As with all piping systems, proper selection and design is necessary to ensure that a successful installation can be made. Before using this polypropylene piping system, the user should ensure that the polypropylene is suitable for contact with the liquids to be handled. This information may be readily found in a chemical resistance chart. If polypropylene is chemically compatible and the operating temperature and pressure are within the previously discussed limits, then the system may be used. However it should be designed to include allowances for expansion and contraction, pressure drops and proper pipe support.


Polypropylene Pipes are available as per DIN 8077 standards in RAL7032 color. They are widely used in industrial processing. They are light weight, highly corrosion resistant and have high abrasion resistance. They can be operated at a wide range of temperatures upto 110°C. PPH also offers excellent chemical resistance to many aqueous solutions of acids, alkalis and salts, and to a large number of organic solvents.


Waste – Over a period of many years, polypropylene has become a preferred material for handling many different types of liquid waste. This material’s wide range of chemical

resistance makes it very suitable for handling the wide range of different chemicals and mixtures that are found in different waste streams. The unsuitability of polypropylene for use with concentrated oxidizing acids is generally not a problem because these acids will usually be diluted before they are disposed of. The high resistance of polypropylene to solvents is particularly important, because many solvents do not mix in water and often end up floating in a concentrated form near the top of the pipe. Thus, even though a waste stream may contain only 1% of a solvent, it is often not possible to regard this dilution because most of the solvent will often float to the top of the pipe. The material’s high temperature capabilities are also important in enabling it to handle any exothermic reactions that may occur when different chemicals mix.


Deionized Water – Large volumes of distilled or deionized water are used by a wide range of different industries. This water is often used for diluting chemicals, washing and

rinsing. Polypropylene is commonly used as a piping material for conveying this water. Although it does not have the ultra-purity of PVDF, polypropylene piping systems are able to maintain the purity required in all but the most demanding installations. Fusion joining gives fast reliable joining without the use of hazardous and noxious solvents that may contaminate the water. The total quantity of added lubricants and organic materials in polypropylene is far less than found in many other plastic piping materials. The use of a pigmented material is recommended to reduce degradation of the pipe material from ultraviolet light. The pigmented pipe wall will prevent the transmission of ambient light into the pipe material. This prevents possible degradation of the pipe wall and corresponding particulation of plastic into the water stream.


Caustic Solutions

The chemical resistance of polypropylene to caustic solutions such as potassium hydroxide and sodium hydroxide is very good. The fusion joining method gives strong   joints that are resistant to attack by these strongly caustic solutions. This contrasts to solvent cemented joints which may be attacked by some caustic solutions. For these reasons polypropylene is often used to transport caustic soda used for neutralizing acidic waste streams.


General Chemical Handling

The wide range of chemical resistance of polypropylene makes it suitable for use in applications where a piping system may be required to carry different chemicals or mixtures of chemicals. In this case polypropylene is often found to be one of the most suitable materials for handling combinations of many chemicals
