作为经济和社会生活的重要能源,燃气以其环保的特质得到广泛应用。燃气输配工程的管道有钢管、铸铁管、聚乙烯管等材料,目前以聚乙烯材为主。为防止出现泄露问题,这就对管道敷设的技术提出比较高的要求。因为篇幅有限,本文结合工程实践,仅对室外燃气管道敷设工程技术进行初步探讨。 As an important energy source for economic and social life, gas is widely used due to its environmental characteristics. Pipeline of gas transmission and distribution projects are steel pipe, cast iron pipe, polyethylene pipe and other materials, the current polyethylene-based. In order to prevent the problem of leakage, this puts forward relatively high requirements on the technology of pipe laying. Because of the limited space, this article combined with engineering practice, only the outdoor gas pipeline laying engineering technology for a preliminary discussion.
