Tightness Testing<\/h2>\n\n\n\n

However, our rehabilitation vehicles are not exclusively used for rehabilitation; we also perform tightness tests on newly installed or rehabilitated drainage systems. This is generally done in accordance with DIN EN 1610. <\/p>\n\n\n\n

Tightness tests can be performed with air as a pressure or vacuum test, as well as with water.<\/p>\n\n\n\n

Sewer sections are sealed airtight at the end and at the connection lines with inflatable stoppers. Overpressure or underpressure is applied to the section via a test element. Depending on the material, nominal diameter, and length of the section, this pressure must be maintained for a specified time to classify the line as tight. All measurement and control processes are fully automated by the system. <\/p>\n\n\n\n

The program generates a measurement report as proof for the client. All probes and measuring instruments undergo annual calibration to continuously ensure accurate results and, consequently, impeccable quality. <\/p>\n\n\n\n

Tightness Testing After CIPP Rehabilitation<\/h3>\n\n\n
\n\n

Performing tightness tests after rehabilitation with a CIPP liner<\/strong><\/p>\n\n\n\n

After the liner rehabilitation is complete, a tightness test with air<\/strong> is performed.<\/p>\n\n\n\n

Before the tightness test<\/strong> can be carried out in the sewer after rehabilitation, the sewer must be thoroughly cleaned using a flushing nozzle.<\/p>\n\n\n\n

To test the tightness of a rehabilitated sewer, extensive special equipment<\/strong> is required.<\/p>\n\n\n\n

The sewer section to be tested is first sealed off using test stoppers. Pressure hoses are connected to the stopper and the test unit. The pressure test unit contains a computer with special software storing all DIN standards for pressure tests. After selecting the standard, the test program begins computer-controlled. This prevents procedural errors by the test operator. Sensors in the test unit then determine whether the pipeline meets the test criteria according to DIN. <\/p>\n\n\n\n

After the test is completed, the test result<\/strong> can be immediately printed as a graphical representation in the pressure measurement diagram, allowing for on-site determination of whether tightness was confirmed for the section being tested.<\/p>\n\n\n\n

Wastewater sewers must be tight. Leaky wastewater sewers pollute groundwater and soil. The water tightness<\/strong> of wastewater sewers and pipes must be ensured according to the test requirements of DIN EN 752-2. <\/p>\n\n\n\n

The standard procedure is tightness testing in pipes and manholes with air. Optionally, tightness testing can also be performed with water. <\/p>\n\n\n\n

All essential test standards for the testing application are stored in the test unit’s computer, thereby simplifying the preparation and execution of the pressure test.<\/p>\n\n<\/div><\/div><\/div>\n","protected":false},"excerpt":{"rendered":"
