High-integrity clinical drainage stacks, laboratory chemical waste lines, and acoustic-dampened soil & waste piping engineered strictly to Saudi Building Code SBC 702 and Ministry of Health standards.
Direct pricing from the Jeddah plant, with technical submittal support.
Hospital sanitary stacks operate under intense chemical exposure from daily sanitizing washes, chlorine-based bio-decontamination fluids, and pharmaceutical lab discharges. ALFA's DIN 19531 uPVC drainage systems offer 100% non-metallic corrosion immunity and mirror-smooth interiors preventing pathogen colonization.
Engineered with deep-engagement rubber ring push-fit sockets that absorb axial thermal movement across vertical risers without stress buildup. Combined with heavy wall geometry to meet strict hospital acoustic noise attenuation requirements.
Hospital laboratories discharge aggressive bio-chemicals, formalin, sanitizing agents, and mild acids that rapidly corrode conventional cast iron or low-grade plastics.
DIN 19531 and BS EN 1329 govern inside-building soil and waste drainage pipes with high impact strength and rubber ring expansion joints.
uPVC exhibits universal resistance to chlorinated disinfectants, hypochlorite solutions, detergents, and quaternary ammonium compounds across temperatures up to 60°C.
Deep-seal traps (minimum 75mm water seal) and dedicated relief vent stacks engineered to Saudi Building Code SBC 702 prevent siphonage and vapor breakthrough.
Yes, ASTM D2564 heavy-bodied solvent cement is specified, creating homogeneous chemical weld joints with zero risk of joint separation inside shaft risers.
Acoustic insulation wraps or heavy-density uPVC drainage walls combined with elastomeric acoustic pipe clamps dampen water flow noise below 20 dB.
Yes, for continuous discharge temperatures exceeding 60°C up to 93°C, ASTM F441 CPVC Schedule 80 is recommended to prevent thermal pipe sagging.
Stacks undergo hydrostatic head water testing or air pressure testing (35 kPa for 15 minutes) with zero permissible pressure drop or joint sweating.
ALFA provides complete submittal dossiers including ISO 9001 certificates, chemical resistance tables, SASO compliance sheets, and third-party laboratory reports.
Push-fit rubber ring expansion sockets or engineered expansion loops are installed at every floor level (approx. 3.0 to 3.5m spacing) to absorb axial thermal movement.
Phased flatbed deliveries from our Jeddah factory reach Riyadh, Makkah, and Eastern Province healthcare projects within 24 to 48 hours of call-off.
