Can buried gas pipelines be laid in the same trench as water supply pipelines?
Thread Content
I would like to ask the teachers: 1. Can buried gas pipelines be laid in the same trench as water supply pipelines (with cathodic protection for the buried gas pipelines)? 2. The operating pressure of buried gas pipelines is 1.5 MPa, with a design pressure of 2.5 MPa; the regional classification for these pipelines is level 3. Is a φ426*11, L360 seamless steel tube suitable? 3. Can pipeline anti-corrosion treatment be carried out in the factory in advance? The pipes come with an anti-corrosion coating out of the factory, which reduces the construction time

Pipes leave the factory with an anti-corrosion coating, which reduces the construction time. Answer: In many municipal or chemical engineering projects involving linear installations, due to site constraints, the pipe anti-corrosion treatment is carried out in specialized anti-corrosion factories to ensure the quality of the protective coating on the pipes. If there is local damage at the site, apply patches to those areas.
1. Can buried gas pipelines be laid in the same trench as water supply pipelines (with cathodic protection for the buried gas pipelines)? Answer: Yes, but the burial depth and location are different; the pipe trench is wider and deeper, while buried gas pipes are generally buried at a shallower depth.
