Welcome to the API Subcommittee on Aboveground Storage Tanks (SCAST) web page. SCAST provides an important service to the refining, marketing, pipeline and petrochemical industry by developing recommended practices and construction, inspection and repair standards for aboveground storage tanks. In addition to the petroleum industry, API's tank standards are also used in the pulp and paper, utilities, food processing, fertilizer, and other process-related industries. SCAST's portfolio of standards includes:
- Std 620 - Design and Construction of Large, Welded, Low-Pressure Storage Tanks
- Std 625 - Tank Systems for Refrigerated Liquefied Gas Storage
- Std 650 - Welded Tanks for Oil Storage
- RP 651 - Cathodic Protection of Aboveground Storage Tanks
- RP 652 - Lining of Aboveground Petroleum Storage Tank Bottoms
- Std 653 - Tank Inspection, Repair, Alteration, and Reconstruction
- Spec 12B - Specification for Bolted Tanks for Storage of Production Liquids
- Spec 12D - Specification for Field Welded Tanks for Storage of Production Liquids
- Spec 12F - Specification for Shop Welded Tanks for Storage of Production Liquids
- Spec 12P - Specification for Fiberglass Reinforced Plastic Tanks
- RP 12R1 - RP for Setting, Maintenance, Inspection, Operation, and Repair of Tanks in Production Service
- Std 2015 - Requirements for Safe Entry and Cleaning of Petroleum Storage Tanks
- RP 2016 - Guidelines and Procedures for Entering and Cleaning Petroleum Storage Tanks
- Publ 2026 - Safe Access/Egress Involving Floating Roofs of Storage Tanks in Petroleum Service (SCAST document as of 2013)
- RP 2027 - Ignition Hazards and Safe Work Practices for Abrasive Blasting in Petroleum Service (SCAST document as of 2013)
- RP 2207 - Preparing Tank Bottoms for Hot Work (SCAST document as of 2013)
- Std 2510 - Design and Construction of LPG Installations (SCAST document as of 2013)
- Std 2610 - Design, Construction Operation, Maintenance, and Inspection of Terminal and Tank Facilities
These standards draw from a synergy of a high level of technical expertise and a long history of experience. The tank standards benefit owner/operators by providing the perspective and experience of other companies. Small companies gain expertise that would not be practically available otherwise. All companies benefit from proactively following industry standards developed using API's consensus process.
