"Resa Madab Sazan Zhanub" company, by establishing operational units near the industrial hubs of Tehran, produces the most specialized refinery equipment including heat exchangers, pressure vessels and distillation towers according to ASME and TEMA standards. Unlike commercial companies, relying on reverse engineering knowledge and certified materials, this group has solved the challenge of supplying complex industrial parts in oil and gas projects. The main focus of our technical team in Tehran is to optimize the thermal efficiency of the equipment to reduce the long-term operating costs of refineries.
Why choosing a domestic manufacturer of petrochemical equipment is a necessity?
In the current market conditions, supplying equipment from domestic manufacturers is no longer a choice, but a solution for the survival of production lines. According to our field investigations in recent projects in Tehran, the import of auxiliary parts creates a big risk during project delivery due to sanctions and exchange rate changes.
When it comes to rotating equipment or special heat exchangers, the geographical distance of the manufacturer to the installation site is of critical importance. By deploying support teams in Tehran, Rasa Madabat has minimized this distance so that after-sales services and unexpected troubleshooting can be done without wasting time.
Technical standards in the construction of heat exchangers
In practice, it has been observed that many heat exchangers leak or clog prematurely due to the lack of accurate calculation of "thermal stresses" at the time of construction. We at Rasa Makwad Sazan Zaubun use pre-production software design methodology. Each device, before entering the welding stage, is subjected to software calculations so that variables such as operating pressure, fluid temperature and material corrosion rate can be fully predicted.
Challenges of supplying material and a solution to express the converter
One of the biggest challenges for petrochemical equipment manufacturers in Iran is the lack of standard materials (ASTM) in the open market. In order to overcome this challenge, Rasa Kadab Sazazan South has implemented a direct supply system from the top alloy steel producers. We test the quality of each steel shipment before using it in the project in Tehran's reliable metallurgical laboratories. This obsession in choosing sheet and tube guarantees the longevity of the device in corrosive operational conditions.
A look into the future; Energy optimization in petrochemical equipment
Our next goal in future projects is to improve the heat transfer coefficient in exchangers by changing the geometry of tube bundles. Reducing energy consumption in refineries is possible through these minor changes in equipment design. Our company in Tehran is currently implementing a new generation of converters that offer the highest output for refining processes with the lowest amount of fouling.
