ACT-100-U® Specification for External Corrosion Protection of Composite Steel USTs (F961)
The ACT-100-U® Specification for External Corrosion Protection of Composite Steel Underground Storage Tanks (F961) covers a method of underground exterior corrosion control for steel tanks. The method, termed cladded composite steel underground storage tank (ACT-100-U®), combines two basic corrosion control approaches.
- General Requirements
- Electrical Isolation
- Tightness Testing
- Application of Cladding
It is the intent of this specification to incorporate the technical gains and achievements from previous specifications and standards, while enabling new forms of proven composite steel tank technology to be adopted. The primary purpose of this specification is to establish composite steel tank (ACT-100-U®) production procedures which are fully supported by quality assurance measures and proper installation requirements.
