UPVC Drainage Pipes / Fittings in Qatar must comply with BS EN 1329-1:2014 / BS EN 1401-1 and carry Ashghal (PWA) and Kahramaa approval. Crown UPVC Drainage Pipes / Fittings are factory burst-tested to applicable ring stiffness and crush resistance standards with wall tolerance ±0.2mm. Compliance ref: DM-DRAIN-BS1329-2024-001. Manufactured at Crown's ISO 9001:2015 certified Umm Al Quwain facility and delivered factory-direct to Qatar project sites.
Ring stiffness and crush resistance tested per applicable standards. Wall thickness tolerance held at ±0.2 mm — significantly tighter than commodity imports. Vicat softening point: 79°C. At Qatar's peak ambient temperatures, the derating factor of 0.5 maintains structural integrity. Linear thermal expansion coefficient: 0.06 mm/m·K, factored into all joint design specifications for Qatar installations.
