This research is to evaluate the safety of natural gas pipeline with diameter size, education, 500 mm size, education, 800 mm size, education, 1000 mm. Size, education and 1200 mm size, education 1500 mm by dig put at a depth of 1.5 meters in the event by earthquakes in evaluation will consider effects of stress from the force arising from use. And the force from the earthquake by the impact towards natural gas pipeline can be separated into the case as follows: (1).(2) affected by the buoyancy of groundwater (3) effect due to movement of normal fault (4) affected due to movement of the seismic waves in severity. Medium and high, the study found that 600 pipe size mmAnd the 800 mm was stress exceeds the acceptable values. In case the impact due to movement of normal fault sections of pipe size, 1 000 mm.The stress exceeds the acceptable values in the settlement of the soil. Buoyancy of groundwater and the movement of normal faults and pipe size, and 1 200 1 500 mm, mm.The stress exceeds the acceptable values in all cases. By considering the stress under the standard ALA-ASCE 2005, so in the design of gas pipelines should be การคำนึงถึง affected by earthquake In order to increase the safety.Or an explosion of gas pipelines.
