Valves, fittings and pipe in PPH
PPH (polypropylene homopolymer) is a partially crystalline thermoplastic resin belonging to the polyolefin family.
PPh is the result of the polymerization of propylene (C3H6) with the help of catalysts.
The PPH line in latest generation Homopolymer Polypropylene consists of a complete range of pipes, fittings and valves to be used in the construction of process and service lines for conveying industrial fluids under pressure for maximum operating temperatures up to 100°C .
The entire line is made using Polypropylene Homopolymer resins MRS 100 (PP-H 100) according to classification DIN 8077-8078, DIN 16962 and approved by DIBt - Deutsches Institut für Bautechnik for use in industrial processes.
Features of the PPH
For use in piping systems, the latest generation Polypropylene Homopolymer, PPH, offers excellent performance up to high operating temperatures and high resistance to chemical attack thanks to the physical characteristics of the PPH material.
Among the main properties of the latest generation homopolymer resins we can mention:
High chemical resistance
The use of PPH (Polypropylene) resins, in addition to guaranteeing excellent chemical resistance, specifically against halogens and alkaline solutions, allows, thanks to the use of particular additives, the maintenance of high mechanical characteristics also in the transport of detergents and products similar chemists. The PPH material offers complete compatibility also in the transport of drinking water and water to be made potable, demineralised water and thermal waters for curative use as well as for physiotherapy.
Excellent thermal stability
Especially in the intermediate temperature range between 10°C and 80°C, typical of industrial applications, PPH guarantees performances of excellent mechanical and impact resistance with high safety factors.
Duration over time
The PPH material has a high circumferential breaking load value (Minimum Required Strength MRS≥ 10.0 MPa at 20°C) and made it possible to obtain extremely long life times of the installations, without any particular physical-mechanical decay.
PPH valves, PPH pipe and PPH fittings: a complete system
PPH is widely used in industrial applications due to its high resistance to chemical agents, the ability to operate in a wide range of temperatures and the joining system by means of polyfusion welding.
Our range in PPH (homopolymer polypropylene) is suitable for the assembly of process and service lines intended for the distribution of aggressive industrial fluids under pressure.
PPH systems lend themselves to a variety of applications, including mixing and dosing of chemicals and treatment of exhaust gases.
Our solutions have been selected by some of the major international metallurgical, iron and steel and mining companies, for extraction, surface treatment and acid regeneration processes.
