3 Scope
3.1 This Atlas is applicable to the design and installation of fire sprinkler systems in constructed, extended and renovated civil and industrial buildings, but not to those in buildings of specific function, e.g. gunpowder, explosive, ammunition, fireworks shop, nuclear plant and plane hangar.
3.2 This Atlas is applicable to the design and installation of water mist suppression systems for the production and storage equipment or loading/unloading facilities in constructed, extended and renovated works, but not to those for transport vehicles and those of the mobile ones.
4 System Type and Applicability
4.1 This Atlas covers wet-pipe, dry-pipe, preaction, deluge, water spray, foam water sprinkler and water mist systems.
4.2 A fire sprinkler system shall be provided in place densely populated, difficult in evacuation, external reinforcement and rescue, and of important nature or high fire risk.
4.3 Fire sprinkler systems are not suitable for places rich in the following articles:
4.3.1 Articles which will explode or burn faster on contact with water;
4.3.2 Articles having strong chemical reaction or producing toxic and hazardous substances on contact with water;
4.3.3 Liquids causing splashing or boiling over on contact with water sprinkling.
4.4 Water mist suppression systems can be used for suppressing fires caused by solids, liquids of a flash point above 60℃ and electric fires as well as for cooling of production and storage equipment or loading/unloading facilities for combustible gases, Classes A, B and C liquids, but cannot be used for suppressing fires where combustion and explosion will be incurred by chemical reaction with water and water mist will cause severe damage to the protected object.
4.5 The contents given in the systems illustrations of this Atlas do not cover fire water source, pressure stabilization system, etc.
4.6 The fire alarm series in this Atlas adopts heat and smoke detectors as usual and other types of detectors may be adopted as required in specific engineering conditions.5 Design and Construction
5.1 The design of fire sprinkler and water mist suppression systems shall comply with the current national standards "Code of Design for Sprinkler Systems" (GB 50084) and "Code of Design for Water Spray Extinguishing Systems" (GB 50219) as well as other relevant codes (specifications).
5.2 All the products incorporated in this Atlas are qualified through testing by the fire departments of the Ministry of Public Security. The design and construction of those not incorporated may refer to this Atlas as well provided they are qualified through testing by the fire departments.
5.3 Distribution piping shall adopt both internally and externally hot galvanized steel pipes. If a steel pipe with the inner wall not anti-corrosive is adopted before alarm valve inlet, a filter shall be provided at the end of such pipe. New models of pipes may also be adopted if approved by fire departments.
5.4 Piping connection shall adopt grooved connections (clamps) or screwed and flanged connections. If a steel pipe with the inner wall not anti-corrosive is adopted before alarm valve, welded connection may be adopted.
5.5 Drainage facilities shall be provided at the position where alarm valve is installed. The drainage pattern shall be specifically designed by designing personnel.
5.6 The arrangement and fixation of piping supports and hangers shall refer to the national building standard design atlas "Supports and Hangers for Indoor Pipelines" (03S402).
5.7 The construction and acceptance of fire sprinkler and water mist suppression systems must strictly comply with "Code for Installation and Commissioning of Sprinkler Systems" (GB 50261) and other relevant codes (specifications); the construction shall be performed according to design drawings and shall be so that the specific requirements of the manufacturer are met.
5.8 Pipes shall be straightened before installation and foreign substances inside the pipes shall be removed; in corrosive environment, pipes and fittings shall be subjected to anti-corrosion treatment according to the design requirements before installation; during installation, any foreign substance inside the pipes shall be removed immediately.
5.9 In case of pipe reduction, a reducer should be adopted; bushing is not allowed at pipeline elbow; if bushing is required, in case of tee joint, only one is allowed while for cross joint, the number shall not exceed 2; for pipelines more than 50mm in nominal diameter, movable joint should not be adopted.
5.10 For installing sprinkler, a specific spanner shall be adopted and the frame of the sprinkler is strictly forbidden to torque; in case of deformed frame or damaged relief element, the sprinkler shall be replaced by another one of the same specification and model.
5.11 As the construction and installation is completed, the system shall be subjected to water pressure test. Where the design working pressure of the system is less than or equal to 1.0 MPa, the pressure for the water pressure test shall be 1.5 times the design working pressure and shall not be less than 1.4MPa; where the design working pressure is greater than 1.0MPa, the water test pressure shall be the design working pressure plus 0.4MPa.The testing point for the water pressure test shall be located at the lowest point of the system piping. For infilling water into piping, empty the air in piping, slowly increase the pressure until the test pressure, hold for 30min, and visually observe the piping which shall be free from leak and deformation and shall has a pressure drop not exceeding 0.05MPa.
5.12 The velocity and flow of the water for piping flushing shall not be less than the design velocity and flow of the system; the flushing should be carried out in zones and segments; for flushing horizontal piping, the drainage pipe shall be so located as to be lower than the distribution branches.
5.13 Hydraulic leak test shall be performed after the water pressure test and flushing is qualified. The test pressure shall be the design working pressure and the piping shall be free from leak after 24h holding.
5.14 Dry-pipe and preaction systems shall additionally be subjected to pneumatic test in which the medium should adopt air or nitrogen and test pressure shall be 0.28 MPA; the system after 24h holding shall has a pressure drop not exceeding 0.01MPa.
5.15 The system, after the construction is completed, shall be subjected to commissioning and then to completion acceptance once commissioning qualified; it shall be put into service provided the acceptance is qualified.
