製品説明
バルブシートの利点
1.高温耐性
強度は800℃まで安定しており、1200℃でも瞬間的に使用できます。
2.耐摩耗性
D UE主Aに分散硬質炭化物相の固有の固有の特性に
CoCr合金マトリックスは 、並外れた耐摩耗性と耐かじり性を備えています。
3. 耐食性
この優れた美しい特性により、この種の材料部品をオイル＆ガス、スラリー、酸性 液体、その他の媒体で使用できます。
4. 生産プロセス
粉末冶金プロセスは、 鋳造部品よりも強度が高く、顆粒構造が優れており、 鋳造欠陥によるトラブル を 回避します。
コバルトクロム合金のバルブボールとシートは油井ポンプの非常に重要な部品であり、常に一緒に表示され、非常に良好に協力します。
バルブボールはコバルトクロム合金20で 作られて おり、コバルトクロム合金シートはコバルトクロム合金3で 作られてい ます。彼らは石油とガスのポンピングプロセスの摩耗と腐食問題に抵抗する良いチームです。
