    Protection Measures 316L Sanitary Fittings

    316L sanitary pipe fittings have been favored by the water supply equipment industry, single-layer, multi-storey, skyscrapers, factories, warehouses, waiting rooms, waiting rooms are widely used steel. 316L sanitary pipe fittings is a non-burning building materials, it has seismic, bending and other characteristics. In practice, the steel can not only increase the load capacity of buildings, but also to meet the aesthetic needs of architectural design aesthetic, but also to avoid the concrete and other building materials can not bend, stretch defects.

    However, the steel as a building material in the fire, there are some unavoidable defects, its mechanical properties, such as the yield point, tensile and elastic modulus, etc. will be due to the temperature rise sharply. 316L sanitary pipe fittings in the 450 ~ 650 ℃ temperature will lose the carrying capacity, great deformation, resulting in steel columns, steel beam bending, the result of deformation is too large can not continue to use, generally without protection of the steel structure Fire resistance is about 15 minutes. The length of this time also depends on the rate at which the component absorbs heat.

    In order to make the steel structure material overcoming the fireproof insufficiency in the practical application, must carry on the fire prevention processing, its purpose is to enhance the fireproof limit of the steel structure to the design specification stipulation limit scope. To prevent the 316L health-class pipe rapid fire temperature deformation deformation collapse, the measures are varied, the key is to take different methods according to different situations, such as the use of insulation, refractory material block the flame directly burning steel structure, reduce heat transfer Of the temperature to delay the temperature rise of steel, the strength of the weakened time. But no matter what approach, the principle is the same.

    316L sanitary pipe fire protection measures Outer cladding is to add the outer surface of the steel structure can be cast in situ, you can also use spray method. Cast-in-place solid concrete cladding is usually reinforced with steel wire mesh or rebar to limit shrinkage cracks and to ensure the strength of the shell. Spraying method can be applied to the surface of the steel structure in the construction site to smear sand pump to form a protective layer, 316L sanitary pipe fittings can be lime cement or gypsum mortar, can also be mixed with perlite or asbestos.

    316L sanitary pipe fittings welding

    316L sanitary pipe fittings with good welding performance. All standard welding methods can be used for welding. Welding can be based on use, respectively 316Cb, 316L or 309Cb stainless steel filler rod or welding rod. For the best corrosion resistance, the 316 section sanitary pipe welding sections need to be post-weld annealed. If 316L stainless steel is used, no post-weld annealing is required.

    316 stainless steel, its corrosion resistance, atmospheric corrosion resistance and high temperature strength is particularly good, can be used under harsh conditions; with its excellent work hardening. Sanitary valves are widely used in machinery, equipment, chemicals, dyes, paper, oxalic acid, fertilizers and other production equipment; photography, food industry, coastal facilities, rope, CD rods, bolts, nuts.
