   It all fits together, especially this casing made of Stainless Steel 316L!
   
   Consisting of an upper and a lower part, this casing is assembled to one piece, in which, next to the welding job, the fitting together is of great importance. In the foodbranch this is a must!

   After all surfaces have been machined and finished, this fine piece of fitting craftmanship was ready for transport.

   With a specialized transport service SRI delivered the above shown Muffle to one of it’s customers in Germany. Total length of approx 20 meters and a diameter of 2 meters.
   

   Due to the fact this apparatus needs to handle high temperatures, it ’s completely manufactured of Nicrofer 6025HT (high nickel alloy material suited for these high temperatures.)
   
   SRI is specialized in welding and processing various types of stainless steel and high grade materials. Our own SRI  team of 40 qualified welders are able to process almost every type of material.

7. Perfect Welding Equipment for Special Stainless Steel

   21 January 2022 13:45 Leave a Comment

   As our companyname suggests: Special Stainless Steel.
   And these are exactly the materials we work with and weld into special purpose equipment for various industries. Our knowledge we keep up to date with a broad range of education and classes. Know-how of welding Special Stainless Steel materials is one of the reasons SRI is able to provide our customers the top of the bill apparatus in this branch.

   To be able to maintain providing this high quality apparatus, keeping our welding equipment and tools up-to-date is a must!
   
   Recently, a couple of brand new weldingmachines have been purchased; within our specialism the most modern equipment for welding various types of Special Stainless Steel.

   

   Per example: for welding tube-to-tubesheet on heatexchangers, this orbital weldingmachine has been purchased. The picture above shows this equipment in action, during a repair on a heatexchanger. tube-to-tubesheet in Titanium grade II.
   

   

   

   In addition, SRI purchased 4 modern, mobile GTAW-weldingmachines, incl. cooling units. This equipment allows us to weld according to the strictest quality requirements within various designcodes and customer specifications. This picture shows two of these machines, on their first on-site jobs, for repair of a lower section of a reactor.
