Seamless steel tube
Smooth steel pipeline according to its production procedure is generally divided into warm rolling, cold attracting 2. According to the product can be divided into normal carbon steel, premium quality steel, normal low alloy steel and alloy architectural steel.
Seamless steel pipeline has an excellent bearing capacity, in the fire water supply system, often as the main pipe or the lower part of the system functioning stress greater parts of the pipeline.
Copper pipeline, stainless pipeline, alloy pipe and steel cord mesh skeleton plastic composite pipeline
This kind of pipe is not easy to corrosion, has excellent hydraulic performance as well as is suitable for fire water system system. Nevertheless, these pipes are relatively high cost as well as less made use of in design technique. Along with pay attention to the steel mesh skeletal system plastic composite pipe can only be hidden usage.
Plastic pipe
China’s fire water supply system using plastic pipe is fairly uncommon, however many industrialized nations allow the use of PVC-C (chlorinated polyvinyl chloride) plastic pipeline in some areas, such pipeline light high quality, easy installation, It has a long life span, yet its mechanical residential or commercial properties as well as fire resistance buildings are poor, and there are clear needs for setup websites and also installment kinds. The brand-new revision of the 2017 version of the self-spray design specification has actually presented this kind of pipe, which can be made use of in some much less dangerous areas.
