Fuel System SCR Tanks

Following their initial use in commercial vehicles, selective catalytic reduction (SCR) systems are being increasingly used in passenger vehicles with diesel engines. The process of selective catalytic reduction serves to convert nitrogen oxides in exhaust gas into nitrogen and water without unwanted by-products using a urea solution.


  • Tanks and fuel pipe unions: palletized lines or transfer lines with robot between stations. Stationary and mobile cutting and welding units, or robotised.
  • SCR tanks – welding of components:  welding machine with stationary welding unit or with interchangeable unit frames. Robotic loading/unloading of half-casings and components available as an optional.
  • SCR tank – half-casings welding: hot-blade welding machine in 4 standard sizes, with electrical motion. Feeding by turntable and/or robotised available as an optional.


  • Standard drilling unit without waste, with adjustable drilling diameter and cycle objectification.
  • Manufacturing and punching unit for gasoline pump seating.
  • Standard welding unit with separate temperature control for component and tank, tank geometrical tolerance offset, control of forces, times and welding depth specifically designed for multi-layer tanks. Storage of all data in machine.
  • Standard pump tightening unit, with torque and angle control.
  • Immersion seal test to check for leaks in virtual vision.


  • Blow molded or injected tanks can be welded, both PP and PEHD. It is possible to take up considerable differences on geometrical and dimensional tolerances without jeopardising mechanical strength and leak-proof seal of the welding.
  • All the welding data (times, temperatures, pressures and strokes) are stored and associated to the QR code and to the traceability system data.
