  • Submarine crossings over rivers
  • Outfall and intake pipelines for industrial cooling and effluent discharge

They are also extensively used in agriculture for irrigation and pressurised sewer systems. WEIDA complements its pipe solutions with a full range of fittings and welding services for reliable system performance.

  • Available in a variety of sizes, ranging from Ø20mm (OD) to Ø630mm (OD)
  • Nominal pressure ratings from PN 6.3 to PN 20
  • Comprehensive selection of fittings, including:
  1. Fabricated HDPE fittings
  2. Compression fittings
  3. Electrofusion fittings
