Outline of "TN No-Blow" |
“NO-BLOW” Gas shutting off method for use on low pressure gas has been developed with Tokyo Gas Co.,Ltd. This method allows gas pipe shutting off works (including cutting-off works) to be carry out without releasing gas into the air. |

System including many function |
It is "TS type" gas shutting off device with made from the foundation cloth made of polyurethane resin with which from the "FLAGRON" type gas shutting off device which is the conventional construction method having enabled the improvement in the further safety, security, workability, and environment nature, and a cost cut. By inserting a bag directly under punching, shutting off with high safety is possible. Since the internal pressure of an elastic bag is low compared with a conventional type, there is no fear of exploding, even if a crack should arise, and it decompresses gradually. |

Economical and speedy hot branching |
Hot branching of traditional was done in the cutting off method. The development of transition with the hot branching fittings, tapping directly in case of existing steel pipe can now be easily taken out the same hot branching of polyethylene (PE) pipe. As a result, workability, work efficiency is improved, it will be achieve significant cost down. |

Shutting off pipeline and disposal unitfor heavy gravity gas |
Based on "No-Blow" method for low pressure, we have made it simple and easy as possible intermediate pressure hot branching and shutting off (heavy gravity gas correspondence). It solve challenges such as not being able to vacuum required can not be reduced pressure for gas piece relationships and customers, and supply a wide range of operation. I also leads shorter construction time, improve safety, and to a significant cost reduction. |

Remove the projection of the servive teeno longer needed |
This is the construction method which cuts the surplus pipe which became unnecessary from the place near a former pipe, and closes the branch hole. By reducing the surplus thing, we will reduce the possibility of the irregular damage to the gas pipe by an excavator etc. |
