Cost of pressure welding for gas pipelines

2019-11-27View Original

Thread Content

With the ongoing improvement in natural gas pipeline construction, gas-operated procedures are increasingly used for connections with existing pipelines, especially in high-pressure natural gas projects. I’m working on a project to relocate high-pressure city gas lines, and work needs to be carried out while the gas is still in use. Now the client wants to know the cost of carrying out such work with the gas still present. The project’s pipe diameter is DN500, with a design pressure of 4.0 MPa; what is the approximate cost for one such unit?
