Plastic pipes & systems
Pressure pipe systems made of PE, PP, PVDF and PVC – corrosion-free, lightweight, chemically resistant and fusion-welded. For water, gas, wastewater, chemicals and ultra-pure media, including fittings, valves and connection technology.
The right plastic system for every medium
From drinking-water and gas lines to highly aggressive chemicals – we supply the matching plastic pipe system including fittings, valves and welding technology.
PE 100 / PE-RC
Polyethylene for pressure pipes – tough, durable, ideal for buried and trenchless installation.
- Drinking water (EN 12201)
- Gas (EN 1555)
- Wastewater & industry
- PE 100-RC for no-dig
PP (PP-H / PP-R)
Polypropylene for industry, chemicals and building services – broad chemical resistance.
- Chemical & process lines
- Heating & cooling (PP-R)
- Ventilation & wastewater
- up to approx. 80–95 °C
PVDF
Fluoropolymer for the highest demands – ultra-pure media, aggressive chemicals, high temperatures.
- Ultra-pure water & semiconductors
- Aggressive acids/alkalis
- High temperature up to ~140 °C
- Pharma & chemicals
PVC-U / PVC-C
Rigid PVC and chlorinated PVC – proven for water and chemicals, economical and robust.
- Water & irrigation
- Acids & alkalis
- PVC-C for hot water
- Solvent-cement & flange connection
Materials at a glance
Reference values for orientation – we agree the exact design (pressure rating/SDR, temperature, medium) with you.
| Material | max. continuous temperature | Typical application | Special feature |
|---|---|---|---|
| PE 100 (PE-HD) | ~ 40 °C (short-term 60 °C) | Drinking water, gas, wastewater | tough, impact-resistant, no-dig (RC) |
| PP (PP-H/PP-R) | ~ 80–95 °C | Chemicals, industry, heating | broad chemical resistance |
| PVDF | ~ 140 °C | Ultra-pure media, chemicals, semiconductors | highest purity & resistance |
| PVC-U | ~ 60 °C | Water, chemicals, irrigation | robust, economical |
| PVC-C | ~ 90 °C | Hot water, chemicals | higher temperature than PVC-U |
| ECTFE | ~ 150 °C | highly aggressive media | for extreme conditions |
Fusion-joined – tight and durable
Plastic pipes are fusion-welded and thus permanently tight – without corrosion, without gasket wear. Depending on the system we supply the matching technique:
- Heated-tool butt welding (PE, PP, PVDF)
- Electrofusion couplers (PE)
- Socket / IR welding
- Flange connections with stub end & backing flange
- Solvent-cement joint (PVC-U/-C)
Advantages over metal: corrosion-free, lightweight, smooth inner wall (low deposits & pressure losses), chemically resistant and low-maintenance.
Frequently asked questions about plastic pipes
Which plastic pipe for drinking water?
Usually PE 100 (EN 12201) for buried lines; for building installation, PP-R or PVC-C depending on requirements.
Which material for aggressive chemicals?
PVDF or ECTFE offer the highest chemical and temperature resistance; PP is the economical solution for many media.
Up to what temperature can plastic pipes be used?
Depending on the material: PE ~40 °C, PVC-U ~60 °C, PP ~80–95 °C, PVC-C ~90 °C, PVDF ~140 °C, ECTFE ~150 °C.
How are plastic pipes joined?
Fusion-welded (butt, electrofusion coupler, IR) or via flanges; PVC also solvent-cemented.
Enquire about a plastic pipe system?
Medium, pressure, temperature, nominal size and quantity are enough – we recommend the material and supply the complete system including fittings and welding technology.
