1 General Provisions
1.0.1 This code is revised for safety production, environment protection, energy saving, laboring conditions improving, technical advancing and economic in compressed air station design.
1.0.2 This code can be applied to the new-building, reconstruction or expansion of compressed air station and pipe for both piston air compressor and helical-lobe air compressor which operate pressure is less or equals to 1.25MPa (gauge pressure), or centrifugal air compressor which is less or equals to 500m3/min (unit air displacement).
This code cannot be applied to the design for compressed air station and pipe at underground well, cave and any other special locations.
1.0.3 Except E grade for compressed air station with cylinder oil-free lubrication piston air compressor and non-oil spraying helical-lobe air compressor, fire hazard danger class for any other compressed air stations are all D grade.
1.0.4 Former building, equipment and pipe Shall be fully utilized during design of reconstruction and expansion of compressed air station and pipe.
1.0.5 Beside this code, any current national provision on obligatory standard shall be followed in design of compressed air station and pipe.
