PRE-INSULATED PIPES AND FITTINGS

PE-ST-PU-SPIRO AND ST-PU-SPIRO

PE-ST-PU-SPIRO and ST-PU-SPIRO

PRE-INSULATED PIPES AND FITTINGS

for use in mining

MATERIAL polyethylene liner, steel pipe, polyurethane foam, flame retardant casing pipe made of steel strip

APPLICATION in rooms and underground workings classified as “a”, “b”, “c” of methane explosion hazard and “A” or “B” class of coal dust explosion hazard.

RANGE from DN42.4 to DN610 mm – for ST-PU-SPIRO pipes from DN88.9 to DN610 mm – for PE-ST-PU-SPIRO pipes pressure up to PN 160

PE-ST-PU-SPIRO and ST-PU-SPIRO pipes are intended for the construction of air-conditioning and technological installations.

APPLICATIONS

PE-ST-PU-SPIRO and ST-PU-SPIRO pipes are intended for the construction of air-conditioning and technological installations, i.e:

  • water,
  • ice water, brine,
  • other water solutions (acceptable only for PE-ST-PU-SPIRO pipes)
  • chemically aggressive liquids (allowed only for PE-ST-PU-SPIRO pipes)

APPLICATION PARAMETERS:

  • pressure up to PN 160
  • temperature from -20˚C to + 60˚C (PE-ST-PUSPIRO) and from -20˚C to + 130˚C (ST-PU-SPIRO)

PIPE JOINING METHODS:

  • Victaulic System couplings
  • flange connections
  • welding

ADVANTAGES OF PE-ST-PU-SPIRO AND PE-ST-PUSPIRO PIPES:

  • good thermal insulation (worse than in the case of pipes with a polyethylene jacket)
    the possibility of isolating the connection

ADDITIONAL ADVANTAGES OF PE-ST-PU-SPIRO PIPES:

  • high smoothness of the inner surface of the polyethylene pipe reduces flow resistance
  • high abrasion resistance under the action of liquids containing solid suspensions
  • high chemical resistance to most substances present in the transported media
  • no overgrowth with sediment – hydraulic parameters unchanged over time
  • no corrosion of the inner liner
  • extended service life in relation to steel pipes
