长输管道安全仪表系统设计

我国长输管道的快速发展，对其安全平稳运行提出了更高的要求，安全仪表系统（SIS）作为长输管道数据采集与监控系统（SCADA）的重要组成部分显得越来越重要。一个技术先进、性能可靠、应用灵活的安全仪表系统，是长输管道SCADA系统设计时考虑的重点。

Design of Safety Instrumented System in Pipeline

With rapid development of pipelines in ours country, the safety and stability is put forward higher request, Safety Instrumented System （SIS）, an important component of pipelines, is becoming more and more important. SIS system of advanced technology, reliable performance, and flexible application is key point that designers have to consider during designing of pipelines SCADA system.
