Material issues of sewage, rainwater and circulating water pipelines
Thread Content
What materials do you use for sewage drains, rain drains, and circulating water pipes? Is there any PVC material with steel wire?
I use 20 steel for the circulating water pipeline. When the installation is renovated later, I will know the benefits of using 20 steel. The prerequisite for using 20 steel is that the external anti-corrosion must be done well.
The sewage and rain drains use polypropylene pipes, and the circulating water uses carbon steel pipes.
The sewage and rain drains are made of PVC, and the circulating water is made of Q235-A. This post was last edited by nanjingdaxue on 2009-3-30 13:12 ]
Circulating water generally uses carbon steel. Sewage discharge generally depends on the characteristics of the medium, and most of them use non-metallic materials.
