Auto cad DWG drawing file shows the boundary layout and details of pipeline projects. Expansion joints were provided. When building a boundary wall, an expansion joint is a separation designed to relieve stress on building materials caused by movement induced by thermal expansion and contraction. Temperature changes and seasonal changes mostly cause the movement in the boundary walls. Pipeline entry point and pipeline exit point were mentioned here. Thank you for the downloading the cad file and other cad program from our website.
