In the past two years, a variety of accidents, once a very serious problem, then everyone will immediately talk about the transfer of attention to the past, and recently, the fire has become a focus, so the state recently for the fire problem, but also very concerned about the fire, especially the layout of the pipeline, the depth of the pipeline groove has a new standard, so the fire pipeline pressure groove is deep enough to leak? What is the classification of fire protection pipes?
What is the classification of fire protection pipes
1、Ductile iron water supply pipe
Ductile iron pipe is made by adding ductile ink agent to 18 or more cast iron, and then cast by centrifugal ductile iron machine at high speed, called "ductile cast iron pipe", also called ductile cast iron pipe, ductile iron pipe and ductile cast steel pipe.
Copper pipe is also called purple copper pipe. A non-ferrous metal pipe, is a pressed and drawn seamless tube. Copper pipe has a strong, corrosion-resistant property and has become a contractor for modern residential commercial housing plumbing, heating and cooling pipe installations.
Alloy pipe (Alloypipe) is a seamless steel pipe, its performance is much higher than the general seamless steel pipe, because this steel pipe contains more Cr, its resistance to high temperature, low temperature, corrosion resistance is unmatched by other seamless steel pipe, so the alloy pipe in the petroleum, aerospace, chemical, electric power, boilers,, military and other industries are more widely used.
Composite pipe (Compositepipe) is a combination of two or more materials from the pipe, is based on metal pipe, inside and outside welded polyethylene, cross-linked polyethylene and other non-metallic materials molding, with the advantages of metal pipe and non-metallic pipe
Plastic pipe as an important part of chemical construction materials, with its superior performance, health, environmental protection, low consumption, etc. is widely accepted by the majority of users, mainly UPVC drainage pipe, UPVC water supply pipe, aluminum-plastic composite pipe, polyethylene (PE) water supply pipe materials
How to do when the fire pipe leaks
Puchi pipe leak detector can effectively find out the leak, Puchi pipe leak detector through the sensor will leak sound signal collection, the collected signal through the host processing, to visualize the spectrum and signal column on the host screen, while the sound will also be output to the headphones through the host, through the "listen", "see" two ways combined. "See" two ways to combine, analysis and judgment of water leakage point. The "census mode" + "positioning mode" double lock water leakage point, can be accurate, fast, effective solution to all kinds of home pipe leakage problem.
In general, the basic detection method is, connect the pipe leak detector host, headphones, sensors. Turn on the switch, put on the headphones, place the pipe leak detector sensor on the road above the pipe line, place it step by step according to the length of the pace, step by step, the closer to the leak, the stronger the signal, the farther away from the leak the weaker the signal, by comparing the signal strength between different points to achieve the purpose of detecting leaks. Therefore, we use the pipeline leak detector, a single point in the leak signal is not meaningful, to repeatedly compare multiple points, compare the sound vibration of the larger place is the leak, of course, we have to consider many other additional factors, such as the direction of the leak breakage mouth, because the pipe is round, if the side of the leak, the larger point may instead be on the side of the road above the pipe, rather than Being above the pipeline road, so the location of the pipeline to know, in addition to the tee, bend, water pressure, burial depth, buried layer, etc. will have an impact on the detection to take these into account.
The above content is mainly a small introduction to the fire pipeline leakage? Fire pipeline is a very important pipeline, the depth of the pipeline arrangement is to meet the standard, after all, the standard is not so easy to get, there are professional measurements, generally speaking, as long as the depth is near the standard, the possibility of leakage is very low, so this is not too worried.
