Bilad Al Duha

Bilad Al-Duha is your one-stop resource for all your Tank fabrication needs. It includes plate material procurements as per the code requirement.

Bilad Al-Duha owns a mechanical fabrication shop with all the required equipment for plate cutting, rolling, beveling and welding.

We build tanks according to API 650, API 620 and API 12D standards. API has created standards for the design, fabrication and erection of above ground welded steel storage tanks. API utilizes three standards for field erected tanks : API 650, API 620 and API 12D. We specialize in building to these API standards.

API 650 tanks

The most common standard used is API 650. API 650 tanks are commonly used for oil, gasoline, chemical and produced water storage. You will find these tanks located all around the world in refineries, terminals, pipelines and production facilities. The API 650 standard governs how tanks are designed, processed, welded, inspected and installed.

API 620 tanks

API 620 is a design standard which governs the design and construction of large welded steel low pressure storage tanks. API 620 storage tanks operate at 250°F or less with an operating pressure more than 2 ½ lbf⁄in² and less than 15 lbf⁄in² gauge.

API 12D tanks

API 12D is a specification for Field Welded Tanks for Storage of Production Liquids. It is the least known of the three standards.

This standard is to field erected tanks as API 12F is to shop built tanks. API 12D predetermined tank dimensions and storage capacities, along with accessories and testing requirements. By creating fixed sizes and requirements, the API 12D has eliminated the need for further engineering, effectively reducing the cost of the tanks.
