Patented glass-fibre reinforced multi-layer pipe, fusion-welded joint to joint. Made in Ahmedabad for 20,000+ installations across India.
Choose your duty
Patented multi-layer pneumatic pipe. A bigger bore at the same outside diameter and fused joints with nothing to leak, so the compressor works less for the same air at the tool.
Glass-fibre reinforced composite with a carbon UV shell. One material for the whole water block, a quarter of the thermal expansion of plain PP, and outdoor runs without cladding.
Polypropylene homopolymer as one homogeneous wall. No liner to lift and no bond line for an acid to find, with electrofusion on large bore.
Inside the wall · Patent No. 412111
Each line is engineered for one kind of service. If your plant has all three, we supply all three on one fusion system, with one fitter training and one site team.

View PPH"FR" in PPCH FR and PPRCT FR stands for fibre-glass reinforced. Suitability for any line depends on the fluid, its concentration, temperature and pressure together. Send us your service conditions and we confirm each line in writing.
Socket fusion fittings up to 160 mm (200 mm on PPH), electrofusion from 200 to 630 mm, flanges, branch adaptors and threaded transitions. All moulded to the same material as the pipe.
Large-diameter jointing
On a 300-metre run there are around fifty joints. Above 160 mm we join pipe by electrofusion, so no joint narrows the bore. Butt-fused systems leave a ring at every joint that the compressor or pump pays for continuously.
| Pipe size | Bore | Typical butt-fusion bead | Bore at joint | Flow area lost at each joint |
|---|---|---|---|---|
| 110 mm, PN 10 | 90 mm | 2 mm | 86 mm | 8.7% |
| 160 mm, PN 10 | 130 mm | 3 mm | 124 mm | 9.0% |
| 250 mm, PN 10 | 204 mm | 4 mm | 196 mm | 7.7% |
| 315 mm, PN 10 | 258 mm | 4 mm | 250 mm | 6.1% |
| Anjney electrofusion | Full bore | None | Full bore | 0% |
Bead heights are indicative for hot-plate butt fusion and vary with wall thickness, melt temperature and jointing pressure.
Why plants change
Lines like this are what our clients replace. Rust and scale narrow the bore, raise pressure drop and shed particles into air tools, valves and heat exchangers.
The same three lines serve very different plants. These are the services we supply most often, by industry.
Solar cell and module manufacturing
Module-line compressed air on PPCH; chiller, cooling tower, drain and utility water on PPRCT; and PPH ready for ETP and chemical lines. Every utility line from one supplier, on one fusion system. Plant-wise sizes and reference contacts are shared with project teams on request.

PPCH FR Pneumatic Pipe is Anjney's patented multi-layer, glass-fibre reinforced polypropylene pipe for compressed air, instrument air, nitrogen and vacuum. It is made to ISO 15874-2:2012 in 20 to 630 mm, protected by Indian Patent No. 412111, and PPCH is a registered trade mark. PPCH specifications.
PPRCT FR Composite Pipe carries cooling water, chilled water, cooling-tower, RO, DM, raw and hot water, and hot condensate. Its glass-fibre core cuts thermal expansion to 0.035 mm/m·K and its carbon UV layer allows outdoor runs without cladding. PPRCT specifications.
PPH is polypropylene homopolymer, the stiffest and most chemically resistant grade of polypropylene. Anjney PPH is a single homogeneous wall for acids, alkalis, chemical drains and ETP lines, made to EN ISO 15494 in 20 to 630 mm. PPH specifications.
FR stands for fibre-glass reinforced: a glass-fibre layer in the middle of the pipe wall. It does not mean flame retardant.
By socket fusion up to 160 mm (200 mm on PPH) and by electrofusion from 200 to 630 mm. We do not use butt fusion, because it leaves a bead inside the bore at every joint. See the fittings range.
