Pressure reductions for cutting ring screw connections

Product catalog summary
Technical Information Overview
This document provides technical information regarding pressure reductions for cutting ring screw connections made of rustproof stainless steel 1.4571. It emphasizes the importance of proper assembly of the screw connections and pipe conduits to achieve the maximum nominal pressure values listed in the catalogue under PN.
Pressure Reductions Based on Temperature
As operating temperatures increase, corresponding pressure reductions must be considered. This is crucial when using different materials, where the lowest nominal pressure is used for calculations. The document provides a table with specific pressure reduction percentages based on temperature ranges:
  • -60° to +20°C: No reduction
  • +50°C: 4.5% reduction
  • +100°C: 11.0% reduction
  • +200°C: 20.0% reduction
  • +300°C: 29.0% reduction
  • +400°C: 33.0% reduction

ARMATUREN-ARNDT | Technische Informationen Druckabschläge für Schneidringverschraubungen Pressure reductions for cutting ring screw connections Die im Katalog unter PN genannten Werte sind Angaben für den maximalen Nenndruck und beziehen sich auf Schneidringverschraubungen aus rostfreiem Edelstahl 1.4571 und setzen eine ordnungsgemäße Montage der Verschraubung und der Rohrleitungen voraus. Bei steigenden Betriebstemperaturen sind entsprechende Druckabschläge zu berücksichtigen. Dies gilt auch bei der Verwendung unterschiedlicher Werkstoffe, wo der jeweils niedrigste Nenndruck die Berechnungsgrundlage bildet. Die entsprechenden Werte entnehmen sie bitte der nachstehenden Tabelle. The values listed in the catalogue under PN are data for maximum nominal pressure and refer to cutting ring screw connections (couplings) made of rustproof stainless steel 1.4571 and presuppose assembly of the screw connection (couplings) and the pipe conduits according to regulations. In the event of increasing operating temperatures corresponding pressure reductions should be considered. This also applies during the use of differing materials, where the respective lowest nominal pressure forms the basis for calculation. For the corresponding values please consult the table below.
