DN600 LSAW Pipe

how to ensure safety by LSAW pipes?

In the scene of municipal pipe gallery and thermal trunk line above DN600, LSAW pipe can not only meet the demand of large diameter, but also ensure the safety of key nodes, and become the "optimal scheme" of municipal engineering. Huayang has left a large number of application examples of LSAW pipes in municipal projects in Handan and Shijiazhuang.

In the Handan municipal utility tunnel project in 2024, Huayang LSAW pipe was decisively selected for the high-pressure gas transmission section (DN600, pressure 4MPa). The person in charge of the project said: "This pipeline is the core of the whole pipe gallery, and once it leaks, the consequences will be serious. Huayang's LSAW pipe not only passed the water pressure test of 1.5 times the working pressure, but also its post-welding stress relief treatment can avoid weld cracking caused by later settlement. " In the end, this batch of 1200 tons LSAW pipes are used together with the SSAW pipes in the medium-pressure section, which not only ensures the safety of key nodes, but also controls the overall cost. In Shijiazhuang thermal trunk line project, Huayang DN1000 LSAW pipe, with its excellent high-temperature stability, has been running continuously at 120℃ for 12 months without exception, which completely dispels the owner's concerns about the sealing performance of large-diameter pipes.
