PPH Piping System

Overview

Polypropylene homopolymer (PP-H) piping system is a polyolefin and semi-crystalline thermoplastic system made from the polymerization of only propylene. PPH pipe has high tensile strength, which makes it suitable for use in aggressive and abrasive applications where other piping materials would be damaged. Sangir’s engineered PPH piping system is manufactured in accordance with DIN 8077 for hydrostatic design basis and follows SDR (Standard dimensional ratio) and PN (Nominal pressure in bar) pressure rating, which is the same in all diameters. SDR 11 = 150 PSI = PN 10 bar. PP-H piping is highly resistant to chemicals, acids, and alkalis, that are found in various industrial applications. PPH pipe fittings’ unique combination of properties, makes it an ideal choice for use in pickling plants chemical processing industry, pulp & paper, nuclear power, non-ferrous extraction, pharmaceutical, WTP & WWTP, and Food & beverage industries, where harsh chemicals and high temperatures prevail.
