ARMORED POLYETHYLENE PIPES AND FITTINGS

CONSTRUCTION

The PE-NP-AS polyethylene armored pipe consists of:

• internal, line pipe (pressure), with an antistatic layer
• an outer pipe (“protective armor”) made of flame-retardant and antistatic polyethylene, tightly fitted over the service pipe.

TECHNICAL PARAMETERS

• standard range of line pipe diameters from DN32 to DN400 mm,
• standard nominal pressure PN 6 – PN 25
• standard length L = 6m

At the customer’s individual request, it is possible to make sections of different lengths, dimensions, and pressure, as well as segment fittings, e.g. elbows, tees as a supplement to the entire installation.

THE LISTED MEDIUM CAN BE TRANSPORTED:

• water
• water with a suspension of solids and mineral compounds present in mine waters
• brine
• non-flammable liquids
• aggressive liquids
• chemically compressed air in shafts and underground workings of mines
• extracting non-flammable minerals (e.g. copper, salt, sand)

PIPE JOINING METHODS

• Victaulic System couplings
• flange connections
• butt welding of the fitting
• screw clamps
• PE / steel transitions
• flange connector

ADVANTAGES OF PE-NP-AS PIPES

• high resistance to crack propagation as a result of external damage,
• higher impact resistance compared to GRP, PVC, PP
• high durability of the pipeline (several times higher than that of steel pipes) – especially visible in workings with unfavorable microclimate,
• possibility of cutting to the desired length at the place of installation,
• the possibility of building a hydrant anywhere,
• possibility of immediate clamping of pipes with a screw clamp,
• simple installation and servicing of the pipeline (4 or 2 bolts) using Victaulic 995 or 905 couplings,
• high flexibility, the possibility of pipeline correction without the need to use elbows or wedges while maintaining specific bending radii,
• approx. 50% increase in work efficiency in assembly and disassembly compared to flanged pipes,
• lighter than steel pipelines, easier transport,
• high abrasion resistance,
• low coefficient of absolute internal roughness – 20% reduction in flow losses,
• complete absence of corrosion of polyethylene pipes,
• significantly reducing the phenomenon of internal fouling, resistance to impact and brittle cracks, odorless – odorless (they do not emit odors like e.g. resins)
• possibility of multiple use of all elements,
• Can be connected to other installed pipelines with Victaulic flange or groove belts.
