Abstract
The present article reviews different patented devices of heat-fire protection system of pipeline and cable duct of bulkhead having used fibrous and retardant intumescent materials. Their structures and fillers are considered, benefits and drawbacks are defined. The improved design for duct of bulkhead is offered. It is characterized by advanced equipment reliability, technological and fire retardance effectiveness. It is specially noted that breakthrough fire-fighting technology is introduced in the new device. It implies the usage of fire retardant material, providing with thixotropic properties or high viscosity. In proof of the device efficiency the article reviews the experiment conducted on the model of a fire-retardant device.
Highlights
Fire is one of the most uncontrollable and dangerous power
Under the circumstances it is crucial to ensure the duration of fire protection of pipeline and cable duct of bulkhead, in other words the time required to take measures to resist the spread of fire and put it out
The prototype model of the fire retardant device consisted of a steel thin-walled glass with a diameter of 37 mm (Fig. 2) and a length of 60 mm (Fig. 3) with a wall thickness of 0.5 mm
Summary
Fire is one of the most uncontrollable and dangerous power. Being highly significant for human’s life, on the one hand, it tightly bounds to life threatening, on the other hand. Accidents take place because of different reasons They can be child's games with matches, lack of care while welding or working with gas cylinders, safety violation, equipment failure, negligence, natural disasters and others. There are a lot of devices that help to reduce the risk of deaths in the event of a fire [3,4]. These devices proved to be effective [5] in most cases but some buildings require more effective protection. Solving the problem of localization and shutting down the fire both in industrial and civil buildings and structures are highly significant for the mankind
