Fertilizers play a crucial role in ensuring food security and promoting sustainable development. In the production of nitrogen-based fertilizers, ammonia serves as the initial step. Of these fertilizers, Urea holds significant importance, with widespread use in both the agricultural sector as a fertilizer and additive for animal feed, as well as in the industrial sector for the production of resins and glues.

At FITTINOX, we specialize in manufacturing fittings, branches, and flanges using high-quality materials such as 25.22.2 – S31050 –– 310MoLN, 31603 UREA GRADE, and 316L MOD UREA ®. We meticulously adhere to the drawings provided by licensed UREA process plant operators, including SAIPEM TB5002, STAMICARBON, UREA CASALE, TOYO, as well as those involved in AMMONIA, NITRIC ACID, MELAMINE, and METHANOL production.

Our products undergo rigorous testing at ISO17025 accredited laboratories, ensuring their ability to withstand the demanding production process. This process involves high temperatures and pressures, resulting in the generation of highly corrosive and hazardous gases.
