Status of Sampling Testing of Ethylene Pyrolysis Furnace Tubes in China
摘要
Abstract
Sampling test status of ethylene pyrolysis furnace tubes is summed up by Sinopec Inspection and Assessment Center on Furnace Tube (SIACFT) in recent two years.Chemical composition test,ten-sile test at room temperature and high -temperature stress rupture test of furnace tubes and fittings was carried out respectively on 141 pieces of centrifugal casting furnace tubes ,24 pieces of welding joints and 27 pieces of static casting fittings .The status of impurity value in furnace tube industry ,tensile properties at room temperature and high -temperature stress rupture life of furnace tubes and fittings are summa-rized.The results revealed a serious situation of furnace tube industry that 80%~90%centrifugal casting furnace tubes are qualified ,while all of the welding joints and static casting fittings are unqualified .Impu-rity control,the relationship between newly manufactured furnace tubes and fittings performance and serv-iced furnace tube failure mode are also discussed .关键词
