Production line and factory setup overview
A medium hygienic plastic-pipe line producing 20-63 mm single-layer PP-R hot- and cold-water pipe from certified virgin PP-R compound through sealed material handling, controlled colour dosing, single-screw extrusion, spiral-die forming, vacuum calibration, staged cooling, synchronized haul-off, permanent printing, dust-free length cutting and stacking, followed by dimensional, opacity, thermal-reversion and hydrostatic pressure testing.
Recommended lowest-entry line configuration Launch one single-layer 20-63 mm PP-R pipe family at 100-120 kg/h from certified hygienic virgin compound. Screen an SJ65/30 or 65/40-class extruder, colour-strip unit if specified, contracted dies and copper calibrators, dual-chamber vacuum/cooling tanks, two-belt haul-off, permanent printer, dust-free cutter and stacker. Fittings require a separate injection-moulding line. Do not market hot-water service until pipe-series, thermal-cycling and hydrostatic tests meet the named standard.
Production process and implementation sequence
- Hygienic compound certificate and lot release
- Sealed loading and controlled colour dosing
- Single-screw extrusion and die forming
- Vacuum calibration and staged cooling
- Synchronized haul-off and permanent printing
- Dust-free length cutting and stacking
- Dimension, opacity and heat-reversion inspection
- Hydrostatic and thermal service verification
Products, capacity and market fit
- Reliable hot/cold-water plumbing is needed in Afghan housing and institutions.
- Local pipe production reduces bulky imports and supports distributor stock.
- A 20-63 mm family addresses common internal plumbing diameters.
- Hygienic compound, socket-fusion compatibility and hot-water pressure life are essential.
- PP-R cold-water pipe - OD, pipe series/SDR, wall, material designation, opacity, marking and socket-fusion system - Buildings and institutional plumbing
- PP-R hot-water pipe - Named temperature/pressure class backed by hydrostatic and thermal-cycling qualification - Domestic hot-water systems after full validation
