(l) Pipelines shall not pass through buildings that are not related to them ； (2) Piping should be installed overhead or along the ground ； (3) When conduit laying is necessary, measures must be taken to prevent the accumulation of gases or liquids within the conduit, and sealing barriers should be installed at the inlet and outlet devices as well as in the plant building ； (4) The wastewater in the trench should be sealed with a water seal and discharged into the production wastewater pipeline ； (5) Sampling pipes should not be led into the laboratory ； (6) Metal pipes should be connected by welding, unless flange connection is required for special purposes.

The design principles for pipelines carrying flammable liquids, flammable gases, and liquefied hydrocarbons are as follows: 1. Pipelines shall not pass through buildings that are not related to them； 2. Pipelines should be installed overhead or laid along the ground. 3. When trench installation is necessary, measures must be taken to prevent gases or liquids from accumulating in the trench, and sealing barriers should be installed at the inlet and outlet devices as well as at the factory building ； 4. The wastewater in the trench should be sealed with a water seal and discharged into the production wastewater pipeline ； 5. Sampling pipes should not be led into the laboratory ； 6. Metal pipes should be connected by welding, unless flange connection is required for special purposes.
