Flexible earthquake-resistant cast iron pipeIt has special transportation requirements: pressure transportation of oil, water, gas and related liquids and gases, so it is flexible and resistant.The air tightness requirements of cast iron pipes are very high.The air tightness test must be strictly carried out on the flexible anti-seismic cast iron pipe production line.It also testedAir tightness inspection equipmentapplicability.

Most of the traditional leak detection methods use bubble method and smear method.The bubble method is to immerse the workpiece in water, fill it with compressed air, and thenThe flexible anti-seismic cast iron pipe collects the bubbles leaking out of it within a certain period of time to measure the leakage amount.The smearing method is flexible anti-seismic cast ironApply a bubble-prone liquid such as soapy water to the surface of the workpiece that is filled with a certain air pressure inside the pipe. Observe the bubbles produced in the ductile iron pipe.situation to detect leaks Quantity size.Obviously, neither of these two methods can meet the high-precision and high-efficiency production requirements, affecting the measurementaccuracy requirements.Therefore, more sophisticated automated testing equipment must be used to improve detection efficiency and accuracy.
