HJplastics manufactures high-performance PVC pipes that combine exceptional strength with outstanding flow characteristics. Our Class 200-315 pipes exceed ISO 4422 standards, featuring 25% higher hydrostatic design basis (HDB) than conventional PVC. The bi-axially oriented molecular structure provides 40% greater impact resistance (ASTM D2444) while maintaining dimensional stability across -5°C to 60°C temperature ranges. Available in 4m-6m lengths from 1/2" to 24" diameters, our pipes feature distinctive blue stripe marking for easy pressure class identification. The ultra-smooth interior (Ra 0.08μm) maintains Hazen-Williams C-factor of 150+ after decades of service, reducing pumping costs by up to 18%. We utilize lead-free stabilizers and food-grade compounds that meet the strictest international drinking water standards including WRAS and ACS.
