The Conduit Ventilation engineering Selection of pipeline route for construction and installation

Pipeline engineering is a project to transport oil products, natural gas and solid slurry. Including pipeline route works, station and depot works and pipeline ancillary works. In a broad sense, pipeline engineering also includes equipment and equipment supply. The basic direction of the pipeline from the starting station to the terminal station shall be determined during the construction of the ventilation project, that is, the plane position of the pipeline shall be determined.

The pipeline between stations of pipeline engineering is an overall closed pressure bearing system, and the transmission pressure is generally 40~70kgf/cm2, and the height can reach 84kgf/cm2. The route of single-phase oil and gas pipelines is usually not limited by the terrain gradient. When selecting the route, the route should be as short as possible, generally not more than 5% of the length of the aviation straight line; Meet the requirements of pipeline transportation process; Select appropriate station site; Large crossing projects should be as few as possible, and the location with small quantities, technical possibility, safety and convenient construction should be selected, which is often an important basis for determining the pipeline route; There are sufficient power, water and building materials supply conditions along the pipeline; Be able to properly handle the relationship between the pipeline and its towns, industrial mines, farmland water conservancy and other buildings (existing and planned) along the line; Avoid unfavorable geological sections, seismic areas and areas with mineral reserves as far as possible; Pay attention to the protection of natural environment; The pipeline route shall be selected at a place with convenient traffic for construction and daily maintenance.
