BSP pipe fittings pressure temperature ISO 8434 6

Date:Jun 11, 2019

BSP pipe fittings pressure temperature is also specified by ISO 8434 6, it rated pressures for 60° cone connector ends.


60° cone connectors in conformance with this part of ISO 8434 made of carbon steel shall meet or exceed without leakage the requirements from a vacuum of 6,5 kPa (0,065 bar) absolute pressure to the rated pressures given in Table 1 when used at temperatures between –40 °C and +120 °C. For stud end connectors, the upper

limit shall be the lower of the rated pressure given in Table 1 and the rated pressure for the relevant stud end, i.e., ISO 1179-2, ISO 1179-3 or ISO 6149-3.
