3 Things You Need to Know about Nu Drain CIPP Epoxy

3 Things You Need to Know about Nu Drain CIPP Epoxy Cured in place pipe (CIPP) is one of the most common products used in the pipe rehabilitation industry today. From repairing corrosion, erosion and general degradation of a pipeline, CIPP is a trenchless technology product that can solve many common problems associated with aging pipelines.

This product can be used on many types of pipelines including sewer mainlines and laterals, industrial and waste pipelines. The American Society of Testing Materials (ASTM) tests cured in place thermosetting pipes to make sure they are able to withstand certain conditions and comply with NSF standards. It’s these tests and certifications that allow for safe products to be serviced to our communities and in addition, help potential installers understand the unique capabilities of their products. Nu Flow Technologies’ products have an excellent track record of meeting and exceeding ASTM standards. Here are three certifications you may have not known about Nu Flow Technologies’ CIPP epoxy.

1) ASTM D790 Flexural Properties Certified

Flexure tests determine the strength of the material and a CIPP sample test is performed after the installation process or curing process. The most common materials that are tested for flexural are plastic materials, composites, concrete, and ceramics. Epoxy is a type of extremely hard plastic that is used in Nu Drain’s pipelining. A bar of the CIPP material is place across a span, the length is typically 16 times the thickness of the sample and then it is loaded at a constant rate at its midpoint. In order for the CIPP sample to pass the ASTM D790 standard, a minimum axial sample length of 20 times this thickness is required.

2. ASTM D638 Tensile Properties Certification In this particular test the sample is cut into a “dog bone” shape with two wide ends at each side with a smaller thickness in-between. The reason why the middle section is reduced is because it concentrates the stress point in a controlled area. The sample is then pulled into tension – while this takes place measurements are taken. The change in sample length and tension weight are recorded until the sample begins to stretch and break. Tensile tests are another way to measure the structural strength of the CIPP epoxy while also measuring what kind of force the material can withstand.

3. ASTM D543 Chemical Resistance Chemical resistance tests are needed to prove the long-term strength and quality of the CIPP epoxy.

Two versions of the CIPP epoxy are tested: one was exposed to a given chemical and the other was not. Typically, they compare the two different samples on the overall physical properties such as flexural and tensile properties, weight and hardness changes.

Nu Drain by Nu Flow Technologies meets and exceeds all three of these ASTM requirements and has a life expectancy of over 50 years. There a many other certifications Nu Flow Technologies’ products qualify for including NSF/ANSI 14 and NSF SE 13004 standards. Understanding the testing process and requirements gives us a better understanding of the strength of technology behind CIPP epoxy lining and what it can offer to the world’s deteriorating pipeline systems.
