This is a concise installation guide for T-joint ductile iron pipes, covering key steps including socket joint cleaning, rubber ring installation (with differentiated methods for small and large diameters), pipe insertion, joint angle control, gasket inspection, trench backfilling with specified materials, and post-backfilling pressure testing, to ensure proper and leak-proof pipeline installation.

Ductile iron pipes undergo anti-corrosion treatment to extend their service life, ensure water quality safety, adapt to complex environments, and reduce maintenance costs. In response to the anti-corrosion requirements for ductile iron pipes, the following is an overview of some common anti-corrosion methods.
