p11 alloy steel pipe

3 125

The biggest advantage of p11 alloy steel pipe is that it can be 100% recycled. It conforms to the national strategy of environmental protection, energy saving and resource conservation. The national policy encourages the expansion of high pressure p11 alloy.
 
p11 alloy steel pipe applications are:  
  p11 alloy steel tube current of p11 alloy steel tube half of total steel consumption accounts for the proportion is only in developed countries, p11 alloy steel pipe use the field to expand to provide a broader space for the development of the industry.According to the research of the p11 alloy steel pipe branch of China Special Steel Association , the demand for high-pressure p11 alloy steel pipe long-term in China will increase by 10-12% annually.
 
 P11 alloy steel pipe size and tolerance
Deviation level Standardized outer diameter tolerance
D1 ±1.5%, minimum ±0.75 mm
D2 ±1.0%. Minimum ±0.50 mm
D3 ±0.75%. Minimum ±0.30 mm
D4 ±0.50%. Minimum ±0.10 mm
