Product Showcase
 |
Stainless steel can work safely for a long time at a temperature of -270°C - 400°C. No matter if it is under high temperature or low temperature, no harmful substances will be precipitated. The material properties are quite stable. The tensile strength of stainless steel pipe is more than 530N/mm, and it has good extensibility and toughness. |
 |
The inner wall of the stainless steel pipe is smooth and the water resistance is very small, reducing the pressure loss and transportation cost. Due to the low coefficient of thermal expansion, stainless steel effectively reduces heat loss in hot water pipes. Stainless steel is a 100% renewable material that does not cause harm to the environment. |
 |
The thin and dense chromium oxide film enables the stainless steel to have good corrosion resistance in all kinds of water, even if it is buried. The test data shows that the service life of stainless steel water pipes can reach 100 years, hardly requiring maintenance during the life cycle and low cost of use. |
 |
Stainless steel is a healthy material that can be implanted into human body. As far as water supply pipes are concerned, it is the most beneficial to health, and all indicators are in compliance with national standards and requirements for drinking water. It has a smooth inner wall, which does not produce dirt after long-term use, not easily contaminated by bacteria, so there is no need to worry about water quality. |
