鋼(gang)(gang)包(bao)(bao)墊(dian)(dian)片(pian)(pian)系指內部用非金(jin)屬材料(liao)(柔(rou)性石(shi)墨(mo)(mo)聚(ju)四氟(fu)乙烯、石(shi)棉(mian)(mian)(mian)橡膠板 、 陶(tao)瓷纖維) 等(deng)(deng)， 外(wai)部用特定的冷作工藝包(bao)(bao)覆(fu)金(jin)屬薄(bo)板的復合型墊(dian)(dian)片(pian)(pian)，按墊(dian)(dian)片(pian)(pian)截面(mian)(mian)通常分(fen)為平面(mian)(mian)型包(bao)(bao)覆(fu)及(ji)波紋型包(bao)(bao)覆(fu)兩種，是的一(yi)種密合墊(dian)(dian)片(pian)(pian)，適(shi)用于熱交換器、壓(ya)力容器、泵、閥及(ji)法蘭面(mian)(mian)密封。但回彈力有(you)限，需要求法蘭表面(mian)(mian)平坦及(ji)緊固力很高才(cai)能(neng)達到良好(hao)效(xiao)果。根據不(bu)(bu)同材料(liao)可(ke)以組合成(cheng)304不(bu)(bu)銹鋼(gang)(gang)包(bao)(bao)石(shi)棉(mian)(mian)(mian)包(bao)(bao)覆(fu)墊(dian)(dian)片(pian)(pian)，不(bu)(bu)銹鋼(gang)(gang)包(bao)(bao)石(shi)墨(mo)(mo)包(bao)(bao)覆(fu)墊(dian)(dian)片(pian)(pian)等(deng)(deng)多種形式。鋼(gang)(gang)包(bao)(bao)墊(dian)(dian)片(pian)(pian)以柔(rou)性石(shi)墨(mo)(mo)、陶(tao)瓷纖維、石(shi)棉(mian)(mian)(mian)及(ji)無(wu)石(shi)棉(mian)(mian)(mian)板作為填充，外(wai)包(bao)(bao)不(bu)(bu)銹鋼(gang)(gang)、馬(ma)口鐵、紫銅等(deng)(deng)各種材質(zhi)的金(jin)屬薄(bo)板而成(cheng)，特別適(shi)用熱交換器、壓(ya)力容器等(deng)(deng)高溫高壓(ya)密封部位。它有(you)效(xiao)防止(zhi)墊(dian)(dian)片(pian)(pian)的散架、介質(zhi)的侵蝕，同時(shi)也提高了(le)耐壓(ya)。

材質及結(jie)構

1、包(bao)復(fu)料(liao):碳鋼(gang)(gang)、紫鋼(gang)(gang)、lCr18Ni9、304、316。 2、填充(chong)料(liao):石棉橡膠板、石墨(mo)板、非(fei)石棉板。 3、金(jin)屬(shu)與非(fei)金(jin)屬(shu)板包(bao)復(fu)壓制(zhi)成型(xing)。 主要用(yong)途:鋼(gang)(gang)包(bao)墊適(shi)用(yong)于(yu)機、泵、管、閥法(fa)蘭(lan)連接(jie)處的靜密封。
