Can the gasoline pipelines in a chemical plant be laid directly underground?

The two medium pipelines are carbon steel pipes filled with gasoline; they run within the refined oil tank area, from the storage and transportation tanks to the vehicle loading pier, passing through vehicle roads and fire roads. The operating temperature of the pipeline is 30°C, the design temperature is 65°C, the operating pressure is 0.1–0.5 MPaG, the design pressure is 1.0 MPaG, and the external insulation thickness is 50 mm. It will likely take about 20 meters of laying. The questions are as follows: 1. Can these 2 pipelines be buried directly in the ground? What are the relevant standards for implementation? 1. If it cannot be laid directly underground, is it possible to use a trench? What are the precautions?
