Pressure sealing technology does not require fire to seal the leak, which is safe and reliable. The leaking part can be sealed under pressure without any treatment, which ensures simple and fast operation. It is easy to disassemble without damaging the original sealing structure, which is a very practical sealing technology.
Special sealant injection tools for pressure sealing include: manual, pneumatic, hydraulic, mechanical and other special tools for sealant injection, as well as special tools for construction: including various small-sized pneumatic tools, filling tools, tools for puffs, etc. are various special devices and pressure sealing devices, such as band device, professional clamp, various connections and their accessories, which also makes the pressure structure easier, operation more convenient, and the sealing technology more reliable. tall.
Detailed pressure sealing process: Excavation and sealing of the production pit To prevent landslides in the production pit, there must be a certain slope around the pit. Pressure welding for tee plug. When welding, the pipeline oil pressure must be reduced below 2.0MPa, and cooling measures must be taken for water cooling. The hole is sealed, and before opening the hole, pressure testing is carried out in strict accordance with safety regulations.
When sealing under pressure, the principle of "first high pressure, then low pressure, first inside, outside" should be observed, that is, the high pressure end should be sealed first, and then the low pressure end. be sealed. Before pumping oil, make sure that the insulation layer of the power line is not damaged and the pump is properly grounded before starting the pump. In the event of an electric shock, take emergency action immediately. Pipe cutting, when cutting pipes, before turning on the power, make sure that the switch is not damaged and the power line is well connected. It is also necessary to build an oiler, and the pipeline is pumped up, and finally the blockage is safely released.
Pressurized hot plug is mainly designed for conversion projects of pressure bulk and gas transmission pipelines. It eliminates the leakage of flammable and explosive environments, prevents fire and explosion hazards of equipment, and ensures the safety of pipelines.
Main parts for pressure sealing: flanges, hardware, pipe holes, cracks, welding defects, threaded connections, stuffing box leaks, etc. Generally, the leakage medium temperature can be: -195°C--900°C. Medium pressure leakage: vacuum 0-32MPa (320kg/cm2).
