Machine Sazi Arak Co. (MSA), the first and the biggest designer and manufacturer of steam boilers and hot water boilers in Iran and the Middle East, with more than 40 years of dazzling experience and enjoying the services of more than 2500 skilled work force, modern equipment and drawing on the findings of its Training Center and Industrial Research has always been trying its best to manufacture high quality products in line with the latest technological advances. Our products have so far found their way to the domestic markets and different markets abroad.
Radiography, ultrasonic and penetrating liquid tests are performed under the supervision of quality control (QC) inspectors on the welding lines. The stress relieving operations of the boilers are carried out in 600±20 conditions resulting in the uniformity of the microscopic structure in pressure parts and the elimination of the remaining stresses of different processes such as rolling, fabrication and welding. Hydrostatic test is done as per BS2790 standard and 1 .5 times design pressure after tubing. In final step, the burner will be tested about 24 hours. The quality and standard certificates are issued for each boiler after checking all controllers and indicators.
All the designs used in this factory have been approved by TUV Co. (Austria).
