to repeated bending. Without a problem,
There are practical benefits that can extend your life.
