CPVC fire protection pipeline system
CPVC fire pipes are a revolutionary new product in the Chinese fire pipe industry that replaces steel with plastic. They have been approved in the revisions of GB 50084-2017 "Code for Design of Automatic Sprinkler Fire Extinguishing Systems" and GB50261-2017 "Code for Construction and Acceptance of Automatic Sprinkler Fire Extinguishing Systems" on May 27, 2017. Compared to traditional fire steel pipes, CPVC fire pipes are sourced from environmentally friendly materials and have undergone significant changes in the installation process. They do not require electricity, save labor, and time, and have the following six unique performance advantages.
Excellent fire resistance performance
Extreme oxygen index LO1:60.
When in continuous contact with flames, the surface turns black and forms a char layer.
The carbonization layer reduces the combustion rate and effectively prevents the transfer of heat to the inner wall of the pipeline.
High pressure performance
Under the condition of meeting the service life of 50 years, the pipeline system bears a pressure of 1.2Mpa and meets the high working pressure requirements of automatic sprinkler fire extinguishing systems.
The pressure value at 50 years is determined based on a long-term hydrostatic test lasting 100000 hours.
According to the GB5135.19-2010 standard, the test pressure value is 6.0MPa, which is 5 times the higher working pressure requirement of the system.
The bursting pressure of the specimen is 10.4MPa.
Excellent corrosion resistance performance
CPVC products have strong corrosion resistance to acid, alkali, salt, and hydrocarbon products due to their high krypton content. Experimental results have shown that long-term use of CPVC fire pipes does not result in microbial erosion of MIC. No scaling (scaling seriously affects the hydraulic performance of pipeline systems, eliminating the huge risk of clogging nozzles with scaling debris). No corrosion phenomenon (both inside and outside will not be corroded, eliminating the risk of water leakage and nozzle blockage caused by corrosion).
Excellent hydraulic performance; Excellent seismic performance; Excellent mechanical performance
Through pipeline flattening experiments, impact tests have shown that the carrying pressure and carrying impact force of CPVC fire pipes are not inferior to those of steel pipes.
| Comparison of Characteristics | Galvanized steel pipe | CPVC fire protection pipeline |
| Product standards | national standardGB/T3091 | American standard ASTMF442, performance meets GB/T5135 |
| Construction cycle | Relatively long | 1/2-1/5 of the steel pipe construction period |
| service life | 5-20 years | 50 years, the same lifespan as the building design |
| Post maintenance | Frequent post maintenance and high repair costs | Use maintenance free |
| corrosion resistance | The quality of the galvanized layer is difficult to guarantee, and the metal corrosion is severe | No corrosion issues |
| Scaling situation | After 1 year of use, there is obvious scaling | No scaling |
| hydraulic performance | High hydraulic friction | Good hydraulic performance, more material efficient |
| Fire performance | Rust and detachment can easily cause nozzle blockage, posing serious fire safety hazards | No blockage, smooth water spraying, able to control and extinguish fires in a timely manner, with fire resistance performance meeting the requirements of GBTT513519 |
| Construction quality | The construction process is complex, and the workers have high quality requirements, making it difficult to ensure quality | Simple construction technology, low skill requirements for workers, and good construction quality |
| Construction Safety | The weight of steel pipes is large, the construction labor intensity is high, there are many electric tools, and construction safety accidents occur frequently | The weight of the pipeline is only 1/7 of the steel pipe, and there is no hot work or electric tools on site for construction safety |
| Environment | There are many on-site equipment, high noise, and poor construction environment | The site is clean, with minimal disturbance and no noise |
| environmental performance | The pollution caused by steelmaking is significant, and the state restricts the galvanizing process | Environmentally friendly materials, clean production, and recycling |
| Comprehensive cost | The labor cost is too high, making it difficult to control the cost | Significant manpower savings, reasonable and stable cost ratios |
