1. Project Titanium.

   10 December 2024 11:40 Leave a Comment

   In good cooperation, sitting between customer and suppliers, SRI managed this specialist project by the book. From the start, advising our client, up untill the finalisation of installing the column on our client’s site, SRI supervised this complete project.

   

   Engineering this huge column is a precise work:
   
   With a diameter (incl. platforms) of 4,5m and a length of 20m, plus various connecting points,  this column had to fit right in!

   Cladding the innerwall with Titanium is a masterpiece:

   The column, entirely made of carbonsteel, had to be clad on the productside with a layer of Ti Gr.1, to which high requirements are demanded. By the method of explosion cladding, we were able to achieve great results! Also welding the Titanium cladding itself demanded high requirements: by an automatic weldingprocess, for which we had to set the parameters very accurately.

   

   

   After succesfully withstanding the helium-/pressure tests, this freshly cladded column was ready for special transportation. With thanks to our reliable suppliers and a professional carrier, this project is delivered exacly on time for our client’s TurnAround!

   Once on location, SRI’s team of service technicians were set and ready to handle the column on-site. First demounting the old column, then installing the new one and finalising this project by connecting the column to it’s pipesystem.
   
   Many thanks to all participants and let’s head to a next project!

   

2. Another piece of SRI craftmanship!

   After being manufactured at SRI and coated at a specialist’s facility, this Duplex Column is ready for installation on-site. A spectacular view from the ground!

   The specifications:
   Material: Duplex 1.4462, thickness bodyplate 12mm and heads 15mm
   Total length: 14.500mm
   Widest diameter: 3.200mm
   Weight: 16,5 Tons
   
   Designed conform EN13445, incl. PED module H1. In addition to the customer’s spec.’s, nozzleloads have been calculated and applied in this design.
   

   Throughout all fases of this project, thank you SRI colleagues!

   

3. Separator ready for transport

   17 June 2022 14:39 Leave a Comment

   This last, and at the same time largest, separator out of a project of nine columns, separators and pressure vessels, is ready for transport.
   
   Measuring 6 meters in length and (incl. dome) 3.5 meters in height, the vessel sits on a low loader for transport.
   
   All apparatus in this project were:
   – by SRI, in-house fully engineered, incl. integrated clientspec.’s
   – manufactured of Alloy 316L material (wall thicknesses varying from 8 to 25 mm)
   – manufactured conform designcode EN13445 / PED module H1
   
   All of SRI are proud of (again) a successful project!

   

4. 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.

5. SRI welcomes 13 students from the Lauwers College for a shoptour!

   3 December 2021 14:51 Leave a Comment

   Last month 13 apprentice technicians from the Lauwers College Kollum visited SRI Speciaal Roestvrijstaal Industrie BV, for a day of education in the field of engineering and manufacturing of special purpose high grade apparatus. With great passion SRI colleagues presented the various specialisms within SRI BV.
   
   With refreshments in the canteen, the day was concluded with a Q&A session and a review of a successful day.
   
   SRI BV takes great pride in receiving this opportunity from Lauwers College Kollum and also likes to thank the volunteering colleagues for their enthusiasm guiding the visiting students around the SRI workfloor.
