What is the typical net spacing for long-distance pipelines? For installations in the past, a clear spacing of 50 was used. Should the burial depth for long-distance pipelines be greater? Thank you
What is an appropriate clear distance between long-distance buried pipelines and other pipelines?

Refer to GB/T 34275-2017 5.4.2.12: Parallel laying shall meet the following requirements
This distance conflicts with the distance specified in 4.1.9 of GB50253-2014. How should this be handled?
There is no conflict; the distance specified in 4.1.9 of GB50253-2014 assumes construction at the same time, while the distance specified in 5.4.2.12 of GB/T 34275-2017 assumes construction in the same trench. Additionally, according to the explanation in 4.1.9 of GB50253-2014, this distance should not be less than 0.5 m, mainly to ensure proper welding conditions. For safety reasons, it is better to follow the requirements specified in 5.4.2.12 of GB/T 34275-2017
