          SHJ—GSW系列金屬纏繞式墊片
          材質結構及特點:
                  纏繞式墊片是在胎具上用“V”或“W”型各種金屬帶加各種軟填料,并在施加一定的壓力和繞緊力的狀態下,用專用機械加工而成,始末端點焊數點,所以墊片結構牢固,在振動的情況下也不易散開,為保護墊片本體,增加使用壓力,還在墊片的內徑或外徑分別加上內定心環或外定心環或同時加上內外定心環,這樣安裝時易于定位,并起到防止過量壓縮的作用。該產品具有機械強度大,耐熱性高,不滲透性能好,使用壽命長等優異特點。本產品執行中石化總公司、國際、及一機部、化工部、石油部標準。
          流體介質:
                  適用于溫度在800℃以下,壓力在25MPA以下,以水、飽和蒸汽、過熱蒸汽、油品、油氣、酸、堿、溶劑、氫氣、高壓氮氣、催化劑和催化煙氣等為介質的壓力容器法蘭、管法蘭連接處的密封。

          SHJ-GSW SERIES METAL WINDING TYPE PACKING SHEET
          Composition and characteristics:
             The winding type packing sheet is made from metal strip and soft packings. It is manufactured by special-purpose machines under certain pressure and winding force while the V or W shaped metal strip and the packing are placed in the shaping tools. At the beginning and end positions,several points are welded by spot welding. Therefore, the packing sheet has firm structure and is not easy to spread out under the condition of shock. In order to protect the sheet proper and increase the working pressure, the internal dcentring ring and/or extemal centring ring are /is equipped at the inner /outside diameter(s) of the sheet to that it is easy to place when assembling and extreme compression can be prevented. The product features high mechanical strength and resistance to heat, good resistance to permeation, and long service life.
