石墨墊片特點和分類

石(shi)(shi)墨(mo)墊片以(yi)石(shi)(shi)墨(mo)線為(wei)材料,經(jing)編(bian)織而成。石(shi)(shi)墨(mo)墊片適用于(yu)高溫(wen)、高壓(ya)、強(qiang)腐蝕性(xing)(xing)介(jie)質下(xia)工作的各類閥門(men)、泵(beng)、反應釜等設備(bei)的填料函密封(feng)。柔(rou)性(xing)(xing)石(shi)(shi)墨(mo)具有優良(liang)耐(nai)溫(wen)性(xing)(xing)(-260℃~+1500℃),耐(nai)腐蝕性(xing)(xing),應力松(song)弛率小(xiao),其做成的密封(feng)件具有很好的密封(feng)性(xing)(xing)能(neng)。石(shi)(shi)墨(mo)復合(he)(he)墊是已經(jing)沖刺的金屬(shu)薄(bo)板為(wei)骨架(jia),在其表面復合(he)(he)柔(rou)性(xing)(xing)石(shi)(shi)墨(mo)構成。石(shi)(shi)墨(mo)墊片用于(yu)各種工業上的管道法(fa)蘭(lan),換(huan)熱器,閥蓋等,以(yi)及液面計、水準儀上的特殊形(xing)狀(zhuang)法(fa)蘭(lan)。

 

石墨墊片分類

柔性(xing)石墨(mo)墊(dian)片由柔性(xing)石墨(mo)薄(bo)片(或帶有金屬(shu)加強)切割而成,根據應用需(xu)要共(gong)分為(wei)四(si)種類(lei)型(xing):

1、柔(rou)性(xing)石墨墊(dian)片:從柔(rou)性(xing)石墨薄(bo)片上切割而成,用于管道法蘭和閥蓋等。建議這種墊(dian)片都為小直(zhi)徑墊(dian)片,這取(qu)決于它的低機械強度。

2、柔性石墨墊片MI:帶鉤的碳鋼薄(bo)片(0.2毫(hao)米厚)被柔性石墨薄(bo)片夾在中間,然后被切(qie)割成特定(ding)的尺寸,機械強(qiang)度很高。

3、柔性石(shi)墨墊片PM:柔性石(shi)墨薄片被粘附在0.2毫米厚的(de)(de)304不銹(xiu)鋼薄片的(de)(de)兩面,具(ju)有(you)很高的(de)(de)機械強度并(bing)且易于(yu)運(yun)輸,由于(yu)它(ta)也可以被切割成復雜的(de)(de)形(xing)狀(zhuang),這種墊片被廣泛的(de)(de)應(ying)用在各種工業中。

4、 柔性石墨墊片(pian)(pian)PM-A:將T/#1215 中的(de)不銹鋼(gang)薄片(pian)(pian)換成 316鋼(gang)(50 微米)。

包邊(bian)石墨墊片(pian)(pian)是對純切割石墨墊片(pian)(pian)的(de)改進,內外圈包覆金屬(shu)薄片(pian)(pian),即保(bao)持(chi)原有(you)墊片(pian)(pian)的(de)各項優異性能,又便于安裝、拆卸,不(bu)(bu)銹鋼石墨墊片(pian)(pian)價格,不(bu)(bu)易損壞,同時也可(ke)以防止介質對墊片(pian)(pian)的(de)侵蝕,提(ti)高了耐壓。常用(yong)包邊(bian)材料為304或316不(bu)(bu)銹鋼。可(ke)使用(yong)壓力6.4~10Mpa。

石墨墊(dian)(dian)片(pian)(pian)(pian)性(xing)(xing)能(neng)特(te)點:它具有良好的(de)(de)防腐蝕(shi)性(xing)(xing), 耐(nai)高(gao)(gao)/低溫,耐(nai)輻射(she),良好的(de)(de)壓縮回(hui)彈(dan)性(xing)(xing)和高(gao)(gao)強度性(xing)(xing),所需(xu)的(de)(de)預(yu)緊(jin)力比(bi)金屬墊(dian)(dian)片(pian)(pian)(pian)和金屬纏繞墊(dian)(dian)片(pian)(pian)(pian)要小,對法蘭面(mian)的(de)(de)要求不高(gao)(gao),是一種(zhong)比(bi)較經(jing)濟實用(yong)的(de)(de)墊(dian)(dian)片(pian)(pian)(pian)。如果采用(yong)包邊形式可保持(chi)原有石墨復合墊(dian)(dian)片(pian)(pian)(pian)的(de)(de)各項優異性(xing)(xing)能(neng),又便于(yu)安(an)裝(zhuang)、拆卸,不易損壞(huai),同時也可防止(zhi)介質和外(wai)界空(kong)氣(qi)中氧氣(qi)對墊(dian)(dian)片(pian)(pian)(pian)的(de)(de)侵蝕(shi),提(ti)高(gao)(gao)了耐(nai)溫和耐(nai)壓性(xing)(xing)能(neng)。

石墨墊(dian)片(pian)使用設備(bei): 管道(dao)、閥門(men)、泵(beng)、壓力(li)容器、熱交換器、冷凝器、發(fa)電機、空氣(qi)壓縮機、排(pai)氣(qi)管、制冷機等法蘭連接處(chu)的密封部位可替代石棉橡膠墊(dian)片(pian)、鐵包墊(dian)片(pian)。 石墨復合(he)墊(dian)片(pian)最da加工(gong)尺寸無限制, 特殊規格或各類非標準產品(pin)可按(an)客戶要(yao)求制定。
