Ductile iron pipe is sized according to a dimensionless term known as the Pipe Size or Nominal Diameter (known by its French abbreviation, DN). This is roughly equivalent to the pipe's internal diameter in inches or millimeters. However, it is the external diameter of the pipe that is kept constant between changes in wall thickness, in order to maintain compatibility in joints and fittings. Consequently the internal diameter varies, sometimes significantly, from its nominal size. Nominal pipe sizes vary from 3 inches up to 64 inches, in increments of at least 1 inch, in the USA.

Pipe dimensions are standardised to the mutually incompatible AWWA C151 (U.S. Customary Units) in the USA, ISO 2531 / EN 545/598 (metric) in Europe, and AS/NZS 2280 (metric) in Australia and New Zealand. Although both metric, European and Australian are not compatible and pipes of identical nominal diameters have quite different dimensions.

Flanges are flat rings around the end of pipes which mate with an equivalent flange from another pipe, the two being held together by bolts usually passed through holes drilled through the flanges. A deformable gasket, usually elastomeric, placed between raised faces on the mating flanges provides the seal. Flanges are designed to a large number of specifications that differ because of dimensional variations in pipes sizes and pressure requirements, and because of independent standards development. In the U.S. flanges are either threaded or welded onto the pipe. In the European market flanges are usually welded on to the pipe. In the U.S. flanges are available in a standard 125 lb. bolt pattern as well as a 250 lb (and heavier) bolt pattern (steel bolt pattern). Both are usually rated at 250 psi (1,700 kPa). A flanged joint is rigid and can bear both tension and compression as well as a limited degree of shear and bending. It also can be dismantled after assembly. Due to the rigid nature of the joint and the risk of excessive bending moment being imposed, it is advised that flanged pipework is not buried.

Current flange standards used in the water industry are ANSI B16.1 in the USA, EN 1092 in Europe, and AS/NZS 4087 in Australia and New Zealand.

Ductile iron pipe is somewhat resistant to internal corrosion in potable water and less aggressive forms of sewage. However, even where pipe material loss and consequently pipe wall reduction is slow, the deposition of corrosion products on the internal pipe wall can reduce the effective internal diameter. A variety of linings are available to reduce or eliminate corrosion, including cement mortar, polyurethane and polyethylene. Of these, cement mortar lining is by far the most common.

Polyurethane (Plastic wrap) marginally protects piping made of ductile cast iron against corrosion and ensures meeting hygienic standards for drinking water at the same time in the early years. Polyurethane is used for both the inside lining and the outside coating. Because of polyurethane's elasticity, the coating remains intact even if the pipe is deformed. A major problem is that the poly wrap is not able to be uniformly installed or even installed without rips and creates isolated corrosion attacks. Corrosion Experts

Polyurethane coatings were first used in 1972.[citation needed] In comparison with other coatings, the internal polyurethane lining exhibits a high resistance to various different media such as drinking water, wastewater, de-mineralised water, industrial water and gas, as well as to aggressive solutions such as sulphuric acid. The polyurethane outside coating is suitable for all kinds of soil.

Polyurethane is a thermosetting plastic with no solvents, with a three-dimensionally linked molecular structure giving it mechanical stability. The polyurethane used for conating has the following standard properties, according to EN 545 and ISO 2531 standards.

Q: How are ductile iron pipes connected?: There are several methods commonly used to connect ductile iron pipes, including flanged joints, mechanical joints, and push-on joints. Flanged joints involve connecting two sections of pipe by using a flanged coupling. The pipe ends have flanges that are securely bolted together, creating a connection that is both strong and leak-proof. This method is often used for pipes with larger diameters or in situations where a rigid joint is necessary. Mechanical joints use a mechanical joint gland and rubber gasket to create a seal that is watertight. The ends of the pipes are inserted into the gland, and then bolts are tightened to compress the gasket, ensuring a reliable connection. This method is frequently employed in water distribution systems because it is flexible and easy to install. Push-on joints utilize a rubber gasket to create a tight seal between sections of pipe. The gasket is placed in a groove on one end of a pipe, and then the other pipe is pushed onto it, resulting in a compression seal. This method is quick and straightforward, making it suitable for a variety of applications, such as sewer systems and underground piping. Ultimately, the choice of connection method for ductile iron pipes depends on factors such as pipe diameter, application requirements, and installation conditions. It is of utmost importance to adhere to the manufacturer's recommendations and industry standards to ensure proper installation and dependable performance.
