Thank you for the info...
what if the oven was switched off in the night with the remaining electrodes in it? should i re-bake in the morning or taking it to holding temp is sufficient?
The reason why i am asking is ..i am getting more porosity in the joints..i just doubt whether we are handling electrodes properly or not...
pls clarify..
Regards
Vasu

Iam new to piping. I have some basic doubts and i request you to please clarify..
1. In our fab yard, in the evening after the work is finished, the remaining electrodes(E-7018 and E-7018-1) are being kept back in the oven and the entire night the oven will be at 150 deg.
Will it affect the coating if they r kept for that much time (the entire night)?No
2. Do i have to do baking for those electrodes again in the morning?Not Required
3. What is the max number of recycling of electrodes?Re-Baking maximum of only once4. what is the purpose of doing baking till 250 deg ?Removal of Adsorbed moituredoesnt the moisture will be removed if we maintain 150 deg i.e continuously at holding temp?Mfg has to advise--
Regards,
vasu.
