Cast Iron and Ductile Iron tube and fittings PL739

Cast Iron and Ductile Iron tube and fittings can be offered by our comapny to meet different engineering needs.

The difference between ductile iron and gray iron

1. Different chemical composition

Nodular cast iron contains nodular graphite, which can improve its toughness and strength, while reducing brittleness. Gray cast iron contains a lot of carbon, so that its hardness and wear resistance is high, but the toughness is poor.

2. Different organizational structures

The structure of nodular cast iron contains nodular and ferrite, and the distribution of nodular is uniform. While the structure of gray cast iron is mainly ferrite and pearlite, and the distribution of pearlite is uneven.

3. Different performance

Ductile iron has high strength and toughness, and has good corrosion resistance. It is uitable for the manufacture of high load and high pressure parts. The hardness and wear resistance of gray cast iron are high. It is suitable for the manufacture of friction and wear parts.

Application field
Cast iron : because of its low strength and good vibration resistance. It is often used in the production of parts under compressive stress, such as box, base, etc.
Ductile iron : because of its high strength and good toughness. It is often used in the manufacture of parts requiring high strength and toughness, such as crankshaft, connecting rod and so on.

Ductile iron pipes (DN100-2000) and fittings available from China. ISO certificates and testing documentation available.

1. Made of malleable iron material and with zinc plated finish for corrosion.
2. Used for home application or commercial constructions to provide support for conduit hanging systems.
3. Malleable iron construction with zinc plated finish.
4. Furnished with steel bolt having hardened case after treatment.
5. Beveled lip allows hanging from top flange where clearance is limited.
6. May be attached to horizontal flanges of structural members in top beam or bottom beam positions.
Ps: there are also have universal top beam clamps, wide month top beam clamps, c-clamps, side beam clamps, right angle clamps, parallet clamps, edge clamps for your choice.
