Centrifugal Ductile iron Pipe in the industry has become the first choice of water supply pipe materials, and is gradually promoted should be used in gas piping system, the reason is that ductile iron pipe has a steel tube strength and the required elongation, but corrosion resistance is more than twice times the steel tube.
Ductile Iron Pipe as a new type of pipe, its good performance in: Good mechanical properties, saving metal, simple construction, integrated engineering cost economy, high reliability, corrosion resistance, safe water supply and gas transmission; used in the field of water supply pipeline, water supply pipe network, pipeline network of oil transmission pipelines and pipeline network, long-life ductile iron is a kind of iron, carbon and silicon alloy, in which the carbon is spherical Free State graphite exists.
In gray iron, flake graphite produces a ' fragmentation ' effect on iron-based mass. Make it brittle. In ductile iron, spherical graphite eliminates this destructive effect and makes it tough. With the essence of iron, the performance of steel.
Ductile Iron pipe with its excellent mechanical properties and external quality, is a conduit for water supply undertakings, its super pressure-bearing capacity, reliable sealing performance, unparalleled anti-corrosion treatment and water quality assurance system, so that the pipeline water is nearly perfect, even in the complex terrain of saline-alkali land, wetlands, high slopes and deserts, and other balanced soil, can also excellent water supply tasks.
