Why Municipality Approval Matters
Dubai Municipality and Sharjah Municipality require all plumbing materials used in new builds and renovations to be approved and specification-compliant. Using non-approved Pipes / Fittings exposes the contractor to inspection rejection, project delays, and financial penalties. Furthermore, the completion certificate is only issued after confirming compliance of all materials used.
Crown Plastic PPR Pipes / Fittings are approved for UAE construction projects and manufactured to German DIN 8077/8078 standards — the global reference for Polypropylene Random Copolymer (PP-R) pipes. We provide all required approval certificates and technical submittals for consultant and owner material submissions.
Heat Fusion Welding Advantages
The PPR piping system features heat fusion welding technology that creates a chemically homogeneous joint between pipe and fitting. Unlike mechanical connections or solvent welding, heat fusion produces a connection point stronger than the pipe itself, completely eliminating leak risks.
Heat Fusion Specifications:
- • Welding temperature: 260°C ± 10°C
- • Heating time: depends on pipe diameter (7-24 seconds)
- • Joint strength exceeds pipe strength by 15-20%
- • No additional materials needed (solder, solvents, sealants)
- • Clean process suitable for potable water systems
Durability in UAE Climate
Plumbing systems in the UAE face unique challenges: elevated summer water temperatures exceeding 45°C even in cold water lines, high-salinity water, and daily thermal cycles. Crown Plastic PPR Pipes / Fittings are engineered to handle these conditions:
- Continuous operation at 70°C for 50+ years (DIN 8077/8078)
- Short-term peak resistance up to 95°C
- Complete resistance to scale build-up and internal calcification
- Available in PN10 (SDR11), PN20 (SDR6), and PN25 (SDR5) ratings
- Inherent thermal insulation reduces heat loss in hot water lines
Crown Plastic PPR Range
Crown Plastic provides a comprehensive PPR Pipes / Fittings range from 20 mm to 160 mm diameters, including straight pipes, elbows, tees, reducers, valves, and transition fittings to metallic systems. All products are stocked with 24-48 hour delivery in Dubai and Sharjah.
