Line pipes for gas and flammable media

Salzgitter Mannesmann Stahlhandel Sp. z o.o. offers:

  • HFI pipes with longitudinal seam, induction welded with high frequency power (with diameter range
    from DN100 – DN600, wall thickness up to 25,4mm),
  • SAWL pipes with longitudinal seam, submerged arc welded (with diameter range from DN500 –
    DN1500, wall thickness up to 40,0mm),
  •  SAWH pipes with spiral seam (with diameter range from DN600 – DN1600, wall thickness up to
    25,4mm),

  • three-layer polypropylene insulation – 3LPP acc. to DIN 30678,
  • polyurethane insulation acc. to PN-EN ISO 12944; PN-EN 15655:2009,
  • polyamide (VESTAMID®),
  • fibrous cement mortar suitable for drill pipes HDD,
  • fiberglass resin composite (additional protection of external coats),
  • and internal paint coatings.
