Subject: [MW:5065] FIttings P235GH & P265GH material for -10 deg C ?
Hello all,
The carbon steel Pipe ( EN 10216 & EN10216 - grade P325GH & P265GH ) & flanges ( EN10222- P245GH) are defined till -10 deg C.
but for Fittings, grade P235GH and P265GH material, are defined are defined only upto Minimum temp. of 0 deg C as per EN10253 table 9.
Is it allowed to use these fittings materials for service at -10 deg C ? if yes then what additional we must take into consideration.
or do we have to go for low temperature material of P355N or P335NH material grade ?
waiting for your replies
Kind regards
Rahul
