Problems solved by technology

[0003] Explosion-proof walls are used more and more in offshore platforms. At present, the main form is corrugated plate or reinforced plate explosion-proof walls, which absorb the impact energy of explosions through the plastic deformation of the explosion-proof wall structure. The plastic deformation of traditional explosion-proof walls is large, and the surrounding Inadequacies such as complex structural connection construction and low explosion resistance

Abstract

The invention discloses a corrugated core laser welding sandwich plate blast wall, and belongs to the technical field of explosion proof equipment. The corrugated core laser welding sandwich plate blast wall comprises a corrugated core laser welding sandwich plate, a vertical support structure and a horizontal support structure, wherein the laser welding sandwich plate comprises a corrugated corelayer, an upper panel and a lower panel, the corrugated core layer is arranged between the upper panel and the lower panel, the four edges of the sandwich plate are connected with a truss panel through an inverted-U-shaped support structure, and the thickness of the upper panel of the sandwich plate is slightly less than the thickness of the lower panel. The provided corrugated core laser weldingsandwich plate blast wall adopts the corrugated core layer, the energy absorption efficiency is high, the occupied space is small, the weight is light, and the installation and the construction are simple and convenient.

Description

technical field [0001] The invention relates to the technical field of explosion-proof equipment, in particular to an explosion-proof wall with corrugated sandwich laser-welded sandwich panels. Background technique [0002] Offshore oil and gas production platforms are offshore equipment that integrates the functions of oil and gas exploration, processing, processing, and storage. Due to the limited space of offshore platforms, dense equipment layout, and harsh offshore operating environment conditions, there are often hidden dangers of oil and gas leakage accidents. Fire and explosion accidents often cause disastrous consequences such as casualties, marine environmental pollution, and property losses. As one of the main measures to reduce the consequences of oil and gas explosions, explosion-proof walls have always been valued. By adding explosion-proof on offshore platforms, equipment with potential leakage and high explosion risks can be separated from key protection area...
