PPH (Polypropylene Homopolymer) vs. PPR vs. HDPE Pipes for Industrial Process Plants: Comparative Guide

Introduction: Thermoplastic Piping in Industrial Facilities

Selecting the right thermoplastic piping material is critical for conveying corrosive chemicals, compressed air, and hot process fluids. The three most common choices are PPH (Polypropylene Homopolymer), PPR (Polypropylene Random Copolymer), and HDPE (High-Density Polyethylene).

Comparative Material Properties

PropertyPPH (Homopolymer)PPR (Random Copolymer)HDPE (PE100)
Continuous TemperatureUp to 95°CUp to 70°C – 90°C (hot water)Up to 60°C
Chemical ResistanceHighest resistance to industrial acids & alkalisModerate chemical resistanceExcellent for acids & underground runs
Flexibility & DuctilityRigid, high modulusDuctile, good impact absorptionHighly flexible, resists ground shifting
Primary ApplicationChemical processing, pickling, acid pipingCompressed air, hot water plumbingETP drainage, buried pipelines, effluent
