PE Pressure & Water Supply Pipes — Outside diameter 200 mm

Pipes in this category are manufactured to ISO 4427 and EN 12201-2 for potable drinking water, pressurized agricultural irrigation, and industrial fluid transmission. The published product range comprises PE100 Water Pressure Pipe (P001) and PE80 Water Pressure Pipe (P002).

The fundamental mechanical distinction is the design stress: 8.0 MPa for PE100 versus 6.3 MPa for PE80. The nominal pressure rating follows the standard relation PN = 20 × design stress ÷ (SDR - 1). Consequently, to achieve a 16 bar rating (PN16), a PE100 pipe requires SDR 11, whereas a PE80 pipe requires SDR 9, which necessitates a substantially thicker wall.

The catalog dimensional envelope covers outside diameters from OD 16 mm up to 630 mm. Pressure classes range from PN4 to PN25, corresponding to standard series SDR 41, SDR 33, SDR 26, SDR 21, SDR 17, SDR 13.6, SDR 11, SDR 9, and SDR 7.4.

Supply packaging depends strictly on outside diameter: diameters up to 110 mm are produced in continuous coils of 100 m and 200 m to eliminate intermediate joints in distribution networks, while sizes from 63 mm upwards are delivered as straight 6 m and 12 m bars.

Pressure pipe jointing is accomplished through three engineering methods: butt fusion for straight bars and large-diameter mains, electrofusion fittings containing embedded heating coils for critical junctions, and mechanical compression fittings for coiled pipes up to 110 mm.

Pipes must rest on a prepared bed of uniform sand or screened soil free of sharp stones, with a minimum thickness of 10 to 15 cm. Sidefill compaction in staged lifts is essential to restrain lateral deflection. Prior to backfilling and commissioning, hydrostatic field pressure testing must be executed in accordance with the project specifications.
