金(jin)屬纏(chan)繞(rao)墊(dian)片(pian)是目前應用(yong)廣泛的(de)(de)一(yi)種密(mi)(mi)封(feng)(feng)墊(dian)(dian)(dian)(dian)片(pian)(pian)(pian)，為(wei)半金屬(shu)(shu)密(mi)(mi)合(he)墊(dian)(dian)(dian)(dian)中回彈性墊(dian)(dian)(dian)(dian)片(pian)(pian)(pian)，由(you)V形或W形薄鋼帶與(yu)各種填充料交替纏(chan)繞(rao)而成，能耐高溫、高壓和(he)適(shi)應超低(di)溫或真空(kong)下的(de)(de)條件使用(yong)，通過改變金屬(shu)(shu)纏(chan)繞(rao)墊(dian)(dian)(dian)(dian)片(pian)(pian)(pian)的(de)(de)材料組(zu)合(he)，可解決(jue)各種介質(zhi)對墊(dian)(dian)(dian)(dian)片(pian)(pian)(pian)的(de)(de)化學(xue)腐蝕問題，金屬(shu)(shu)纏(chan)繞(rao)墊(dian)(dian)(dian)(dian)片(pian)(pian)(pian)結構密(mi)(mi)度(du)(du)可依據不(bu)同(tong)的(de)(de)鎖緊力(li)要求來(lai)(lai)制作(zuo)，為(wei)加(jia)強主體(ti)和(he)準確(que)定位，纏(chan)繞(rao)墊(dian)(dian)(dian)(dian)片(pian)(pian)(pian)設(she)有(you)金屬(shu)(shu)內(nei)加(jia)強環(huan)和(he)外(wai)定位環(huan)，利用(yong)內(nei)外(wai)鋼環(huan)來(lai)(lai)控制其(qi)zui大(da)壓緊度(du)(du)，對墊(dian)(dian)(dian)(dian)片(pian)(pian)(pian)接(jie)觸(chu)的(de)(de)法蘭密(mi)(mi)封(feng)(feng)面的(de)(de)表(biao)面精度(du)(du)要求不(bu)高。
主要用途：回彈性優良的金屬纏繞墊片能夠對管道系統的壓力熱循環和振動進行自動調整，特別適用于負荷不均勻、接合力易松弛，溫度與壓力周期性變化、有沖擊或震動的場合。是閥門、泵、換熱器、塔、人孔、手孔等法蘭連接處的靜密封原件，廣泛地用于石化、機械、電力、冶金、造船、醫藥、原子能和宇航等部門。 :
在金屬纏繞法蘭墊片外觀設計上為了安裝方便,根據墊片口徑大小,在墊片外圍焊上2~8個定位帶,讓定位帶扣在法蘭孔上,以防安裝時墊片移位或脫落,節約了輔助材料及工時一般分為以下幾種類型：
金屬纏繞墊(dian)片的種類：
(一)基本型金屬纏繞墊片
(二)帶外環金屬纏繞墊片
(三)帶內環金屬纏繞墊片
(四)帶內外環金屬纏繞墊片
(五)換熱器用(帶筋)金屬纏繞墊片
(六)異形金屬纏繞墊片
金(jin)屬纏繞(rao)墊(dian)片(基本型)采用優質SUS304、SUS316(“V”形或“W”形) 金屬帶及其它合金材料與石墨、石棉、聚四氟乙烯、無石棉等軟性材料相互重疊螺旋纏繞而成，在開始及末端用點焊方式將金屬帶固定。
