鋼(gang)包墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)系指(zhi)內部用(yong)(yong)非金(jin)屬材料(liao)(柔(rou)性石墨(mo)聚(ju)四(si)氟乙烯(xi)、石棉橡膠(jiao)板(ban) 、 陶(tao)瓷纖維) 等， 外部用(yong)(yong)特定的(de)冷作(zuo)工藝包覆(fu)金(jin)屬薄板(ban)的(de)復合(he)(he)型墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)，按墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)截面(mian)通常分為平(ping)面(mian)型包覆(fu)及(ji)波紋(wen)型包覆(fu)兩種，是(shi)的(de)一種密(mi)合(he)(he)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)，適(shi)用(yong)(yong)于(yu)熱交換器(qi)、壓(ya)力(li)容器(qi)、泵(beng)、閥及(ji)法蘭面(mian)密(mi)封(feng)。但回彈力(li)有(you)限，需要求法蘭表面(mian)平(ping)坦(tan)及(ji)緊固力(li)很高才(cai)能達到良(liang)好效果。根據(ju)不(bu)(bu)同材料(liao)可(ke)以組(zu)合(he)(he)成304不(bu)(bu)銹鋼(gang)包石棉包覆(fu)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)，不(bu)(bu)銹鋼(gang)包石墨(mo)包覆(fu)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)等多種形式。鋼(gang)包墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)以柔(rou)性石墨(mo)、陶(tao)瓷纖維、石棉及(ji)無石棉板(ban)作(zuo)為填充，外包不(bu)(bu)銹鋼(gang)、馬口鐵、紫銅等各(ge)種材質(zhi)的(de)金(jin)屬薄板(ban)而成，特別適(shi)用(yong)(yong)熱交換器(qi)、壓(ya)力(li)容器(qi)等高溫高壓(ya)密(mi)封(feng)部位。它有(you)效防止墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)的(de)散(san)架、介質(zhi)的(de)侵蝕，同時也提(ti)高了耐壓(ya)。
