PPH

PPH valves and piping are the cost-effective answer to hot caustic and alkaline service. PPH (polypropylene homopolymer) stays stable up to 85°C where sodium hydroxide, potassium hydroxide and similar media attack lesser plastics — which is why chlor-alkali plants and caustic-dosing systems rely on it. Huiya supplies a complete PPH range — pipe, fittings and pneumatic ball valves — in both DIN metric and ANSI/ASTM dimensions to suit project specifications worldwide, for chlor-alkali, chemical processing and wastewater applications. Every product is backed by a 12-month quality warranty. For hot alkaline duty, PPH is usually the most economical material that survives the job, keeping PVDF in reserve for concentrated acids.
