外定位環金屬纏繞墊廠家

金屬纏繞墊片是應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，可解決各種介質對墊片的化學腐蝕問題，其結構密度可依據不同的鎖緊力要求來制作，為加強主體和準確定位，纏繞墊片設有金屬內加強環和外定位環，利用內外鋼環來控制其大壓緊度，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。
