Ductile iron pipe length is generally much
6 meters, the bassoon is also 8 meters!
The spheroidal graphite tube of hot film casting process is generally a single branch with a length of 8 meters. The ductile iron pipes produced by this process are usually large caliber pipes. For example, DN1000 or more.
The water-cooled metal ductile iron pipe has a single length of 6 meters, and the current mainstream ductile tubes are water-cooled metal ductile iron pipes.
