Abstract The operating requirements for welded steel pipes and fastening connection steel conduits in the relevant codes，standards，collective drawings are introduced. The feasibility and advantages for the fastening connection steel conduits in place of welded steel pipes are analyzed and compared. It is proposed that the designers should select the appropriate line laying protecting tubes based on the laying environment so as to improve the construction efficiency and reduce the costs.

Key words Welded steel pipe Fastening connection steel conduit Laying modes
