HIGH DENSITY POLYETHYLENE & POLYPROPYLENE PIPING SYSTEMS

POLYPROPYLENE PIPING

 D-U-N-S ® 91-811-2264

Physical Properties

The physical properties of polypropylene combine strength, low weight, abrasion resistance, impact strength and a wide operating temperature range, making it a very suitable material for use in load bearing products. Combined with excellent all round chemical resistance and low water absorption, these properties combine to provide a material that meets all of the requirements for use in a piping system.

 

 

Purity

PPH complies with guidelines listed in the Federal Register, CFR Title 21, chapter 1, § 177.1520 a (1) for polypropylene and c (1.1) for compounds. Polypropylene is suitable for transport of potable water, foodstuffs, and high purity deionized water.

 

Good Temperature Resistance

The polypropylene piping system is pressure rated to 150 psi (10 bar) at 70°F (21°C) with a long term safety factor of 2.1. The upper long term temperature limit for polypropylene is 176°F (80°C) and the temperature limit for short term use is 212°F (100°C). However, as with all thermoplastic piping systems, an increase in temperature is combined with a decrease in operating pressure.

Chemical Resistance

The chemical resistance properties of polypropylene are excellent. It is resistant to aqueous solutions of acids, alkalis and salts and to a large number of organic solvents. This wide range of chemical resistance allows this material to be used for many piping systems that handle different chemicals including caustics, acids and solvents. Polypropylene is not suitable for handling concentrated oxidizing acids and halogens.

 

Beta (β) PP-H Material

The material used in this system is an US FDA approved pigmented Group 1, Class 2 Beta neucleated homopolymer polypropylene. The addition of a pigment improves the resistance to degradation by ultraviolet light and weathering, prevents light transmission

into the wall of the pipe, and limits any embrittlement to the outside of the pipe wall. This material is especially compounded to have improved mechanical strength, safety factors, and low temperature impact resistance.

This material meets the requirements of ASTM D4101.
