C70600 Copper Nickel Flange EEMUA 145 Manufacturer
C70600 Weld neck flanges, C70600 Slip on flanges
EEMUA 145 : 1986 is the standard for COPPER NICKEL ALLOY PIPING FOR OFFSHORE APPLICATIONS – SPECIFICATION – FLANGES COMPOSITE AND SOLID
Now EEMUA 234 is a new publication that combines and updates the content of EEMUA 144, 145 and 146, which have now been withdrawn. Bringing everything together into one publication means the information is more accessible to the user.
