Sewer Robotics Concrete sample test with WJ200 at 1500bar

When concrete is found inside pipelines, it's not always clear who left it there or what type of concrete was used. To determine who should pay for cleaning and what water pressure is required for removal, testing is essential. Although concrete may appear similar and even share the same name (e.g., concrete, calcium), the pressure needed to effectively remove such deposits can vary from 500 bar (7,250 psi) to 2,800 bar (40,000 psi).
The best way to find the minimum required pressure for deposit removal is through testing. At Sewer Robotics, we gladly accept samples for a free-of-charge sample test to answer the question: "What pressure does it take to remove this material?" We strive to duplicate test conditions by placing samples inside a pipe and testing with a water jet cutting robot.
Are you also dealing with solid obstructions? If you'd like to know the pressure required for Sewer Robotics' water jet to remove the deposit, please contact [e-mail] to coordinate shipping your sample to our test facility.
*Previous Pressure Tests:*
These concrete samples were initially tested at 500 bar (7,250 psi) without results. At 1,000 bar (14,500 psi), the water blast slowly cuts into the concrete. At 1,500 bar (22,000 psi), the material is cut into smaller pieces for efficient removal.
