The usage of pipeline openning the hole with pressure, connecting laterals and plugging:
 
       It is mainly used in pressure pipeline below 7 Mpa of low pressure, normal pressure and middle pressure. Under the situation where the pressure pipeline network transports continously the medium, the production does not stop and pipelines do not empty and sweep, we can open the hole with pressure to any material pressure pipeline and valves, connect and change laterals ( pipelines and valves), add and connect the bypass, change or add valves, replace the pipe, set up the pipeline diversion, treat internal failture of pipeline and connect the pipeline flow with pressure.
 
       This technology is an operation technology that under the close state, by the machine cutting method, we cut the round shape on the operation pipeline and container and realize the pipeline connection, replacement and plugment. This operation not only does not affect the normal production of the closed system, but also ensures to complete the connection work with safety, high-efficient and environmental protection. It realised the operation with pressure under the situation where devices do not stop the production, which improved the efficacy more than 10 times.
    
Technology Features:
1, Advanced technology can work under pressure, which changes the traditional operation such as shutdown, decompression, diffusion and the use of fire in the practice;
2, High economic benefit. It reduces the investiment of the labor and material resource, improves the efficiency and reduces labor intensity and consumption,
3, Safety and non pollution for the environment.
 
Technology application scope:
       widely used in the pipelines that transport the inflammable, explosive, toxic and hazardous liquid and gas such as crude oil, chemicals, liquefied petroleum gas, coal gas and natural gas, and in the urban water and heat supply pipelines who work continously with pressure.
