What is the maximum working pressure for the DIN 11851 Weld End with Nut, Stainless Steel, Type DWS across different DN sizes?

The maximum working pressures for the DIN 11851 Weld End with Nut, Stainless Steel, Type DWS are: - DN10–DN40: up to 40 bar - DN50–DN100: up to 25 bar - DN125–DN150: up to 16 bar

Can the DIN 11851 Weld End with Nut, Stainless Steel, Type DWS be used with different gasket materials to extend its operating temperature range?

Yes. The DIN 11851 Weld End with Nut, Stainless Steel, Type DWS can be used with different gasket materials to extend its operating temperature range. The fitting itself is stainless steel and rated for the pressures listed (up to 40 bar for DN10–DN40, 25 bar for DN50–DN100, 16 bar for DN125–DN150); its usable temperature limits are determined by the gasket selected. By choosing gaskets made from higher‑temperature elastomers (e.g. PTFE, expanded PTFE, graphite, or high‑temperature silicone) you can raise the assembly’s maximum service temperature compared with standard elastomers (EPDM, NBR). Conversely, for very low temperatures select materials rated for cryogenic service. Always verify the chosen gasket’s chemical compatibility, compression set, and pressure/temperature ratings for the specific media and operating conditions, and follow manufacturer recommendations and applicable standards to ensure a safe, leak‑tight connection.
