1, high resistance strength: 304 stainless steel pipe mild tensile ≥520Mpa

2, corrosion resistance: the oxide film on the surface of the pipe fittings makes the stainless steel water pipe fittings have good corrosion resistance.

3, long service life: stainless steel material life can reach 100 years, pipe life is more than 70 years.

4, low flow resistance: stainless steel clamping pipe inner wall is smooth, flow resistance is very low.

5. Good seismic performance: high tensile resistance at the clamping place, so it can effectively reduce the possibility of water leakage caused by water hammer vibration, pipeline resonance and earthquake.

6, high pressure resistance: pipeline hydraulic performance test, can withstand pressure 2.5 mpa (24.5kg force /CM2)

7, environmental protection: stainless steel materials can be recycled, pollution-free, conducive to sustainable development, and stainless steel waste also has considerable economic value.

8. Easy installation: insert the pipe into the pipe fitting and press it in place with a special tool, which is simpler than the traditional welding or wire interface.

9. Suitable embedded installation: the clamping pipe fittings can meet the requirements of embedded installation, and can be installed openly or buried in the wall

10, low comprehensive cost: long service life, no maintenance costs, no leakage hidden danger, not easy to aging, low temperature explosion-proof pipe.

11, wear resistance: stainless steel material can withstand up to 30 meters/second of water erosion.

12, health: stainless steel material is a recognized health material that can be implanted into the human body, put an end to secondary pollution of water, keep the purity of water.

13, good sealing performance, no leakage.
