Definition - What does Chemical Resistance mean?
Chemical resistance is the capacity of a material or product to withstand exposure to chemicals in a particular environment. Through exhaustive testing, researchers develop chemical resistance charts to document their findings.
Chemical resistance is a significant concern in the selection of pipes and other products used in the trenchless construction industry.
Trenchlesspedia explains Chemical Resistance
It is well known that chemicals can be harmful to pipes. The damage may take place over a long period before it is discovered during inspection. Trenchless rehabilitation techniques can be used to repair or line pipes suffering from chemical corrosion rather than replacing them.
Newer piping materials, such as thermoplastics, are created with chemical resistance in mind. Temperature, chemical concentration, and length of exposure are some of the factors used in determining the chemical resistance capabilities of a material. Chemical resistance charts provide the results of laboratory testing and should be considered when procuring pipes for use in an environment where chemical exposure is likely.
