Highlights \/ Outstanding Features \/ Characteristics<\/h2>\n
    \n
  1. The conical section shall be made of 310 stainless steel or a similar corrosion-resistant and high-temperature-resistant metal.<\/li>\n
  2. The vibration source is composed of an electric motor and a belt-driven eccentric wheel Amplitude \u00b159mm, Frequency: 33Hz, with an error margin of \u00b12% for both amplitude and frequency.<\/li>\n<\/ol>\n

    Test Methods \/ Procedures<\/h2>\n

    This test simulates the capability of piping components to maintain system integrity under extreme aircraft fire conditions. Strictly adhering to airworthiness standards, the specimen is subjected to direct ablation from a standard flame at 1100\u00b180\u2103 under dynamic operating conditions involving specified pressure, flow rate, and simulated vibration. By continuously monitoring the component’s sealing performance within the stipulated duration (5 minutes for fire resistance rating or 15 minutes for fire protection rating), the test validates its reliability in delaying failure and preventing fire propagation during a fire emergency.<\/p>\n

    Specifications<\/h2>\n

      Brief Introduction<\/h2>\n

      This test is applicable to the fire resistance testing of hose and tubing assemblies used in civil aircraft, including convoluted hoses, tubing connections, and hose assemblies protected with protective sleeves. Its purpose is to evaluate the fire resistance of hose and tubing assemblies installed in potential fire zones for conveying combustible fluids, in order to verify that the assemblies meet the fire resistance requirements specified in the applicable specifications.<\/p>","protected":false},"featured_media":624,"template":"","meta":{"_acf_changed":false},"product_brand":[20],"product_cat":[18,156],"product_tag":[],"class_list":["post-623","product","type-product","status-publish","has-post-thumbnail","product_brand-zonsky","product_cat-all-product","product_cat-far-aviation","first","instock","shipping-taxable","product-type-simple"],"acf":[],"aioseo_notices":[],"aioseo_head":"\n\t\t\n\t\n\t\n\t\n\t\n\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t\n\t\t
