主要用途

回彈性(xing)優良的金(jin)屬纏繞墊(dian)片能夠對管(guan)道系統的壓力熱循(xun)環和振動(dong)進行

自動調整，特別適用于(yu)負荷不均勻(yun)、接合力(li)(li)(li)易松(song)弛，溫(wen)度與(yu)壓力(li)(li)(li)周期性(xing)變化、有沖(chong)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(guang)泛地用于(yu)石化、機械、電力(li)(li)(li)、冶(ye)金、造船、醫藥、原子能和宇航等部門。

在法(fa)蘭墊(dian)外觀設(she)計上(shang)為(wei)了(le)安(an)(an)裝方便,根據墊(dian)片口徑大小,在墊(dian)片外圍焊上(shang)2~8個定位帶,讓(rang)定位帶扣(kou)在法(fa)蘭孔(kong)上(shang),以防(fang)安(an)(an)裝時(shi)墊(dian)片移位或脫落,節約了(le)輔助(zhu)材料及工時(shi).一(yi)般(ban)分為(wei)以下幾種(zhong)類(lei)型:

金(jin)屬(shu)(shu)纏(chan)繞墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)采(cai)用(yong)優質SUS304、SUS316("V"形或(huo)"W"形) 金(jin)屬(shu)(shu)帶及(ji)其(qi)它合金(jin)材料(liao)與石墨、石棉(mian)、聚四(si)氟乙(yi)烯墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)、無石棉(mian)等軟性(xing)材料(liao)相互(hu)交替重疊螺旋纏(chan)繞而(er)成，在開始及(ji)末端用(yong)點焊方式將金(jin)屬(shu)(shu)帶固(gu)定。金(jin)屬(shu)(shu)纏(chan)繞墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)為(wei)半金(jin)屬(shu)(shu)密合墊(dian)(dian)(dian)中(zhong)回(hui)彈性(xing)墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)，金(jin)屬(shu)(shu)纏(chan)繞墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)結構密度(du)可依據(ju)不(bu)(bu)同的(de)鎖(suo)緊力要(yao)求(qiu)來(lai)(lai)制作，并利用(yong)內外鋼環來(lai)(lai)控制其(qi)zui大壓緊度(du)，纏(chan)繞墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)接(jie)觸的(de)法(fa)蘭密封面的(de)表面精度(du)要(yao)求(qiu)不(bu)(bu)高。金(jin)屬(shu)(shu)纏(chan)繞墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)特(te)別適用(yong)于(yu)負荷不(bu)(bu)均勻、接(jie)合力易松弛，溫度(du)與壓力周期性(xing)變化、有沖擊或(huo)震動的(de)場合。纏(chan)繞墊(dian)(dian)(dian)片(pian)(pian)(pian)(pian)是閥門、泵(beng)、換熱(re)器(qi)、塔、人(ren)孔、手(shou)孔等法(fa)蘭連接(jie)處理想的(de)靜密封原(yuan)件。

纏繞墊片應用范圍:

石(shi)油、化工、冶金、電(dian)力、船舶、機械等(deng)行業的(de)管道(dao)、閥門、壓力容器、冷(leng)凝器、換熱器、塔、人孔、手(shou)孔等(deng)法蘭(lan)連(lian)接處密(mi)封。
