LFTA650 Explosive Disc with Arch Opening for Exhaust Gas Treatment

LFTA650 Explosive Disc with Arch Opening for Exhaust Gas TreatmentThe concave surface is located on the high-pressure side of the pressure system. A bursting disc consists of two or more layers, with one layer being a sealing film and at least one layer being a positively arched bursting disc with holes (seams). The positive arch slotted blasting disc is a new structure designed to solve the production difficulties caused by low blasting pressure or small discharge diameter. In order to seal it, a sealing membrane must be added. Due to the limitations of temperature and pressure on the sealing membrane material, the applicability of the positive arch slotted blasting disc is restricted.

Product Description:

A combination explosive disc is composed of components such as a strength film and a sealing film, and an additional layer of support is required for situations where back pressure needs to be withstood. There are holes and seams (radial or circumferential seams) on the strength film and bracket that weaken the strength of the material. When subjected to overpressure, it will break under tension at the section with the minimum hole spacing.

Characteristics of positive arch slotted blasting disc (LF)

1. Suitable for both gas and liquid media, as well as medium and low-pressure burst pressure conditions

2. When selecting a sealing film, consideration should be given to its temperature range of applicability

3. The maximum working pressure can reach 80% of the minimum burst pressure

4. Fragments may be generated during blasting, and it is not recommended to use them in series with safety valves

5. Large caliber LF type blasting discs can achieve very low blasting pressure and are suitable for dust release and explosion suppression occasions

6. The product code without bracket is LF, and the product code with bracket is LFT

7. The product nameplate has TS

8. Size: DN10~DN1200mm

Performance and characteristics of commonly used materials for blasting discs

Due to the fact that chemical equipment or containers used for installing explosive discs often operate continuously under high temperature and high pressure, or under pulsating cyclic pressure, or when the medium in contact with the explosive disc is highly corrosive, it is necessary to fully consider the mechanical and chemical properties of the material when selecting the explosive disc. This not only requires the explosive disc to have a reasonable mechanical structure, accurate parameters, and high fatigue resistance, but also to have good corrosion resistance, high-temperature creep resistance, long-term tissue stability, and mechanical processing characteristics. Nowadays, the materials used to produce explosive discs include both metallic materials (including pure metals and alloys) and non-metallic materials, with a wide variety and grades. Some designers or users have a shallow understanding of the properties of the materials, leading to a great deal of blindness in material selection. And the analysis of the material of the Yuan blasting disc here reflects its inherent value. Only by clarifying the usage characteristics and conditions of various materials can designers and users choose suitable blasting discs in the application, thereby increasing the safety of the process and reducing the risk factor.
