Ein Überlappungsflansch (LJF-Flansch) wird auch Lockerflansch genannt, er hat zwei Komponenten, ein Stummelende und einen losen Stützflansch, Stub-Ende ist stumpf an das Rohr geschweißt und Stützflansche bewegen sich frei über das Rohr, LJF-Flansch wird besonders für häufigen Abbau oder schwer einstellbare Rohrverbindung verwendet.
Unsere Flansche, Rohrbögen und Armaturen werden mit fortschrittlicher CNC-Ausrüstung und bewährten Prozessen hergestellt und liefern genaue Abmessungen, stabile Dichtungsleistung und zuverlässige Installation für anspruchsvolle industrielle Anwendungen.
