The design of gas pipelines and oil pipelines is essentially the same. The same construction processes, welding practices and materials are used for both types of pipelines. The main difference between gas and oil pipelines is the wall thickness and where the shut-off valves are placed. In a gas pipeline, heavier wall pipe is used in areas with higher population density. For oil pipelines, near water crossings, we would use thicker-walled pipe.
