Resumen:
This standard specifies the dimensions, design, types, designation, materials and marking of spiral wound gaskets for use with type A flat face or type B raised face flange facings complying with EN 1759-1 for Class designations Class 150, to Class 1500 for nominal sizes DN 15 to DN 600 and for Class designation 2500 up to and including DN 300. The centering rings for the spiral wound gaskets according to this standard are sized for use with imperial bolting. The dimensions of spiral wound gaskets for tongue and groove flange facing types and spigot and recess flange facing types to EN 1759-1 are not included in this standard. The current standard is derived from the ASME standard B16.20. The revision is necessary to align the current standard of 2001 with the recent dimensional changes made to the ASME standard to improve the performance of gaskets. The main changes are concerning the tables.
