1. Product introduction

Fire Arresting Matenal is one of the most important components of flame arrester. Flame arrester can effectively prevent the flame spread of flammable gas and liquid and prevent tempering and cause explosion. The flame retardant corrugated plates in such flame arresters are usually corrugated by pressing stainless steel strips or copper-nickel alloy materials. The size of the corrugations is determined by the nature of the gas and the flame retarding speed.

Fire Arresting Matenal is made up of corrugated plates around a certain size of the shaft plate. The diameter of the corrugated fire-resistant core and the shaft diameter are determined by the company. The parameters of the thickness, width, apex angle, peak height and peak spacing of the corrugated board used for winding the corrugated fire-retardant core are also determined by the company (the specific matters are determined according to the actual processing capacity). The corrugated board is made of a 304 stainless steel plate of a certain thickness. Where h is the wave height, λ is the wave pitch, δ is the corrugated plate thickness 0.1 mm, α is the apex angle 90°, and L is the corrugated strip width. The wave height h value is preferred to meet the conditions. If other processing conditions cannot meet the requirements set by the company, first ensure that the wave height h value meets the design conditions. The wave distance λ and the apex angle α satisfy one of them. In addition to the corrugated board thickness of 0.1mm,the apex angle is 90° and the material is 304.

Technical requirements for Fire Arresting Matenal:

Fire Arresting Matenal is made up of a corrugated plate around a shaft d having a diameter d, and a flat plate of the same thickness material should be sandwiched between the two corrugated plates. After the winding reaches the diameter of the corrugated fire-resistant core D, a five-turn flat plate is added to fix the joint by welding.

Product inspection: 

1. Corrugated belt inspection measurement corrugated belt wave height h, measuring wave distance λ, measuring corrugated belt width L, allowable deviation

2. Fire Arresting Matenal inspection and measurement Corrugation resistance core ******** wave height h, measuring wave distance λ, measuring corrugation resistance core diameter D, allowable deviation as shown in Table 2; Fire Arresting Matenal should not appear loose, corrugated fire The bottom surface of the core is guaranteed to be horizontal; the weld of the corrugated fire-resistant core shall be inspected, and the weld-through corrugated strip and the weld crack shall not occur.
