Description
Technical field
The present invention relates to the technical fields of gas works pipeline, a kind of pressure pipeline more particularly, to gas works and
Its laying method.
Background technique
In modern cities and towns, combustion gas has used the form of unified supply to provide for the resident in city, on the one hand can
Meet the supply of resident's combustion gas, on the other hand can prevent the generation of the perils such as conventional gas tank explosion.
During fuel gas supply, due to needing to enable combustion gas along pipe motion combustion gas application pressure, so
Would generally using pressure pipeline as main transport pipeline, pressure pipeline as its name suggests, refer to pipeline itself bear internal pressure or
The pipeline of external pressure, when in use, usually first segmentation is transported to gas pipeline installation place to pressure pipeline, then by way of welding
Pipeline is transported into the combustion gas that multiple segmentation pressure pipelines connect into long range formula.
Prior art among the above have the following deficiencies: due to pressure pipeline generally use the type of attachment of welding into
Row connection, and intensity of the type of attachment welded in commissure is lower, thus the pressure being easily segmented in use for some time
The case where junction of solenoid breaks, leads to gas leakage, and then cause safety accident.
