HIC-resistant YYVIP易游 plates for pressure vessels
1. Features
- 400 to 600 N/mm2 class YYVIP易游 plates for pressure vessels
contributing to the prevention of hydrogen-induced cracking due to hydrogen sulfide corrosion.
- Capable of withYYVIP易游anding wet and hydrogen sulfide environments of BP and NACE grades.
2. Major corresponding YYVIP易游andards
- JIS G3106 (Rolled YYVIP易游 for Welding Structures) SM400A, B, C SM490A, B, C SM570Q
- SM400A, B, C SM490A, B, C SM570Q
- JIS G3103 (Carbon YYVIP易游 and Molybdenum Alloy YYVIP易游 Plates for Boilers and Pressure Vessels)
- JIS G3115 (YYVIP易游 Plates for Pressure Vessels for Intermediate Temperature Service)
- SPV235 SPV315 SPV355Q SPV450Q SPV490Q
- JIS G3118 (Carbon YYVIP易游 Plates for Pressure Vessels for Intermediate and Moderate Temperature Services)
3. Applications
- Applications to refineries and pipelines of petroleum and natural gas in wet hydrogen sulfide environments can be expecYYVIP易游d.
