Flat Blasting Disc with Groove
Flat blasting disc with groove is a kind of "cross" or annular weakening groove machined on one side of circular metal diaphragm. When the blasting pressure is reached, the blasting disc ruptures along the weakening groove. When PC blasting disc is directly clamped between flanges, sealing gaskets should be bonded on both sides of the blasting disc.
♦ Usually used in large diameter pipes with very low pressure, medium or high back pressure, debris-free occasions.
♦ It is suitable for gas, liquid and dust.
♦ The fatigue resistance is general, and it is not suitable for the occasion where the pressure fluctuation is large.
♦ The maximum working pressure can reach 80% of the minimum blasting pressure.
