D2232四氟金属缠绕垫

缠绕垫片为半金属密合垫中回弹性佳的垫片，缠绕垫片结构密度可依据不同的锁紧力要求来制作，并利用内外钢环来控制其大压紧度，金属缠绕垫片接触的法兰密封面的表面精度要求不高。

缠绕垫片特别适用于负荷不均匀、接合力易松弛，温度与压力周期性变化、有冲击或震动的场合。缠绕垫片是阀门、泵、换热器、塔、人孔、手孔等法兰连接处理想的静密封原件。 项目 厚度(mm) 公差(mm) 垫片厚度 4.5, 3.2 +0.2

常用的有304SS,316LSS,321SS,347SS,碳钢,钛,铜.

mix:

The flange on the pad designs to facilitate the installation of the Company under the gasket-caliber size, the gasket external welding a 2 ~ 8 positioning belt buckle for positioning hole in the flange, to prevent displacement installation gasket or falling out of the supporting material and saving hours of work.

Types and gasket materials

1, Winding pads divided into four forms: that is, as the basic type A, B band strengthen ring, the C-band to strengthen the ring, the D-band, the strengthening ring.

2, the general use of materials
