Product Benefits:
1. No inherent scrap value thus reducing risk of theft.
2. Moderate weight and easy installation.
3. Can be used in -30℃ to 70 ℃degrees environment.
4. 30 years of service life.
5. Tested by national security agencies. Compressive, bending and
impact resistant. Heat, cold, acid, etc.
6. Corrosion resistance, meet the needs of environmental
protection, and reduce the exploitation of mining resources;
beautify the city, classify the coloring, and enhance the taste of
the city.
Standards and features:
1. high strength. Tensile strength σs≥420MPa, yield strength
σs≥300MPa, same as low carbon steel, three times that of gray iron
2. Good toughness. The impact value is similar to that of medium
carbon steel, which is more than 10 times that of gray iron
material.
3. Good plasticity. The elongation is as large as 7%, which is
similar to high carbon steel, while the gray iron steel has an
elongation of zero.
4. Strong corrosion resistance. In the water spray corrosion test,
the corrosion amount in 90 days is only one tenth of that of the
steel pipe, which is one tenth of that of the gray iron pipe. The
service life is twice that of gray cast iron, which is 5 times that
of ordinary steel pipe.
