As a pipe material with a long history, cast iron pipes are widely used in many fields due to their strength, durability, corrosion resistance (especially external corrosion) and good pressure bearing capacity. Especially after the maturity of ductile iron technology, its performance has been greatly improved, and it is still the preferred material for many projects.
The following are the main application areas of cast iron pipes and some typical cases: Municipal water supply system: Recommended products: Cast iron pipes, are the most important and widely used areas. Used to transport drinking water and domestic water. Scenario: Urban main water supply network, water distribution branch pipes, water plant outlet pipes, water transmission trunk lines, community water supply, etc. Advantages: Strong pressure bearing capacity, corrosion resistance (protecting water quality), long life (more than 50-100 years), good toughness (ductile iron, earthquake and shock resistance), reliable sealing (rubber ring connection), good hydraulic performance (smooth inner wall cement mortar or epoxy resin lining). Gas transmission system: Recommended products: Ductile iron pipes are commonly used materials for medium and low pressure gas transmission and distribution networks (especially medium pressure networks). Scenario: Urban gas distribution networks, residential gas pipelines. Advantages: High safety (good toughness, not easy to crack), reliable sealing (rubber ring interface, no welding leakage risk), corrosion resistance (reduced leakage risk), and long service life.
