美標(biāo)金屬纏繞墊尺寸

金屬纏繞墊片是應(yīng)用廣泛的一種密封墊片，為半金屬密合墊中回彈性佳的墊片，由V形或W形薄鋼帶與各種填充料交替纏繞而成，能耐高溫、高壓和適應(yīng)超低溫或真空下的條件使用，通過改變墊片的材料組合，可解決各種介質(zhì)對墊片的化學(xué)腐蝕問題，其結(jié)構(gòu)密度可依據(jù)不同的鎖緊力要求來制作，為加強主體和準(zhǔn)確定位，纏繞墊片設(shè)有金屬內(nèi)加強環(huán)和外定位環(huán)，利用內(nèi)外鋼環(huán)來控制其大壓緊度，對墊片接觸的法蘭密封面的表面精度要求不高。

回彈性優(yōu)良的金屬纏繞墊片能夠?qū)艿老到y(tǒng)的壓力熱循環(huán)和振動進(jìn)行

自動調(diào)整，特別適用于負(fù)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(yī)藥、原子能和宇航等部門。
