          GQD系列高強石墨墊片
          材質結構及特點:
                  GQD型系列墊片是將不銹鋼板(或其它金屬板材)與高碳石墨(含碳量99%以上)經特殊加工后,利用物理和化學兩種方法將它們有機的結合在一起,制成的一種具有鋼材強度的新型密封材料。該種材料具有良好的可塑性和填充性,對密封面的精度要求不高,安裝預緊力小,耐高低溫,耐腐蝕,耐輻照,是石油、化工、化肥、化纖、熱電等工業管道、閥門、壓力容器法蘭連接處首選的理想密封材料。
          流體介質:
                  水、飽和蒸汽、過熱蒸汽、油品、油氣、酸、堿、有機溶劑、化合物、混合物、催化劑等。

          GQD HIGH STRENGTH GRAPHITE PECKING PIECE WITH INSIDE AND OUTSIDE EDGE WRAPPED
          Composition and characteristics:
              GQD high strength graphite pecking piece is a new steel strength steeling which is specially made of stainless steel plate(or other metals plate)and High-carbon graphite(carbon content above 99%)in physicaol and chemical way.By the good characters of well plasticity,requiring low precision of sealing face,small pre-tightening force,high or low temperature resistance,corrosion resistance, irradiation proof,this materials are used to seal flange connection of pipe,valve and pressure vessel in petroleum,chemical industry,chemical fibre,chemical fertilizer,heat power industry etc.
          FLUID MEDIUM
              Water,saturated steam,overheated steam,oil,oil gas,acid,alkali,organic solvent,mixture,compound,catalyst,etc.
