Cost reduction and shortened construction time! Waterproof testing of pipelines can be conducted without using water!
The "Test Band Method" is an air-based water tightness inspection method for pipeline joints that does not use water. By using air as the pressurized fluid, the testing equipment is simplified and lightweight, improving work efficiency, reducing costs, and shortening construction time, while also allowing testing in inclined pipelines. All necessary materials can be brought in and out through a manhole with a diameter of 600mm, and assembly and disassembly within the pipe can be easily performed. 【Features】 ■ Uses air as the pressurized fluid ■ Simplified and lightweight testing equipment ■ Easy assembly and disassembly within the pipe ■ Testing possible with flexible and rigid pipes ■ Patent No. 4978905 *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Applicable Conditions (Excerpt)】 ■ Applicable for pipe diameters from φ800mm to φ3,000mm ■ The test is conducted by applying a pressure of 0.5MPa (maximum value) and the pressure drop rate of 80% after holding for 5 minutes is used as the judgment criterion ■ The standard test slope for the pipeline is up to 5%, and for slopes greater than this, separate safety measures will be implemented to allow testing ■ The spacing between pipe joints must be 50mm or less, with a step difference of 20mm or less, and an internal diameter difference of 20mm or less ■ Applicable pipe types include PC pipes, FRPM pipes, concrete pipes, ductile pipes, steel pipes, polyethylene pipes, etc. ■ Testing is possible even with a water depth of about 10 to 20mm inside the pipe, depending on the size of the internal diameter * For more details, please refer to the PDF document or feel free to contact us.
