Did corrosion start in your drinking water line after 3 years? Are you experiencing leakage problems in your plumbing pipe? Pressure losses in your agricultural irrigation system? Common cause of these problems: wrong potable water pipe selection. Industrial PVC pipe technology offers permanent solutions to chronic problems created by metal alternatives. However, mistakes in metric PVC pipe dimensions, connection types, and pressure classes jeopardize entire system performance. Düzgünler Plastik produces uPVC pressure pipe with proven service life exceeding 50 years in 40 countries since 1975.
Konya Karatay Municipality will lay 5 km drinking water line. Jointed socket pipes are ideal choice here. Why? Rubber gasket system tolerates ground movements. Provides flexibility in earthquake-risk zones. Installation speed 40% higher than solvent weld systems. In large projects, time = cost. At 200-400 mm diameters, jointed socket is both economical and practical. In Düzgünler Plastik jointed socket pipes, special square-section gasket groove guarantees leak-proofing.
EPDM rubber gasket maintains elasticity between -40°C and +80°C. Chlorine and ozone resistance works 50 years without degradation in drinking water. Pre-stress design compensates pipe tolerances. Our test results: zero leakage at 16 Atm pressure.
Hospital PVC-U pipe selection requires hygiene criteria. Solvent weld PVC pipe systems are standard here. Connections joining at molecular level don't provide ground for bacterial growth. Smooth inner socket surface prevents biofilm formation. At 20-110 mm diameters, solvent weld fits narrow spaces in plumbing rooms. PVC water main pipe doesn't release metal ions - critical for laboratory analyses.
Field Experience:
Izmir Plumbing Forum - Master Mehmet (18 years experience): "I use only solvent weld in hospital projects. Lines I laid in 2015 still zero failure. Pipe interior smooth despite high chlorine level. Jointed socket doesn't guarantee such cleanliness. Solvent weld mandatory in hygiene-requiring places."
Multi-story building example: 15-floor apartment, ground elevation +100m, tank +150m. Static pressure = 5 Atm. Pump pressure = 4 Atm. Total = 9 Atm. 10 Atm pipe selected - sufficient on paper. In reality? Water hammer added instant +3 Atm. System exposed to 12 Atm. Result: pipe burst in 18 months. Correct selection: 16 Atm pressure clean water pipes. Safety factor should be 30%. Düzgünler Plastik engineers offer pre-project pressure analysis.
• 4 Atm: 1-3 story buildings, low-pressure irrigation
• 6 Atm: 4-8 story buildings, garden irrigation systems
• 10 Atm: 9-15 story buildings, medium-pressure industrial
• 16 Atm: High-rise buildings, pump stations, long-distance transmission
Gooseneck pipes prevent turbulence created by 90° elbows. Standard elbow: 15% pressure loss. Gooseneck: 3% pressure loss. In 1 km line, difference = 2 meter water column. Energy cost drops 12% annually. In agricultural irrigation, pump electricity bill reduces 500 TL monthly. PVC water main pipe geometry optimizes flow physics. Düzgünler Plastik R&D minimized flow resistance by fixing gooseneck angle at 22.5°.
Production Ekrem Düzgün started in 100 m² workshop in 1975 reached 30,000 m² facility under Ziya Düzgün and Kemal Düzgün management. Engineering knowledge gained as Turkiye's first submersible pump column pipe manufacturer transferred to potable water pipe technology. We design our own extrusion machines - not dependent on imports. Export to 40 countries is global approval of our quality. ISO 9001:2015 and TS EN 1452 certificates tested in every batch. In our industrial PVC pipe production, we use no material except virgin PVC - 100% pure raw material guarantee.
Half-century field data shaped our formulation. UV degradation problems in 1980s are solved today. In chlorine resistance tests, we pass 10-year accelerated aging simulations. Metric PVC pipe dimensions optimized with feedback from thousands of projects.

Answer: We recommend solvent weld pressure clean water pipes in apartment internal plumbing. Easy installation in narrow plumbing rooms, permanent leak-proofing, hygiene advantage against bacterial growth. At 20-63 mm diameters, solvent weld is standard for uPVC pressure pipe. Jointed socket preferred in outdoor line applications like garden irrigation. Düzgünler Plastik offers TS EN 1452 compliant product range for both systems.
Answer: 110 mm diameter sufficient for 6-8 unit apartments. 125 mm used in 12+ units or commercial buildings. Flow difference 28% - seems small but critical. Wrong selection causes pressure drop in upper floors. Hydraulic calculation required: simultaneous use coefficient, line length, elevation difference. PVC-U pipe dimensions should be determined project-specific. Düzgünler Plastik technical team provides free sizing support.
Answer: Yes, lasts 50 years with UV-stabilized formulation. However, condition: direct sunlight + above-ground installation = painted insulation required on pipe. In above-ground temporary lines, aluminum foil wrap recommended. Düzgünler Plastik uPVC pressure pipe shows strength loss below 5% after 5000-hour UV test. For permanent outdoor line, underground laying healthiest. Jointed socket pipes more tolerant to ground movements.
