3.內(nèi)外環(huán)材料
常用的有304SS,316LSS,321SS,347SS,碳鋼,鈦,銅.
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
A strip: 0 Cr13, 0Cr18Ni9 (304), 0Cr18Ni9Ti, 1Cr18Ni9Ti (321), 0Cr17Ni12Mo2 (316), 00Cr17Ni14Mo2 (316L)
B, both inside and outside ring materials are A3, 304,316,316 L
C, non-metallic sandwich belt: Flexible Graphite PTFE, custom-made asbestos
