Overview: Stainless steel explosion-proof corrugated flame arrester core is one of the main components of explosion-proof flame arrester. Explosion proof flame arrester can effectively prevent the spread of flammable gas and liquid flames and prevent backfire from causing explosions. This type of flame arrester

The fire-resistant corrugated plate inside is commonly made of stainless steel strip or copper nickel alloy material pressed into a corrugated shape, and the size of the ripples is determined by the properties of the gas and the speed of flame prevention. There are two types of explosion-proof corrugated fire-resistant plates:

One is composed of corrugated thin plates and flat plates alternately wrapped around the central axis, forming a stack of fire-resistant layers with triangular pores. The other is composed of corrugated thin plate materials folded in two directions, with the corrugations separated between them

Separated into many small pores and channels, it provides a winding pathway for flames. The thickness of commonly used corrugated sheets is0.1~0.3mmBetween them, the height of the ripples is generally0.2mmThe0.3mmThe0.5

mmThe0.7mmand1.2mmWait, it should be determined based on the speed of flame prevention. The explosion-proof corrugated flame arrester plate is the internal component of the flame arrester, and the flame arrester disc is made of stainless steel strip wrapped around it.

The corrugated flame retardant core is made by winding a corrugated plate around a certain size of shaft, and the diameter of the corrugated flame retardant core and shaft diameter are determined by our company. Corrugated board used for winding corrugated flame retardant cores, with thickness, width, top angle, and peak height

And parameters such as peak spacing are also developed by our company(Specific matters will be determined based on actual processing capabilities).

Technical requirements for corrugated fire-resistant core: The corrugated fire-resistant core is made by winding the diameter of the corrugated plate around itdTo form the shaft, there should be a flat plate of the same thickness material sandwiched between the two layers of corrugated plates.
