Reliable Storage Solutions for Oil, Petrochemical & Water Industries

At LITCO, we specialize in the design, fabrication, erection, and maintenance of welded steel storage tanks in full compliance with API 650, the globally recognized standard issued by the American Petroleum Institute (API).

With 30+ years of expertise in Saudi Arabia’s industrial sector, and as leading API 650 tank manufacturers, we provide end-to-end tank solutions for crude oil, refined products, water, and petrochemical storage. Our API 650 storage tank units are engineered for long service life, safety, and environmental compliance, meeting the stringent requirements of Saudi Aramco, SABIC, and international EPC contractors.

The API 650 Standard – Scope & Importance

The API storage tank standard applies to welded carbon steel, austenitic stainless steel, and duplex tanks designed for storing ambient-temperature and low-pressure liquids. These tanks are used for a range of applications, including petroleum products, water, chemicals, and firewater storage.

To ensure structural integrity, the tanks are designed with features such as hydrostatic testing, corrosion allowances, and considerations for seismic and wind loads. Compliance with these standards guarantees safe storage, environmental protection, and long-term reliability.

Materials & Construction

At LITCO, we manufacture storage tanks API that adhere to the highest international benchmarks using quality materials and durable construction methods.

– Plates: ASTM A36, A283, A285, A516 Gr. 60/65/70 depending on design pressure and service.
– Nozzles & Fittings: ASTM A105 / A182, stainless steel (SS304/SS316L) when required.
– Welds: Qualified per ASME IX and AWS D1.1.
– Roof Types: Cone roof, dome roof, floating roof (per API 650 Annex C, D, G).
– Foundations: Ring wall or slab foundations designed per API 650 Appendix B and Saudi Building Code.
– Capacity: From 500 m³ to 100,000+ m³ (standard crude oil and water tanks).

API 620 & API 653 Services

– API 620 tanks: For low-temperature (-325°F) and low-pressure applications, used in LNG, LPG, ammonia, and cryogenic storage applications.

– 653 API: Inspection, repair, alteration, and reconstruction of in-service API 650 storage tanks, including:

  – Floor replacement & bottom repairs
  – Roof structure replacement
  – Shell thickness measurement & evaluation
  – Settlement & foundation inspections
  – Re-rating of existing tanks to extend service life

Quality Assurance & Testing

Each tank, be it API 650 or API 620 tanks, undergoes a rigorous QA/QC process to ensure it meets all safety standards and quality requirements. This thorough inspection guarantees compliance with industry regulations and ensures durability and reliability in every unit.

– Hydrostatic Testing per API 650.
– NDT Inspections: Ultrasonic (UT), Radiographic (RT), Magnetic Particle (MPI), and Dye Penetrant (PT).
– Dimensional Checks with total station surveys for roundness, plumbness, and alignment.
– Material Traceability: Mill Test Certificates (MTCs) for all steel plates.
– Third-Party Inspection: Bureau Veritas, SGS, TUV, or client-nominated agencies.
– ISO 9001:2015 certified quality management system.

Safety & Environmental Compliance

Our commitment to safety and environmental compliance is paramount in every stage of our operations. We adhere to stringent industry standards and regulations to ensure the well-being of our workforce and the protection of the environment.

– Secondary Containment: Bund walls and dikes per Saudi regulations.
– Floating Roof Seals: To minimize VOC emissions.
– Fire Protection: Foam chambers, sprinklers, and NFPA-compliant systems.
– Access & Safety: OSHA-compliant stairs, handrails, platforms, and grounding systems.
