We ensure a regular heartbeat

SBN sets the pace with advanced skills and technologies to give customers an edge. Increased production speeds and significantly reduced plant throughput times ensure maximum productivity. Top quality high-pressure equipment and seamless integration with existing systems reduces project risks and provides long-term investment security. The goal for the latest generation of critical process equipment for tomorrow’s urea and ammonia plants: ensuring a regular heartbeat.

The Safurex® and Stamicarbon connection

Having pioneered the extensive use of Safurex®, Christof Group’s specialist and strategic partner of Stamicarbon excels with key material knowledge and unmatched welding skills. In 2019, the first high-pressure stripper was fabricated out of the brand new Safurex® Star and Safurex® Degree materials. High-pressure equipment made with these materials is extremely durable and key to achieving an optimal performance and a maximum lifespan in urea plants.

We repair the “unrepairable”

The situation was critical, the solution creative. In 2016, the unique repair of a pool condenser tubesheet severely damaged by flow-accelerated corrosion not only averted the threat of a significant loss of production in a urea plant, it also set new standards for mastering such highly delicate repairs. In tandem with Stamicarbon, SBN devised a unique game plan to temporarily restore full operation to the client’s plant in China.
