The Design Of Natural Gas Pipelines

摘要

The modern pipeline design engineer must take into consideration many new factors - for instance, the federal Gas Pipeline Safety Rules, 49CFR Parts 191, 192 and 193. These include requirements such as maximum spacing for mainline shut-off valves, heavier wall thickness in populated areas and some design at 50% of SMYS (specified minimum yield strength). Most states have their own pipeline safety rules which can be more stringent than the federal rules. In addition, there are EPA regulations that are necessary to be complied with such as an environmental impact statement for the entire system, limits on exhaust emissions, right-of-way screening before excavation, etc. Your final design must comply with all such regulations.
