Benefit of Material to Systems Application
Polypropylene pipe offers high strength, very good chemical resistance, non-toxicity and ultra-clean pipe walls for high purity water applications such as DI (deionized) water, R/O (reverse osmosis) water, and UPW (ultrapure water). Other industries require the high purity available with PP, such as chemical, semi conductor, biotechnology, healthcare, and universities.
Types of PP offer high internal pressure resistance, long lifetime at elevated temperatures (up to 195°F), high stiffness and high impact strength (especially at temperatures below freezing). Other advantages include low pipe weight, easy and safe handling/installation, noise dampening, and excellent corrosion, abrasion, stress crack, and chemical resistance. Finally, special manufacturing processes clean and package the pipe in clean rooms to ensure purity.
System Application and Material Usage
PP systems can be joined with either fusion joints or mechanical joints, depending on size, system requirement, and application. When permanently bonded systems are not an option, several different kinds of 'mechanical joint' systems are available. Threads and flanges are the most common types of mechanical joints, though several PP systems feature a different kind of connection which is much quicker and less cumbersome than flanging. Threads are used mainly in conjunction with 'true-union' type fittings, allowing components or sections of the system to be quickly and efficiently assembled and disassembled repeatedly with no loss of system integrity. The same pipe is used for both fusion and mechanical joining methods.
Polypropylene high chemical resistance makes it inert to most solvents, so permanent bonding cannot be achieved through a solvent cement process.
Butt fusion, socket fusion and IR non-contact butt welding are welding processes used with PP.
