The Design of Gas Engineering for Lucheng city of the third sub-region in Dalian
ABSTRACT
With the wide use of the city gas, which is approved more and more by customers, and the application of gas is taken seriously more and more. The design of gas work is ing the city an important part of the construction on transmission and distribution system. This project is the design of gas engineering for Xin Xing Lu Cheng section in Da lian. According to the general situation, climate condition, the traffic of the Da Lian, to determine the area of gas supply scheme and dispose the layout of work. The gas source of the design is the manufactured gas and the design adopts the low-pressure inlet. The primary contents of this design includes: drawing the general layout of the gas pipeline, a interior of layout plan and system diagram; and select the using equipments of the pipeline cooking stove, water- heater, gas meter, voltage regulation box and other equipments; according to engineering of major equipment and accessories selection, work to the hydraulic calculations of gas work, determine the appropriate diameter, and make the project construction and acceptance requirements.
Keywords: manufactured gas; indoor design; courtyard design; pipe material; hydraulic calculation
