— Ductile iron is tough allowing it to endure irregular operating conditions and the demands of handling in the field. — High burst strength makes ductile iron pipe well suited for high-pressure applications. — Ductile iron pipe has proven long term performance and maintenance free operation.

Martensitic Ductile Iron This type of Ductile Iron is produced by quench-and-temper heat treatment, preventing pearlite formation. Martensitic ductile iron possesses very high strength and wear resistance but with lower levels of ductility and toughness. Bainitic Ductile Iron It is a very hard and wear-resistant grade ductile iron material.

Ductile iron pipe, a product of advanced metallurgy, offers unique properties for conveying water under pressure, and other piping uses. It combines the physical strength of mild steel with the long life of gray cast iron. Ductile iron offers the greatest possible margin of safety against service failures due to ground movement and beam stresses.

Vertical Soil Pressures (P e) in Ductile Iron Pipe Design. The vertical soil pressures for ductile iron pipes are essentially calculated in the same manner as for rigid and flexible pipes, with the pipe-soil stiffness factor determining exactly where between the two values is most appropriate.Similar to rigid concrete pipes, either the narrow or wide trench conditions can be critical.

1.1.3 Development of Ductile-Iron Pipe The advent of ductile-iron pipe in 1948 was one of the most significant developments in the pressure pipe industry. Quickly recognized as a pipe material with all the good qual-ities of gray cast-iron pipe plus additional strength and ductility, it was first used for.

Ductile iron pipe provides strength and flexibility as well as proven durability from linings and coatings. This means the lifetime payback on a ductile iron pipeline provides an extremely cost effective solution over other pipeline options. This can be summarised by Any high pressure pipe situation up to PN35 such as pressure water.

Choosing Between Ductile Iron Or Steel Pipes Metal

Choosing Between Ductile Iron Or Steel Pipes Metal

The result here is that Ductile Iron Pipe has a design pressure of 225 psi at 50 yield while steel pipe design uses 150 psi at 50 yield or 225 psi at 75 percent yield. In either case, the result is a calculated wall thickness for steel pipe that is 35 percent thinner than for Ductile Iron Pipe, even though the pipes have the same yield strength.

The ANSI AWWA standard for ductile iron pipe requires factory gauging of the spigot end. Accordingly, pipe selected for field cutting should also be field gauged in the location of the cut and found to be within the tolerances shown in Table 1. In the field, a mechanical joint gland can be used as a gauging device.
