石墨(mo)墊(dian)(dian)片(pian)以石墨(mo)線為材(cai)料(liao)，經編織而(er)成。石墨(mo)墊(dian)(dian)片(pian)適用(yong)于(yu)高(gao)溫、高(gao)壓、強(qiang)腐蝕(shi)性介質下(xia)工(gong)作的(de)(de)各類(lei)閥門(men)、泵、反應釜(fu)等(deng)設備(bei)的(de)(de)填料(liao)函密(mi)封。柔性石墨(mo)具有優良(liang)耐(nai)溫性（-260℃~+1500℃），耐(nai)腐蝕(shi)性，應力松(song)弛(chi)率(lv)小，其(qi)做成的(de)(de)密(mi)封件具有很(hen)好的(de)(de)密(mi)封性能。石墨(mo)復合墊(dian)(dian)是已經沖刺的(de)(de)金屬薄板為骨架(jia)，在其(qi)表面復合柔性石墨(mo)構成。石墨(mo)墊(dian)(dian)片(pian)用(yong)于(yu)各種(zhong)工(gong)業上(shang)的(de)(de)管道法(fa)蘭(lan)，換熱器，閥蓋(gai)等(deng)，以及(ji)液面計、水準儀上(shang)的(de)(de)特(te)殊(shu)形狀(zhuang)法(fa)蘭(lan)。

石墨墊片分類

柔性石(shi)墨(mo)墊片由柔性石(shi)墨(mo)薄片(或帶(dai)有(you)金屬加強)切割(ge)而成，根據(ju)應(ying)用需要共分為四種類型:

1、柔性石墨墊片(pian):從(cong)柔性石墨薄(bo)片(pian)上切(qie)割而成(cheng)，用于管道法蘭和閥蓋等。建議這種墊片(pian)都為(wei)小(xiao)直徑墊片(pian)，這取決于它的低機(ji)械強度。

2、柔(rou)性(xing)石(shi)(shi)墨(mo)墊片(pian)MI:帶鉤的碳鋼薄(bo)片(pian)(0.2毫米(mi)厚)被柔(rou)性(xing)石(shi)(shi)墨(mo)薄(bo)片(pian)夾在中間，然后被切割成(cheng)特定的尺寸，機械(xie)強度很(hen)高。

3、柔(rou)(rou)性石(shi)墨墊(dian)片(pian)PM:柔(rou)(rou)性石(shi)墨薄片(pian)被(bei)(bei)粘附(fu)在0.2毫米(mi)厚的(de)(de)304不銹(xiu)鋼(gang)薄片(pian)的(de)(de)兩面，具有(you)很(hen)高的(de)(de)機械(xie)強(qiang)度并且(qie)易(yi)于(yu)(yu)運輸，由于(yu)(yu)它也可(ke)以(yi)被(bei)(bei)切割(ge)成復(fu)雜的(de)(de)形(xing)狀，這種墊(dian)片(pian)被(bei)(bei)廣泛的(de)(de)應用在各種工業中。

4、 柔性石墨墊(dian)片(pian)PM-A:將(jiang)T/#1215 中的不銹鋼薄(bo)片(pian)換成(cheng) 316鋼(50 微(wei)米)。

包邊石墨(mo)(mo)墊(dian)(dian)片(pian)是對(dui)純切割石墨(mo)(mo)墊(dian)(dian)片(pian)的改進，內外圈包覆金(jin)屬薄片(pian)，即保(bao)持原有墊(dian)(dian)片(pian)的各項(xiang)優異(yi)性能，又便(bian)于(yu)安裝、拆卸(xie)，不(bu)銹鋼石墨(mo)(mo)墊(dian)(dian)片(pian)價(jia)格，不(bu)易損壞，同時(shi)也(ye)可(ke)以防止介質對(dui)墊(dian)(dian)片(pian)的侵(qin)蝕，提高了耐壓。常用(yong)包邊材料為304或316不(bu)銹鋼。可(ke)使用(yong)壓力(li)6.4~10Mpa。

石墨墊(dian)片性(xing)能特(te)點：它具有(you)良好的(de)防腐蝕性(xing)， 耐高(gao)/低溫，耐輻射，良好的(de)壓縮(suo)回彈性(xing)和高(gao)強度性(xing)，所(suo)需的(de)預緊力比金(jin)(jin)屬墊(dian)片和金(jin)(jin)屬纏繞墊(dian)片要小，對法蘭(lan)面的(de)要求不(bu)高(gao)，是一種比較經濟實用的(de)墊(dian)片。如(ru)果采用包邊形式可保(bao)持(chi)原有(you)石墨復合墊(dian)片的(de)各項優異性(xing)能，又便于安裝、拆卸，不(bu)易損壞，同(tong)時也可防止介質(zhi)和外界空(kong)氣(qi)中氧(yang)氣(qi)對墊(dian)片的(de)侵蝕，提高(gao)了耐溫和耐壓性(xing)能。

石(shi)墨墊片(pian)(pian)使用設備(bei)： 管道(dao)、閥門(men)、泵、壓力容器、熱(re)交換器、冷凝(ning)器、發電(dian)機(ji)、空氣壓縮機(ji)、排(pai)氣管、制(zhi)冷機(ji)等法蘭連(lian)接(jie)處的密封部位可替代石(shi)棉橡膠(jiao)墊片(pian)(pian)、鐵包(bao)墊片(pian)(pian)。 石(shi)墨復合墊片(pian)(pian)最da加工(gong)尺寸無限制(zhi)， 特殊規格或各類非(fei)標準(zhun)產品可按(an)客戶要求制(zhi)定。
