Indoor fire gas (Halon) fire extinguishing system piping and equipment installation
1 Scope
    This technology is applicable to the important rooms, collections library, archives and other construction. Indoor use of Halon gas fire extinguishing system piping and equipment installation. Halon fire extinguishing agent is not conductive, non-polluting characteristics, but only in a confined space can be achieved good results.
2 construction preparation
    2.1 Materials and equipment requirements:
    2.1.1 fire service gas (Halon) fire-fighting equipment, steel, pipe, pipe fittings, valves and ancillary products, all kinds of spare parts, etc., should have certificate of origin and product certification. Entered the scene, so check before installation, validation, must conform to relevant norms, standards and fire protection departments ministerial regulations and requirements.
    2.1.2 in accordance with the construction and installation schedule, after checking the amount of material approach, to test its size, type, size, quality, compliance with design drawings.
    2.1.2.1 Carbon seamless steel pipe and galvanized pipe fittings:
    a pipe: seamless steel pipe galvanized carbon or thicker galvanized carbon steel, galvanized inside and outside wall of uniform, no rust, no card inside wall reinforcement, the wall thickness should be consistent with design requirements. Selection of pipe materials, the internal pressure to withstand the design requirements to be met.
    b tube: galvanized inside and outside by forging steel, zinc coating the surface evenly, no corrosion, no side buttons, random wire, side buttons, threaded incomplete, are not allowed to view such phenomena. In particular the flange to inside and outside the zinc, zinc coating integrity, uniform water line, not a fracture, adhesion dirt and so on.
    2.1.2.2 non-ferrous metal pipes and fittings: The Road and the seamless copper tube, pipe wall thickness inside and outside the uniform, glossy surface inside and outside tube skin smooth, not a threaded pipe failure, angle allowed, partial deduction, random wire phenomenon.
    2.1.2.3 valve: valve after arrival, to do sampling experiment, there should be no cracks, casting good looks, both inside and outside the rules, flexible and close switches, hand wheel without damage.
    2.1.2.4 Equipment: Halon gas cylinders, starter boxes and ancillary equipment and spare parts box specifications, model, size, quality must meet the design requirements, spare parts for its equipment should be complete, the surface of neat appearance, no damage. Carrying, wearing cap, can not be inverted, impact, careful operation is not allowed on direct sunlight and high temperatures, near
