Generally the material of the inner ring is steel belt, to satisfy the medium and the working condition demands,
The outer ring material is the same as the pipe and the related equipment shell, the carbon steel outer ring is relatively economic.
The detailed order should indicate the detailed material, the used standard, the inside exhaust pipe nominal diameter DN, the pressure grade PN, or indicate the detailed size:
D1:inner diameter of the inner ring;D2: outer diameter of the inner ring;
D3:inner diameter of the outer ring;D4: outer diameter of the outer ring
Writing methods:D1×D2×D3×D4
The default thickness of the gasket is 4.5mm,and the ring 3mm
