Piping layout: piping layout should avoid the pillars, the main channel through the gas tube wells to the manifold into the ward corridor medical gas systems engineering, corridors branch pipe installation in the ceiling. Each ward within the layer by introducing tube ward straight pipes on the ceiling corridor leads to medical gas piping design into the ward to treat with the first part of a small pipe with aluminum or PVC cover small cap fastened, protect piping and beautiful effect. Pipeline crossing the floor or wall socket should be added medical gas pipes, pipe diameter sleeve diameter than a standard. Non-destructive testing of medical gas pipeline welds shall meet the following requirements: 1, fusion welding seam quality radiographic evaluation criteria should be consistent with existing national standards, "metal fusion welded joints Radiographic" the relevant provisions of GB / T 3323; (2) high-pressure medical gas piping, stainless steel weld pressure of oxygen, nitrous oxide gas pipelines and -29 degrees Celsius below the low temperature piping, shall be 100% of the radiographic testing, the quality may not be less than the second grade, fillet welds should be three; medical gas systems engineering | medical gas (certified) | medical gas pipeline provided by the Medical Engineering Co., Ltd.
