5.FAQ:
We have organized several common questions for our clients，may help you sincerely：
1.Q: Why would you choose ductile iron pipe rather than other pipe materials?
 A:The reasons are obvious for that not only ductile iron pipe possesses the inherent strength and flexibility of ductile iron, combined with proven corrosion protection systems, but also the cost savings can be achieved from design to installation and commissioning.
 2.Q:Why can you guarantee the inner of pipes can’t be corroded?
 A: High alumina cement mortar lining and sulphate-resistant cement mortar lining. These two special linings are applicable to inner anti-corrosion for sewage pipes, improving resistance to erosion of the sewage components.
