·Convenient and fast construction
Avoid on-site welding operations and threading operations. On-site welding or threading of pipe fittings is laborious, has a high water leakage rate, pollutes the environment, and is likely to cause risks. On-site installation of press-fit pipe fittings is extremely convenient. The installation time is only 13% of welded pipe fittings or threaded pipe fittings, which shortens the construction period, reduces costs, avoids water leakage and reduces risks.
·Corrosion resistance and long service life
The service life of the double compression thin-walled stainless steel water supply pipe is almost the same as that of the current buildings. Its durability and anti-corrosion performance is mainly that the chromium element of stainless steel will form a chromium oxide protective film on the surface in an oxygen environment, even if it is mechanically damaged. It can also regenerate quickly.
·Reliable and safe connection
The compression fittings have high connection strength and anti-vibration. The connection parts are snapped in place at one time to avoid the possibility of loose joints, such as house vibration, water hammer vibration, pipeline resonance, and loosening caused by earthquakes.
·Suitable for embedded installation
The compression pipe fittings meet the requirements of embedded installation, greatly reduce the possibility of water pipe leakage in hidden environments, reduce the risk of maintenance and renewal, and meet CECS153:2003 "Technical Regulations for Building Water Supply Thin-walled Stainless Steel Piping Engineering" (Threaded pipe fittings cannot be embedded installation). The pipe fittings are compact and will not cause fundamental damage to the building.
·Maintenance-free, update-free, superior economic performance
During the service life of the building, there is almost no need to update and maintain the pipe fittings, which greatly saves the cost of environmental renewal, and customer property losses and service losses tend to be zero.
·Solution treatment process
After the stainless steel pipe fittings are formed and welded, they must undergo a solution treatment at 1050°C (treatment under the protection of a full hydrogen atmosphere). It can eliminate the stress in the production process of pipe fittings, reduce the possibility of stress corrosion during use, restore the intercrystalline changes in the production process of pipe fittings, prevent intergranular corrosion during use, eliminate the sensitization phenomenon in pipe fittings welding, and improve the welding seam Corrosion resistance can eliminate the modification phenomenon in the process of pipe fittings, restore the corrosion performance of the material, and restore the brightness of the stainless steel surface (this gloss is different from the polished gloss).
·Surface passivation process
What stainless steel can prevent corrosion is the thin and dense passivation film on its surface, referred to as chromium-rich oxide film. Passivation treatment can restore the chromium-rich oxide film destroyed during processing to its original shape, thereby meeting the requirements of corrosion resistance.
Austenitic stainless steel SUS304 is generally used for fresh water, and the corrosion resistance requirements are relatively high (the seawater or chloride ion concentration is high). Some places recommend the use of austenitic stainless steel SUS316 or SUS316L.
·Health and Safety
Thin-walled stainless steel pipes do not contain environmental pollutants (lead-free, no PVC, no environmental hormones, etc.). Thin-walled stainless steel will not cause secondary pollution to water quality and meet drinking water quality standards. Among the water pipe materials we have seen, stainless steel is a healthy material that can be implanted into the human body.
·Excellent mechanical and physical properties
The strength of thin-walled stainless steel pipes is very high. The tensile strength of 304 stainless steel is greater than 520Mpa, which is twice that of galvanized pipes, 3-4 times that of copper pipes, and 8-10 times that of PPR pipes. It also has good ductility and Toughness, the pipe is not brittle at low temperature and other metal pipes have almost no such function. This is one of the main reasons why the corrosion resistance of stainless steel pipes exceeds that of ordinary metal pipes.
·Long life cycle and low cost
Thin-walled stainless steel pipes and pipe fittings are installed once in place. They do not need to be replaced during the life cycle of the building. The service life is the same as that of the building. Other pipes cannot achieve such a long service life. The overall cost is much lower than other related and pipe fittings. cost.
·Excellent temperature resistance
Thin-walled stainless steel can work safely for a long time at a temperature of -270℃-400℃. Whether it is high temperature or low temperature, the thin-walled stainless steel material will not precipitate harmful substances, and the material performance is stable.
The inner wall of the thin-walled stainless steel pipe is smooth, the inner diameter of the pipe fittings is equal to the inner diameter of the water pipe, the friction resistance is small, the long-term use does not accumulate, and the transportation operation cost is saved.
