Basic material

Stainless steel

S235JR (ST37-2) plastic-coated steel serves as a basic material, Rilsan-coated, approved for drinking water. Conforms to KTW requirements [official German recommendation concerning the levels of polymers in drinking water] as recommended by the German Federal Department of Health.

S235JR (ST37-2) galvanized steel serves as a basic material, only suitable to a limited extent for drinking water, to be used for flange connections only.

Properties and suitability

Stainless steel of various qualities depending on groundwater condition and temperature

M No. 1.4301 (X5CrNi18-10), AISI 304 This type of steel is resistant to water and slightly polluted waste water as well as weak organic and inorganic acids. Generally, it is resistant to a pH value up to approx. 4.5 in aggressive substances low in chloride.

M No. 1.4541 (X6CrNiTi18-10), AISI 351 This type of steel has excellent resistance properties to a variety of aggressive media. Furthermore, this material is characterised by good ductility.

M No. 1.4571 (X6CrNiMoTi17-12-2), AISI 316TiSimilar properties as 1.4404 but with guaranteed resistance to intergranular corrosion due to an increased titanium content.

RISER PIPES

HOse risersThe flexible hose riser is a product which has been devel-oped for special cases of application.

The hose is manufactured in the extrusion procedure as a highly wear-resistant flat hose. The inner and outer sheath consist of polyurethane (PU) and are provided with a round woven polyester insert. In order to simplify the mounting of cables and immersion electrodes, a polyurethane-reinforced belt has been vulcanized on the hose with loops.

Advantages little space requirement for storage and transport Quick assembly and disassembly, especially in the case

of temporarily limited use trinkwasserzulassung [German drinking water stand-

ards] according to KtW [plastics in contact with drink-ing water]

Areas of application: drainage mining and industry agricultural irrigation Water monitoring test well Waste disposal drainage

Optional accerssories: reel support clamps centring devices
