Tank Fabrication Suppliers, Saudi Arabia

Tank fabrication encompasses the design, manufacture, and erection of atmospheric and low-pressure storage tanks for crude oil, refined products, water, chemicals, and LNG per API 650, API 620, and AWWA D100 standards. GCC tank fabricators construct welded steel tanks from small process tanks to massive crude oil storage tanks exceeding 100,000 cubic meters. The region's oil storage requirements, strategic reserves, and expanding petrochemical infrastructure sustain continuous demand for tank construction services.

Tank fabrication involves the manufacture and erection of atmospheric and low-pressure storage tanks across the UAE and Saudi Arabia for storing crude oil, refined petroleum products, chemicals, water, and liquefied gases. Design and construction follow API 650 for atmospheric welded tanks, API 620 for low-pressure tanks, and AWWA D100 for potable water storage.

Fabrication methods include shop-built tanks (transported as modules or components) and field-erected tanks constructed on-site using plate-by-plate or jacking methods. Tank types include fixed-roof, external floating roof, internal floating roof, and double-wall configurations. Materials are predominantly carbon steel (ASTM A36, A283, A516), with stainless steel and special linings for chemical and food-grade storage.

The GCC's vast oil storage capacity, strategic petroleum reserves, and expanding petrochemical sector drive sustained demand for tank fabrication. Major tank farm developments in Fujairah, Ras Al Khaimah, Jubail, Yanbu, and Jazan require experienced contractors capable of constructing tanks from 500 cubic meters to over 120,000 cubic meters. Procurement managers should evaluate tank fabricators based on API certifications, track record with specific tank types and sizes, field erection capabilities, NDT and testing resources, and compliance with client-specific standards from Saudi Aramco, ADNOC, or Vopak.

Frequently Asked Questions — Tank Fabrication

What is the difference between API 650 and API 620 storage tanks?

API 650 covers atmospheric storage tanks with internal pressures at or near atmospheric (up to 2.5 psi). API 620 covers larger and more complex tanks designed for internal pressures up to 15 psi, including refrigerated tanks for LNG and LPG storage.

What are the main methods of tank erection in the GCC?

The conventional method builds the tank from bottom to top using plate courses. The jacking method (jack-up) builds from the top down, raising completed courses with hydraulic jacks. The jacking method is faster and reduces the need for scaffolding, making it preferred for large GCC tank farm projects.

What inspection and testing is required for storage tank fabrication?

Weld inspection includes visual, radiographic (RT), ultrasonic (UT), magnetic particle (MPI), and vacuum box testing. Foundation settlement monitoring, hydrostatic testing (filling with water to design level), and roof-to-shell joint testing are mandatory before commissioning. All testing must comply with API 650 Chapter 7 or the applicable standard.
