Leave a comment

Producdt Description

In Line Flame Arrester is mainly composed of shell and fire element. There are two kinds of commonly used metal mesh filter element and corrugated filter element. The metal mesh filter element is composed of stainless steel or copper mesh with a diameter of 0.23-0.315 mm and overlapping layers. In Line Flame Arrester in China usually use 16-22 mesh metal mesh with 4-12 layers.

The corrugated filter element is supported by stainless steel, copper-nickel alloy, aluminium or aluminium alloy. Corrugated flame retardant can prevent the fierce flame of deflagration, and can withstand the corresponding mechanical and thermal effects, flow resistance is small, easy to clean and replace.

Installation:

  1. Remove all flange cover and discard all packaging materials.
  2. Check the seat, the matching flange gasket on the seat surface. It must be clean, flat, scratch-free, corrosion-resistant, tool traces.
  3. Check the gasket to ensure that the material is suitable forapplication.
  4. Lubricate all studs and nuts with proper thread lubricant. If the fastener is a high temperature stainless steel material, a back-grabbing compound, such as molybdenum disulfide, is used.
  5. Inside gasket of bolt ring.
  6. Installing flange of Inline flame arrester shell to butt with flange of pipeline, attention should be paid to the position of lifting handle and top nut of In line flame arrester element to facilitate the removal of In line flame arrester elements in the future.

      Tank fire arrestor overview:

      1, storage tank explosion proof corrugated flame arrester type ZHQ-CZ is to prevent external flame there is flammable gas fleeing into the equipment or prevent the spread of flame in the equipment room. Tank explosion proof corrugated flame arrester is application by narrow pore heat conductor, because the heat loss and out of the principle design and manufacturing.
      Tank explosion proof corrugated flame arrester fire resistant layer structure have gravel type, type or corrugated metal screen type.

      2, storage tank explosion proof corrugated flame arrester type ZHQ-CZ is one type of the flame arrester, is introducing advanced technique of similar foreign products, and in accordance with the actual situation of domestic and China design and production of replacement products, safety equipment for oil storage tank, used to prevent flammable gas, liquid and prevent the spread of the flames and explosions caused by tempering. The flame arrester is fire resistant layer commonly used stainless steel or copper nickel alloy material pressed into corrugated, corrugated is decided by the size of the gas properties and prevent the flame speed. The working principle of the flame arrester, at present, there are mainly two kinds of Views: one is based on heat transfer is based on a wall effect. Pipeline explosion-proof crimped fire arrester type ZHQ-CZ is the application of the flame through the narrow pore heat conductor, explosion-proof fire retardant corrugated metal core formed of triangular elements to damage due to flame, the heat loss and out of the principle design and manufacture. Tank explosion proof corrugated flame arrester is mainly composed of two parts of the shell and the fire board. Hous. Housing should have enough strength, the shock pressure explosion. Fierce flame corrugated type arrester to prevent deflagration, and can withstand the mechanical and thermal effects of the corresponding, small flow resistance, easy cleaning and replacement. Corrugated type fire retardant plate supported by stainless steel, copper nickel alloy, aluminum or aluminum alloy.
