Product Introduction

More than 300,000 tons of ductile iron grooved pipe fittings, malleable cast iron threaded pipe fittings, malleable cast iron plastic lining pipe fittings, various line fittings and mechanical fittings. Ductile iron is an alloy of iron, carbon and silicon, in which carbon is present as spherical free graphite. In gray cast iron, flake graphite has a "split" effect on the iron matrix, making it brittle. In ductile iron, spheroidal graphite eliminates this destructive effect and makes it tough. Ductile iron has the essence of iron and the performance of steel.

The ductile pipe fittings and manhole covers are characterized by high strength, good toughness, high pressure resistance and corrosion resistance. It has the essence of iron, the performance of steel and long service life. Widely used in tap water, municipal, gas, post and telecommunications, power supply, gardens and other units.
