SCHWERLL High-pressure clamp flange for large-diameter pressure pipelines, using an insert-mounted sealing element and hard-seal arrangement to simplify seal replacement. The official product page publishes nominal diameter and working-pressure maxima, while the supplied size and pressure configuration must be confirmed for the specific project.
SCHWERLL plug‑plate flanges are specifically designed for large‑diameter pressure pipelines. Addressing the challenges associated with installing such flanges—such as difficult installation, limited clearance height, and alignment issues—as well as the logistical difficulties of seal replacement, SCHWERLL’s plug‑plate flange features a separate sealing element mounted on an independent insert. The hard‑seal system installed on both sides of this insert effectively compensates for certain installation inaccuracies and simplifies seal‑replacement operations. SCHWERLL’s official High-pressure clamp flange product page states nominal diameters up to DN 15,000 mm and working pressures up to 100 MPa. These are independent published page-level maxima. The available evidence does not map either maximum to SKU SCH-1043 or establish that both maxima apply simultaneously to one supplied configuration. The supplied nominal diameter and working pressure must be confirmed in the approved project documentation.
