Product Overview




Ordinary blasting disc with normal arch


Blasting pressure of normal blasting disc is mainly determined by tensile strength of blasting disc material. When working, the system pressure acts on the concave surface of the arch shell of the blasting disc. When the protected system overpressures, the blasting elements are biaxially stretched, plastic deformation occurs, the wall thickness is thinned, and eventually ruptures, releasing pressure, thus playing the role of protecting the system.

Normal Arch Blasting Disc (LP): Used in conjunction with gripper, it is suitable for situations where it can withstand back pressure or has no back pressure and vacuum.


Technical characteristics:


♦ It can be used in a wide range, and the corresponding assembly structure can be selected according to different blasting pressure and discharge caliber.

♦ The range of pressure processing is limited by material strength.

♦ It is suitable for gas and liquid media.

♦ It is suitable for high temperature and high pressure environment.

♦ The maximum working pressure should not exceed 70% of the minimum blasting pressure, which is not suitable for pressure fluctuation.

♦ There was debris after the blasting.

♦ The service life is short, the stress level of the blasting disc is high, and the creep deformation and fatigue failure are easy to occur.

♦ Temperature effect is obvious. When the temperature rises, the blasting pressure will decrease obviously, and the blasting pressure will fluctuate with the temperature fluctuation.
