What are the environmental constraints of pressurized openings?

It is believed that the loss of medium caused serious damage to the operator and easy to leave sequelae. In addition, in the construction of the tape gland project, the operator needs to directly contact the leaking medium, and the existing protection measures cannot guarantee the safety of the operator. Therefore, it is necessary to damage the leakage of the medium and prohibit the operation of the tape gland project.
The outflow has nuclear radiation obstructions.
It is believed that at present, there is no suitable protective equipment for the construction of pressurized sealing engineering under the environment of nuclear radiation hazard in China, and there is no report on the successful case of pressurized sealing in the area of nuclear radiation hazard environment and nuclear device. Therefore, in the environment of nuclear radiation hazards, it is forbidden to carry pressure sealing construction.
Site safety and protection methods are not satisfied with the site and location where there are construction rules for pressure sealing works.
Construction personnel in the construction site, may be directly faced with high temperature, high pressure and corrosive leakage medium may cause direct damage, flammable and explosive leakage medium may be directly faced with equipment and personnel damage, toxic leakage medium may be directly faced with personnel health and life damage.
When the seal portion data is thinned, the leak cannot be clearly detected.
The characteristic of the sealing function is to eliminate leakage by applying a good sealing ratio to the sealing part. If the thinning of the sealing portion is not detected, the sealing portion cannot withstand the sealing specific pressure, and there is a risk of crushing the sealing portion and rupture of the pipe.
The pressure seal part has a data fissure_sensitive leak that cannot prevent its expansion.
The occurrence of pipe cracks is composed of different reasons, and the leakage caused by cracks can be eliminated by using pressure sealing. However, because the pressurized seal cannot eliminate the cause of cracking during the attack, the cracking will continue to expand after the elimination of leakage, and it is difficult to find immediately due to the containment of the sealing part. When the cracking expands to reach less than the strength of the pipeline, it will break suddenly. Therefore, after using the overflow method, the pressure seal can be determined.
