To prepare for prohibition of asbestos products, a verification test was made to select asbestos free spiral wound gasket (SWG) for high-temperature and oxidative condition. Since cracked gas from naphtha cracker of ethylene production plant is over 600°C, asbestos filled SWG was formerly installed in the flanges for this facility. To select substituted gasket free from asbestos, the following gaskets were installed in flanges of actual naphtha cracker: (1) vermiculite filled SWG, (2) mica-graphite filled SWG which was recommended by a gasket manufacturer, (3) asbestos-graphite filled SWG for comparison. After three times of start-stop cycle of the plant operation in near one year, vermiculite filled SWG did not change in its appearance and showed better seal ability than other two gaskets. Mica-graphite SWG could not resist naphtha cracker environment because exfoliated graphite filler was disappeared with oxidative degradation within several months. Vermiculite filled SWG showed higher reliability than mica-graphite filled SWG in the verification test, hence this SWG is expected to have a 2-year durability that is required for the ethylene production plant.
