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:Luo what effect of ductile cast iron
It should be chromium, chromium is anti graphitization elements in ductile iron if the content for a long time, will hinder the graphitization of cast iron, the iron cementite microstructure (Fe3C) content increased, the chilling tendency of the cast iron increases, will make iron brittle, hard, affect the mechanical properties and processing properties of nodular cast iron.
Q:Which direction should the spigot of the K9 ductile iron pipe be installed?
Ductile weakness: ductile cast iron pipes connected by human factors such as the operation level of responsibility, influence, construction not convenient. The advantages of PE PE PE pipe has good corrosion resistance and its anti inorganic performance than that of the metal pipe is much stronger in the buried without corrosion, construction convenient. Small diameter PE pipe in the price performance ratio is better than that of steel and ductile iron.PE tube have disadvantages: benzene, gasoline, carbon tetrachloride and other organic solvents have certain effect on pe. If the organic solvent is infiltrated into the polyethylene, the swelling will occur, and its physical properties will be decreased. Its pressure resistance and temperature resistance are poor.
Q:Can the sealing ring of ductile iron pipe be reused?
The sealing ring is hard to install and take off. I have been in this line for six years. I haven't seen it removed. The rubber ring itself is not expensive. It is not necessary to reuse it.
Q:What does "K8" mean in ductile iron pipe grades?
1 ductile iron pipe grade K8, on behalf of the ductile iron 8 grades, K refers to the wall thickness coefficient, the higher the grade, the greater the pressure, the lower the level, the less pressure to bear.2 wall thickness calculation formula: e=K (0.5+0.001DN).
Q:What is the relationship between the installation direction of the ductile iron pipe and the direction of flow?
The use of cast iron by adding more than 18 nodularizer, after centrifugal ductile cast iron machine high speed centrifugal cast pipe, called "ductile" (Ductile Cast Iron Pipes), referred to as ball pipe, ductile iron pipe and ductile iron pipe etc.. The utility model is mainly used for conveying water, and is an ideal choice for tap water pipes.
Q:Can centrifugal cast iron pipe be galvanized or coated with asphalt which is good for corrosion prevention?
1, outdoor grounding of anti-corrosion, we must consider the contact resistance, so it is recommended not to use asphalt, and do not use anti-corrosion paint, preferably galvanized anti-corrosion.2, asphalt anti-corrosion paint has good water resistance, moisture resistance, corrosion resistance. Acid and alkali resistance, salt fog resistance, atmospheric exposure and so on. The utility model is suitable for coating internal and external surfaces of various containers and machinery, underground steel structures and underground pipelines for moisture proof, water resistance and corrosion prevention. The utility model is also suitable for repairing water cracks in houses.3, anticorrosive paint is used in the surface of the object, can be used to protect the interior of the object without corrosion of a kind of paint. It is one of the more commonly used than paint anti-corrosion paint in industrial construction, widely used in aviation, shipbuilding, chemical, oil pipelines, steel structures, bridges, oil rigs and other fields, by the vast number of manufacturers favor building.
Q:How many casting methods are there in ductile iron casting? A 60*6 discus can not have sand holes. Its surface is smooth. What process can be used to make it?
This is such a small piece, do not worry about shrinkage, mainly pay attention to sand hole and slag. With Disa wet molding line, a box of more pieces, suitable for mass production, defects will be relatively less. By using other methods (resin sand coated sand, etc.) can also be the main attention, don't type it, then the level of liquidity and relatively ductile iron, gray iron poor, sand and gas can not go up, sand holes or pores will spread in the discus plane.
Q:How much is the manual installation fee of ductile iron pipes from 100 to 150 per metre?
Upstairs said 9 yuan per meter, about the same, if you use the special (ductile iron pipe installation tool) construction greatly saves the labor cost, very fast and convenient, can search, is a special tool for the new, I hope to help you.
Q:The benefits of ductile iron castings
Nodular cast iron has developed rapidly to be second only to grey cast iron and widely used as cast iron material. The so-called "iron instead of steel", mainly refers to ductile iron
Q:What are the requirements for the hydrostatic test of ductile iron pipes?
The pipe work pressure P is less than 0.5MPa, the test pressure is 2P, the pipe work pressure is greater than 0.5MPa, the test pressure is P+0.5. After the water pressure rises to the test pressure, the pressure is fixed for 10 minutes, and the pipe joint and the pipe body are not damaged and leaked.
