Aliedad is one of the specialized companies in the region as steel tanks manufacturers. We design to (API 650), install and fabricate all types of steel welded or bolted tanks that serve the petrochemical, chemical, pharmaceutical, water and wastewater applications.

Aliedad design and fabricate custom storage tanks with wide variety for liquids e.g. crude oil, diesel, or kerosene, raw water, chlorinated water and wastewater with capacities ranging from 1000 m3 up to 20 000 m3. Aliedad has the technology to deliver sandblasted, coated and tested tanks according to international standards.

Our staff of engineers in the design department have the ability to design all types of steel tanks, fully planned, and detailed complete with shop drawings and deliver these shop drawings for fabrications. After obtaining client approval prior to fabrication.

Tanks are different in design, depending on the type of stored fluid and the environment of tank site, we provide all sorts of roof types, such as:

- Supported cone roof: which is formed to approximate the surface of a right cone that is supported by either rafters on girders and columns or rafters on trusses with or without columns.
- Self-supporting cone roof: which is a roof formed to approximate the surface of a right cone supported only at the periphery. i.e. on the tank shell.
- Self-supporting dome roof: which is a roof formed to approximate a hemi-spherical surface supported only at the periphery.
- Self-supporting umbrella roof: which is a modified dome roof so formed that any horizontal section is regular polygon with as many sides as there are roof plates and supported on the periphery.

Tanks are made out of steel plates. At Aliedad we select the materials carefully in accordance to standards such as: ASTM, ISO, DIN. Our welders are tested; certified. Classified welders are nominated on each type of welding.

Ensuring job excellence is not an option; quality control staff guarantee the best design and fabrication for the tanks

For post tank installation on sites, we carry out all the tests required by the API code to test the structure before starting the sand blasting and coating works.
Some of these tests are:

- Straightness
- Curvatures
- Plumpness
- X- rays (radiographs)
- Vacuum testing
- Dimensional check
- Peaking
- Magnetic particle method
- Liquid penetration method

Not all steel tanks are alike; therefore we provide full solution for the tanks such as:

- Inlet system with its piping of different diameters and valves.
- Outlet system with its piping of different diameters and valves
- Recycle system
- Drain off system
- Flame arrestors
- Level indicators
- Temperature gauges
- Vents
- Fire fighting system
- Floating suction
- Spiral stairway
- Roof hand rail
- Cathodic protection system
- Lightning system
- Earthing system
- Control and instrumentation systems
- Safety system
