Which is good for water polo cast iron pipe steel pipe?
In summary, if the demand is not high, the use of stable environment, pressure and vibration is not a place recommend the use of ductile iron pipe; if is an important facility for high requirements or site conditions, abnormal conditions, vibration and impact may be relatively large, with ordinary seamless steel tube.
Flexible seamless steel pipe is good toughness, good processing, better than ductile iron corrosion resistance, the price is slightly higher;
The advantage of ductile iron pipe is cheap, corrosion resistance, lack of toughness is poor, not easy to process
