Internal and external ring winding gasket is by the metal belt and nonmetal with spiral compound around from the system of a kind of half a metal flat washers. Has good compression, recovery, not binding flange surface, thus disassembling seal convenient. Can partly eliminate the pressure, temperature and the influence of mechanical vibration; In high temperature, low temperature, high vacuum, impact and vibration ambient conditions, to keep the good seal performance. Applicable equipment: all kinds of pipe, valve, pressure vessel, condenser, heat exchanger, tower, manhole, hand hole, process piping static sealing parts. Applicable industries: oil refining, petroleum chemical industry, metallurgy, electric power, gas, nuclear energy, space, textile, medicine, shipping, machinery, etc. Inside and outside ring winding pads the largest machining size: 3000 mm; Special specifications or all kinds of non-standard customers can request the formulation. Internal and external ring winding pads the filling materials: fill material with the inner ring steel material asbestos SUS 304 carbon steel carbon steel graphite SUS 316 SUS 304 SUS 304 four fluorine SUS 316 L SUS 316 SUS 316 more detail information please visit: http://www.bt-lj.com HeJian strong sealing material Co., LTD
