Anti corrosion anti arch slotted YFA50 blasting disc

Anti corrosion anti arch slotted YFA50 blasting discIt consists of two or more layers, with one layer being a sealing film and the other layer being a serrated and pressure rod component. The arched convex surface is located on the high-pressure side of the pressure system. When the protected pressure bearing system is overpressure, the pressure rod element is subjected to unstable force, causing the combined sealing membrane to flip over. The sealing membrane is punctured by the serrations of the pressure rod element to release pressure, thereby protecting the pressure bearing equipment.

The material of the blasting disc safety device should have good corrosion resistance, uniform and stable mechanical properties, and thermal stability, and be able to meet the basic safety requirements of the protected pressure equipment.

The commonly used materials for explosive discs are allowed to use temperatures of 400 ℃ for austenitic stainless steel, 430 ℃ for Monel, 480 ℃ for Inconel and Hastelloy. The commonly used sealing film materials in explosive disc components should not exceed 200 ℃ for F46, 260 ℃ for F4, and 400 ℃ for aluminum. The allowable operating temperature for bursting discs with sealing membranes should be determined based on the overlapping temperature range between the sealing membrane material and the bursting disc material.

The materials used for blasting discs and clamps should comply with the corresponding standards or industry standards, and should have quality certification documents (including quality certificates and qualification certificates) provided by the material manufacturing unit. Before each use, they should be re inspected according to the corresponding material standards and design drawings, and can only be used after passing the inspection.

If the bursting disc is used in a corrosive environment and may cause leakage or premature failure of the bursting disc safety device, anti-corrosion treatment measures such as electroplating, spraying, or lining can be taken on the surface of the bursting disc or clamp to prevent corrosion failure of the bursting disc safety device.

The main types of products are:

1. The anti arch slotted blasting disc YF is used in conjunction with the clamp YJ.

2. Welding type bursting disc YFJ is a device that welds the bursting disc with a metal pressure ring or clamp as a whole, ensuring sealing, easy installation, and convenient use.

Technical features:

1. Suitable for gas phase media and gas-liquid phase media

2. Suitable for low-pressure environments

3. There were no sparks during the explosion

4. The operational ratio is 90%

5. After blasting, there are no fragments and it can be used in series with a safety valve

6. The product nameplate has TS identification

7. Size: DN15-DN900mm
