Pipe segment diagram for a cold low-pressure separator gas line (冷低分气) featuring a detailed isometric layout. It specifies φ114×6 pipe dimensions using 20# carbon steel material. The drawing includes 44 distinct weld points and incorporates gate valves (Z41H-40) in DN100 and DN80 diameters. Design conditions are noted at 2.10MPa pressure and a temperature of 50°C. Inspection requirements call for 20% RT (Radiographic Testing) according to JB4730-2005 standards. The layout features precise dimensional annotations and component details like an E.R.DN100x50 concentric reducer.
