Presentation Transcript

  1. Preparing Gas Pipeline Weld Seams on Po River • Major river, spanning east to west Italy • Sensitive residential environment; cultivated fields and populated villages • New pipeline development • Weld seam preparation

  2. Preparing Gas Pipeline Weld Seams on Po River Project Details: • 35cm(14in) diameter pipe welded every 10m(33ft) • River-crossing sections 2km(1.25miles) • Total project 18km(11miles) Specifications: • Metal cleaned, then profiled to 50microns(2mils) • SA2.5 / NACE 2 / SP-10 • To “White Blast Cleaning”

  3. Preparing Gas Pipeline Weld Seams on Po River Chose Sponge-Jet based on: • Conventional abrasive - hard to contain; potential water contamination • Sponge Media is easily contained, collected and reused without leaving dust or pollutants in the pipe or air • Used 200HP and 35-P Recycler • Silver 80 Sponge-Media™

  4. Preparing Gas Pipeline Weld Seams on Po River Outcome: • Sponge Media blasting allowed the pipeline to be built adjacent to a residential bridge, reducing the planned pipe length from 38km (23miles) to 18km (11miles) - saving 20km (12.5miles) of pipeline • No contamination to the river or surrounding villages • Reduced staging and transport costs: Sponge Media was reused on site, so that Sponge Media, blasting/recycling equipment, welding equipment, crane, generator and compressor were all on one vehicle
