鋼包(bao)(bao)墊(dian)(dian)(dian)(dian)片(pian)系指內(nei)部(bu)用非金屬(shu)材(cai)料(liao)(柔性石墨聚四氟乙烯、石棉橡膠(jiao)板 、 陶瓷(ci)纖(xian)維) 等(deng)， 外(wai)部(bu)用特定的(de)(de)冷作(zuo)工藝包(bao)(bao)覆(fu)(fu)金屬(shu)薄板的(de)(de)復合型(xing)墊(dian)(dian)(dian)(dian)片(pian)，按墊(dian)(dian)(dian)(dian)片(pian)截面通常分為平(ping)面型(xing)包(bao)(bao)覆(fu)(fu)及波紋型(xing)包(bao)(bao)覆(fu)(fu)兩種(zhong)，是的(de)(de)一種(zhong)密(mi)合墊(dian)(dian)(dian)(dian)片(pian)，適用于熱交換器(qi)、壓力(li)容器(qi)、泵、閥及法蘭面密(mi)封(feng)。但回彈(dan)力(li)有限，需要求法蘭表(biao)面平(ping)坦及緊(jin)固(gu)力(li)很高(gao)才能達(da)到(dao)良好效果。根據不(bu)同材(cai)料(liao)可以組(zu)合成304不(bu)銹鋼包(bao)(bao)石棉包(bao)(bao)覆(fu)(fu)墊(dian)(dian)(dian)(dian)片(pian)，不(bu)銹鋼包(bao)(bao)石墨包(bao)(bao)覆(fu)(fu)墊(dian)(dian)(dian)(dian)片(pian)等(deng)多(duo)種(zhong)形式。鋼包(bao)(bao)墊(dian)(dian)(dian)(dian)片(pian)以柔性石墨、陶瓷(ci)纖(xian)維、石棉及無石棉板作(zuo)為填充，外(wai)包(bao)(bao)不(bu)銹鋼、馬口鐵、紫銅等(deng)各(ge)種(zhong)材(cai)質(zhi)的(de)(de)金屬(shu)薄板而成，特別適用熱交換器(qi)、壓力(li)容器(qi)等(deng)高(gao)溫高(gao)壓密(mi)封(feng)部(bu)位。它(ta)有效防止墊(dian)(dian)(dian)(dian)片(pian)的(de)(de)散架、介質(zhi)的(de)(de)侵蝕，同時也(ye)提(ti)高(gao)了耐(nai)壓。

材質(zhi)及結構(gou)

1、包復料(liao):碳鋼、紫鋼、lCr18Ni9、304、316。 2、填(tian)充料(liao):石棉橡膠板(ban)、石墨板(ban)、非石棉板(ban)。 3、金屬與非金屬板(ban)包復壓(ya)制成(cheng)型(xing)。 主(zhu)要用(yong)途:鋼包墊適用(yong)于(yu)機、泵、管(guan)、閥法蘭連接(jie)處的靜密封(feng)。
