Description
圧力容器は概して、例えば、水素、酸素、天然ガス、窒素、プロパン、メタン、及び他の燃料といった様々な流体を、圧力下で収容するために使用される。圧力容器は通常、いかなるサイズ又は構成をもとることができる。これらの容器は、例えば、重量が小さい若しくは大きいことがあり得、単回使用(例えば、使い捨て)や再使用が可能であり得、高圧下(例えば50psiよりも高い)や低圧下(例えば50psi未満)に置かれ得、又は、流体を高温若しくは極低温において貯蔵するために使用され得る。
1つの態様において、流体を保持するための圧力容器が開示される。この容器は、貯槽と、当該貯槽の外側表面上に配置されたコーティングと、を含む。当該貯槽は、流体を保持するための空隙を規定し、当該貯槽の外側表面は、第1の視覚的特徴を含む。当該コーティングは、インジケータ層、外側層、及び第1の中間層を含む。当該インジケータ層は、当該外側表面上に配置され、当該インジケータ層は、第1の視覚的特徴と視覚的に対照をなす第2の視覚的特徴を含む。当該外側層は、インジケータ層の上方に配置され、当該外側層は、第2の視覚的特徴と視覚的に対照をなす第3の視覚的特徴を含む。当該第1の中間層は、当該インジケータ層と当該外側層との間に位置付けられ、当該第1の中間層は、視覚的に透明又は半透明である。
1. 流体を保持するための圧力容器であって、
流体を保持するための空隙を規定する貯槽であって、当該貯槽の外側表面が、第1の視覚的特徴を含む、貯槽と、
前記外側表面上に配置されたコーティングと、

11. 前記インジケータ層、前記外側層、前記第1の中間層、又は前記第2の中間層の少なくとも1つが、折り畳み式フォームを含む、項目10に記載のコーティング。
14. 前記第1の中間層が、前記インジケータ層及び前記外側層の合計の厚さよりも厚い、項目9〜13のいずれかに記載のコーティング。
16. 前記第1の視覚的特徴、前記第2の視覚的特徴、及び前記第3の視覚的特徴の少なくとも1つが、色を含む、項目9〜15のいずれかに記載のコーティング。
本開示は、コーティングが損傷を受けたという視覚的標識を提供する、圧力容器のための保護性多層の種々の実施形態を説明する。加えて、このコーティングは、当該損傷により、容器が使用には不適切であることを判断するには至っていない場合、オペレータがこの容器を引き続き運用し得るように、損傷の深刻度についての視覚的標識を提供する。オペレータは、容器に対する損傷が、当該容器の効果的使用に障害を生じさせている場合、この容器を運用から外し得る。擦傷、掻き傷、又は穴といった損傷は、多層コーティングの少なくとも1つの内側層を露出させ、この少なくとも1つの内側層が、損傷の深刻度についての視覚的インジケータを提供する。例示的な実施形態において、視覚的インジケータは、例えば、対照色、異なる反射率特性、又は異なる屈折特性を含めた、コーティングの層間において対照をなす視覚的特徴によるものであってもよい。加えて、コーティングの例示的な一実施形態は、例えば摩耗及び衝撃といった損傷から圧力容器を保護するように作用する。
