Mining & Tunneling

Alvenius has been an important supplier of corrosion protected steel pipe systems to mining and tunneling projects all over the world for more than 50 years. Today Alvenius is a world-wide concept used as a term for quick connected pipe systems, but the original Alvenius quality stands for itself.

Hot dip galvanized pipe systems

Hot dip galvanized pipe systems are used for underground applications such as transport of water, compressed air, dewatering, slurry and back filling. Alvenius offers two complete pipe systems, K10 or type Victaulic. K10 is a shouldered system based on metric standard for pressures up to 25 bar (360 psi) and Victaulic a grooved system based on ISO standard for pressures up to 80 bar (1160 psi). Diameter range 48 mm – 508 mm (2" – 20"). High quality, low weight combined with the quick coupling system result in low cost for installation, long durability and a minimum need of maintenance.

Thermoplastic coated steel pipe system (TP pipes)

The Alvenius steel pipe system, inside and outside coated with thermoplastic, combines the strength of steel and resistance of thermoplastic to cope with a wide variety of corrosive media. The pipes and fittings are joined using Alvenius quick couplings or flanges to eliminate expensive and time consuming welding. Pressures up to 70 bar (1000 psi). Diameter range 89 mm – 508 mm (3"-20") The products have an extremely good adhesion so there is no risk of scaling or cracking. Elongation at break is 800 %. Working temperature continuous in air + 65 deg. C /150 deg. F.

The TP pipes are used in applications such as heap leaching for copper, gold and zink, dewatering, process water, fire fighting and for media with acid water, high content of chloride or salt.

The TP pipes have superior resistance to pitting corrosion and have a significantly longer service life than for example stainless steel 316L.
