Industrial Equipment Manufacturing
Industrial equipment manufacturing is another exciting yet challenging area of expertise for Sazvar Sazeh Azarestan.
With a strong focus on the design and fabrication of key and critical components for the country’s industrial projects, we have successfully carried out the manufacturing, transportation, and installation of various equipment—such as the supply of pressure vessels for the utility unit of the Pasargad Qeshm Power Plant project, and the sand filter tanks for the 100,000 m³/day desalination project in Bandar Abbas.

✅ Location: Khuzestan Province, cities of Khorramshahr and Minushahr
✅ Client: Tana Energy Management Company
✅ Scope of Work: Supply, fabrication, painting, and loading at the factory site
About Sand Filters (Pressure Sand Filters)
Sand filters—also known as sand filtration units or pressure sand filters—are among the most commonly used and practical water treatment devices. They are primarily utilized for removing algae, turbidity, discoloration, and suspended particles larger than 50 microns.
The main function of a sand filter is to eliminate coarse suspended particles and significantly reduce water turbidity. As water flows through layers of sand and silica, the suspended solids are trapped, resulting in the initial phase of water purification.
In the construction of horizontal sand filter tanks, the lower third of the tank is separated using a nozzle plate. Segments of these nozzle plates are welded together. Filtration media are layered on top of the nozzle plate, and water droplets pass through precision-drilled holes (as seen in the accompanying images), eventually dripping into the bottom third of the tank for collection.
Our dedicated team at Sazvar Sazeh Azarestan carried out sandblasting, cleaning, painting, and welding operations in an extremely confined space, with a maximum internal height of only 70 centimeters.
You can now view the photo report of the desalination tank construction project in the cities of Khorramshahr and Minushahr, with a total capacity of ۱۲,۵۰۰ cubic meters—one of the key equipment-based projects delivered by Sazvar Sazeh Azarestan.

Fixed Silos Inside the Melting & Casting Hall – Material Handling System
Sepid Foolad Kavir Steel Production Complex
Project Details:
✅ Total Structure Weight: 632 tons
✅ Location: Aran & Bidgol County, Isfahan Province
✅ Client: Sepid Foolad Kavir Steel Manufacturing Company
✅ Scope of Work: Supply, fabrication, painting, transportation, and installation
In the melting hall, the two primary raw materials used are scrap iron and sponge iron. In addition, fluxes, slag formers, lubricants, and alloying agents are delivered from bulk material silos via conveyor belts to daily charge silos.
This project features ۴۸ hoppers installed along axis A-B, which supply essential materials to the melting ladles. These hoppers play a vital role in enhancing the performance and quality of the melting process.
