Dear All,
Greetings of the day.
I know that given group is a Welding group and i am asking query on Painting spec. Kindly forgive me for same.
I am new to painting requirements for a given service. I have referred following spec for a given temperature and C-5M (marine) environmental conditions:
1. CINI manual.
2. Norsok M-501.
3. MIL standard.
4. EIL spec.
5. ISO 12944.
6. NACE SP198.
All are providing different-different painting systems for C-5M (marine) atmosphere. I am very confused due to same and not able to come on a conclusion.
Request all to provide guidelines to be followed in C-5M conditions for following temperature:
| Sr. No. | Metallurgy | Temperature service °C | Surface condition | Shop application | Filed application |
| 1 | CS/LTCS/LAS | (-35) to 125 | Insulated |
|
|
| 2 | CS/LTCS/LAS | Atmosphere to 125 | Insulated |
|
|
| 3 | CS/LTCS/LAS | Atmosphere to 125 | Uninsulated |
|
|
| 4 | CS/LTCS/LAS | 126 to 250 | Insulated |
|
|
| 5 | CS/LTCS/LAS | 126 to 250 | Uninsulated |
|
|
| 6 | CS/LTCS/LAS | 251 to 500 | Insulated |
|
|
| 7 | SS | (-35) to 125 | Insulated |
|
|
| 8 | SS | Atmosphere to 125 | Insulated |
|
|
| 9 | SS | Atmosphere to 125 | Uninsulated |
|
|
| 10 | SS | 126 to 250 | Insulated |
|
|
| 11 | CS/LTCS/LAS/SS | Underground vessel | Underground vessel |
|
|
| 12 | CS/LAS/SS | Atmospheric | Salt water spray area |
|
|
| 13 | CS | Atmospheric | Sea water splash zone |
|
