Device and method for testing pipeline fire resistance

Abstract

The invention provides a pipeline fire protection ability testing device, comprising: a burner, used to burn the pipeline, and the flame range of the burner forms a fire area; a sensor, used to sense the fire area and / or At least one physical parameter of the pipeline and / or non-pipeline outside the fire area, and output the sensing result; the data acquisition system stores the data determined by the relationship between the material performance reserve coefficient of the pipeline and the physical parameter the warning value, calculate the physical parameter of the pipeline according to the sensing result of the sensor, and compare the physical parameter of the pipeline with the warning value, if the physical parameter of the pipeline reaches or exceeds the warning value value, the data acquisition system sends out an alarm signal. The present invention also provides a method for testing the fire resistance capability of pipelines corresponding to the above-mentioned device.

Description

technical field [0001] The invention mainly relates to a pipeline fire prevention capability test, in particular to a high-accuracy, high-safety pipeline fire prevention capability test device and method. Background technique [0002] The fire resistance rating refers to the ability of components to maintain their original functions when exposed to a heat field or other specific environment and withstand a flame temperature of 1000-1200 ° C for about 5 minutes or 15 minutes. [0003] In the field of aero engines, the external pipelines of the engine used to transmit flammable liquids such as fuel oil and lubricating oil are located in areas where the engine may catch fire. Therefore, ensuring the fire protection of the external pipeline of the engine is an important part of the engine safety design, and verifying the fire prevention capability of the external pipeline of the engine is an important indicator. The pipeline fire test method stipulated in the existing aviation ...

Problems solved by technology

The pipeline fire test method stipulated in the existing aviation industry standard HB7044-94 "Fire Test of Hose and Hard Pipe Components" only specifies the burner equipment and test environment, and does not specify the test items and tests. The method is clearly stipulated, and the test result can only be judged by visually observing whether there is a crack or leakage / leakage during the test. If there is a crack or leakage / leakage, the test fails

Such a test verification method is highly subjective and lacks data support, and the test results must be observed after the pipeline ruptures or leaks / leakage occurs
