Why are water pipes and pipelines always made of stainless steel
1. Health and Environmental Protection
Stainless steel materials, as environmentally friendly and hygienic materials of the 21st century, have had many successful application records in manufacturing water pipes in developed countries for many years.
Stainless steel pipes can be 100% recycled, while ABS and PPR pipes cannot be 100% recycled.
2. Corrosion-resistant and long service life
It can avoid the problem of yellow stains on water basins and bathtubs caused by pipe corrosion. Cast iron pipes are prone to corrosion and rusting, have a short service life, and pipe corrosion and scaling are likely to cause blockages.
Under the long-term continuous working pressure as stipulated, the cast iron pipes with a lifespan of up to 100 years are prone to corrosion and rusting, resulting in a short service life. The lifespan of PPR is less than one quarter of that of stainless steel.
3. Thermal expansion coefficient, tensile strength
Stainless steel pipes are one fourth the size of other plastic pipes. The excessively high expansion coefficient can cause water leakage in the pipes when the environmental temperature changes.
The tensile strength of stainless steel pipes is ≥ 530, while that of plastic pipes is ≥ 49. The strength of plastic products is only 9.2% of that of stainless steel. Insufficient strength is one of the factors causing water pipes to leak under external force.
4. Attractive appearance and convenient connection
The inner and outer walls of the product are smooth, resulting in low fluid resistance and a soft color. The design is beautiful. Cast iron pipes are prone to rust and are not aesthetically pleasing.
Stainless steel pipes are connected by compression fitting, which is cost-effective, fast, simple to operate, and safe and reliable. ABS pipes are bonded using ABS resin; while cast iron metal pipes are generally connected by thread, which is prone to leakage. Other stainless steel pipes are connected by welding, which is costly and takes a long time to install.
5. No aging, resistant to high temperatures
The stainless steel pipes show no signs of aging, while the plastic pipes deteriorate severely when exposed to light.
The maximum operating temperature of thin-walled stainless steel pipes can reach above 120℃, and the minimum temperature can reach -20℃. The heat distortion temperature of ABS pipe materials is 80℃. Plastic pipe materials are not resistant to high temperatures and will produce toxic gases when burned.
