Gas pipeline installation of some of the uses of new technologies

In the era of widespread use of gas for cooking , cast iron pipe is the most popular underground pipeline gas pipe . It consists of gray cast iron , corrosion resistance and long service life . But in the production process , the metal consumed in large quantities , the density is also large, in the construction of the installation is very inconvenient to haul , coupled with its crisp, easy to break, soon to be replaced by welded steel pipe. But there are welded steel pipe joints , whether or spiral steel welded pipe , steel quality and the quality of welds require good control . Seamless Steel is known for its high strength, good toughness, impact resistance, and good VGA CABLE  tight occupy the market has many advantages . But two years ago , polyethylene pipe in the domestic market began to spread , in addition to its more than metal pipes with strong corrosion resistance than the smaller density , ease of handling and installation , but also the main reason for its current market occupied .
  2.PE valves instead of steel valves
 We open the gas valve well , often see some of the well water valve . Even valve well be repainted both inside and outside , then add impermeable agents , it is difficult to prevent moisture moisture continues to rust on steel valves . Over time, the valve switches are very laborious and sealing effect will be weakened. If you are using PE valve , the valve shaft greatly reduce corrosion . In some coastal cities , PE valve well have been put into use, but not yet universal .
    If the use of PE pipe is buried gas pipes a significant advance , there will be realized PE valve PE of all underground pipes , no longer have to worry about stray currents and soil gas flow in the pipeline caused by pipeline water hammer erosion.
  . Trenchless technology start 3
 Trenchless Technology has more than 100 years of history, but in our country it is only in its infancy. Application of trenchless technology, can effectively reduce the manual labor intensity , difficult excavation of some of the lots also have a new breakthrough method . In some important sections , both to ensure the timely construction of the gas , and not blocking traffic , laying of overhead pipes are difficult rivers can be used trenchless construction . There are some common interests and residential owners to obstruct construction , strong cable compensation , then, trenchless technology and can be a good solution to this problem.
 4 pipe corrosion epoxy powder coating
    For outdoor overhead pipes , gas pipes within pipes overhead bridge or gate stations , mostly seamless steel pipe, but only in accordance with regulatory requirements brush primer, rust , paint , but less than six months , we find , paint has come off , rusted steel surface has begun to emerge , so we need repainting every six months , so that  Displayport CABLE trouble , and secondly, does not really play a preservative .
 Disposable construction process large multi- epoxy powder coating steel pipe pile corrosion engineering , let us real insight into the beautiful but good effect preservative preservative technology. In the sea, through the strengthening of multi- level spray pipe service life of up to 100 years. So, from the early to the recent asphalt corrosion corrosion tape wrapped around the many anti-corrosion technology , the people most at ease without affecting the epoxy powder coating undoubtedly beautiful , but expensive, so use very little , generally only in the past overhead valve tube wells or steel bridge corrosion of exposed place .
