Weight	✅ Lightweight (~1/5 of DI)	✅ Comparable
Design Life	50+ years	50+ years
Hydraulic Smoothness	C=150 (Hazen-Williams)	C=150
Saudi Aramco Approved	✅ #10116102	Varies

In Saudi Arabian infrastructure applications, Sch 40 piping from ALFA AL-ARABIA offers significant advantages in corrosion resistance, installation efficiency, and total lifecycle cost compared to Sch 80 alternatives. The complete immunity of thermoplastic pipes to sabkha soil corrosion and chloride attack is particularly valuable in coastal regions (Jeddah, Dammam, Jubail, Yanbu).
