Abstract

The invention discloses a fire resistance test system for a pipeline connecting piece. The fire resistance test system comprises the pipeline connecting piece (10) as a test piece, the water inlet atthe right end of the pipeline connecting piece is communicated with one end of a water inlet pipeline (101), and the other end of the water inlet pipeline is communicated with the water outlet of a circulating water pump (7); the water outlet at the left end of the pipeline connecting piece is communicated with one end of a water outlet pipeline (102), the other end of the water outlet pipeline iscommunicated with the water inlet of the circulating water pump, and a second temperature sensor (2) is mounted on the water inlet pipeline (101); a first temperature sensor (1) is mounted on the water outlet pipeline, a water pressure gauge (3) is mounted on the water inlet pipeline connected with the water outlet of the circulating water pump, and a plurality of carbon arc lamps (5) are arranged beside the pipeline connecting piece at intervals. According to the system, the carbon arc lamps are used for heating the whole pipeline connecting piece, so that the bearing state of the pipeline connecting piece can be truly simulated when a ship body is on fire, and the reliability and stability of the pipeline connecting piece are assessed.

Description

technical field [0001] The invention relates to the technical field of fire resistance tests in the shipbuilding industry, in particular to a fire resistance test system for pipeline connectors. Background technique [0002] The fire resistance test of the hull pipeline connector is to simulate the safety of the hull pipeline connector in a fire state, and to improve the product through assessment to ensure the reliability and stability of the product during use. [0003] The design of the fire resistance test system of the hull piping connector must comply with GB / T22218-2008 "Test method for fire resistance of metal piping accessories equipped with elastic seals for ship and offshore technology" and GB / T22219-2008 "ship and Requirements for Fire Resistance Performance Test Bench of Metal Pipeline Accessories Equipped with Elastic Seals". [0004] For the existing fire resistance test plan of the hull pipeline connectors, it uses real fire to simulate the fire of the hull,...
