Technical Field
The utility model belongs to the technical field of the petroleum and petrochemical industry fire operation kit technique and specifically relates to a fire construction isolation protection blind plate.
Background
In the production operation process of petroleum and petrochemical enterprises, the fire operation or the isolation replacement construction is frequently carried out. At present, when the flammable and explosive container and pipeline are subjected to fire welding repair operation, a safety measure is often adopted to isolate one part which possibly causes fire and explosion risks from the other part by using a blind plate, and the other part is subjected to fire operation. If a thin iron plate is used as a blind plate, the blind plate is in contact with the two flanges, and stray current can flow to the isolated side through the blind plate during electric welding operation, so that the danger of ignition and explosion is caused, and the standard requirements are not met; if the strength of the insulating material is not enough, when the party on fire catches fire, the blind plate is easy to be penetrated, so that the party on fire catches fire and explodes, and the protective effect of the blind plate cannot be achieved; the use of standard blind plates is extremely inconvenient due to the thickness and weight. In order to change the current situation, a fire isolation and protection blind plate which has higher strength, is insulating and is convenient to use is needed on site, so that the labor intensity of operators is reduced, and the safety of petroleum and petrochemical fire construction operation is improved.
