ガスケット パッキン Q&A No.12 ジョイントシート注意点

ジョイントシートの使用上の注意点はありますか?

■ジョイントシート、選定時の注意点を説明させて頂きます。  〇低圧フランジ(JIS 2K, 5K 等)には適さない。   →必要な締付面圧が得られない  〇FFフランジでもリング状ガスケットを用いる   →必要な締付面圧が得られない  〇フランジ表面の仕上げ精度  液体 6.3μmRa以下                 ガス 3.2μmRa以下

basic information

■ノンアスジョイントシートで注意すること  〇初期から十分な力で締付ける  〇昇温後、時間が経過してからの増し締めはしない   →ガスケットが熱により硬化し、硬化後の増し締めはガスケットの破断につながる    恐れがある  〇蒸気シールに用いる場合、硬化が起こりやすいので特に注意が必要   →石綿ジョイントシートに比べ、高い締付力が必要であり、寿命も短い
