Abstract
Description
本願は、2020年4月23日に出願された米国仮特許出願第63/014,392号の利益を主張し、その内容を参照により援用するものとする。
本開示は、概して、流体要素に機械的に取り付けるための流体継手を含む流体システムであって、特に、流体継手および流体要素のうちの少なくとも一方が、二相ステンレス鋼材料を含む、流体システムに関する。
現在のところ、管と継手とは、一般的に溶接によって互いに取り付けられている。しかしながら、このような溶接技術は、互いに溶接することができない材料で管と継手とを製造する能力を妨げているか、または適切に溶接するために高度な技能を必要としている。
以下には、本発明の例示的な実施形態の簡単な概要が提示してある。この概要は、重要な要素を特定するかまたは本発明の範囲を限定することを意図するものではない。
以下は、本願の例示的な実施形態の詳細な説明である。本願のこういった実施形態を前述した図面を参照しながら説明することで、当業者には、記載した方法および/または特定の構造の様々な変更または改良が明らかとなり得る。当該技術分野を発展させてきた本願の教示に依存する全てのこのような変更、改良または変形は、本願の精神および範囲内にあると考えられる。したがって、こういった記載および図面は限定的な意味で考慮すべきではない。なぜならば、当然ながら、本願が図示の実施形態に決して限定されるものではないからである。さらに、特定の術語は、本明細書において便宜的に使用しているにすぎず、限定と解すべきではない。さらに、図面には、同じ要素を指定するにあたり、同じ参照符号が使用してある。
