Steps of opening with pressure
Can be in the pipeline medium flow engineering, directly in the pipe welding short flange, install the valve, the hole sealing machine connected to the pipe after opening, and then take the hole machine to take off the valve to complete.
Plugging step with pressure
In order to not stop running on the pipeline flange, valve or a pipeline replacement, two sections must replace flange, valve or pipe in the pipe to put the sealed block (can install temporary diversion pipe) to replace the flange, valve or pipe replacement, after closure and diversion pipe can be cancelled.
Cutting procedure with pressure
The pipeline is flammable and explosive medium, cut into two or more sections. Once a spark will appear safety accidents, using pressure pipe cutting technology with pressure pipe cutting is quite safe with hole plugging in the industry, because the use of cutting tube with pressure extrusion bulging type special tools can solve the security professional. At present, plugging holes do not see how much Qian Shu party industry mainly depends on safety, regular plugging holes, may indicate the occurrence of safety accidents in the construction process of the construction side can bear 100% of the responsibility in the construction contract, to ensure absolute security is to rely on high quality equipment and skilled operation team. Most of the industry is for natural gas, coal gas, liquefied petroleum gas, oil pipeline plugging or cutting, so the main problem is safety, safety must be 100%.
