Based on these tests, the maximum recommended direct tap sizes to ensure a water -tight tap are shown below. The old rule of thumb of 3 or 4 threads was based on the much weaker pit-cast pipe . AN EVALUATION OF FAILURE MODES by AMEYA The technology of pipelines saw a vast improvement with the introduction of cast iron pipes in the 1800s. Before that, most small diameter pipes were made of wood. Cast iron pipes gradually replaced the wooden pipes in the 1800s. These cast -iron pipes were cast vertically in pits and later replaced by centrifugally spun cast iron in the 1920s.

Analysis of the failure of a cast iron pipe during its water pressure test pipe cast iron grey iron pipe

A failure analysis has been carried out to determine the causes of the fracture of a cast iron pipe . The failure (see Fig. 1) occurred when the pipeline, already buried, was being subjected to a pressure test .This pipeline is located in the north of Spain, having a length of approximately 200 km and providing water supply to a population of around 500,000 people. Ask the Experts ductile iron, cast iron, and stainless steelDuctile iron is a newer alloy than gray iron . While cast iron has been around as far back as 5th century B.C., ductile iron was first created in 1943. Ductile iron is more elastic than gray iron .

It has been estimated that approximately 25% of the water in the distribution systems is lost due to pipeline leaks. Based on the study we understand that grey cast iron pipes are the one most prone to failure, corresponding to more than 85% of the total failures.

Fatigue Failure of Large-Diameter Cast Iron Mains Water water pressure test pipe cast iron grey iron pipe

These fluctuating stresses are accentuated if the pipe impinges on an object with sharp geometry and high stiffness like a rock or a stone. Fatigue of cast iron has been extensively studied in the context of cast iron bridges, structural elements such as columns, engine blocks, etc, but not in the context of buried, grey cast iron water pipes . GUIDELINES Installation Guide for Ductile Iron PipeDuctile Iron Pipe was produced experimentally in 1948. Minor but significant changes in the chemistry and processing of cast iron result in physical differences at the microstructure level, producing a material with vastly improved fracture toughness and ductility. The resulting Ductile Iron Pipe is substantially more resistant Grey Cast Iron Pipe Fittings AdvantagesCast iron (grey cast iron ) is a historical type of pipe manufactured in the 19th and 20th centuries that is used as pressure pipe for transmission of water and sewage.

How to Tell Ductile Pipe From Cast Iron Pipe Hunker

If the pipe is older than that, then it is cast iron . Cast iron pipes have been around much longer than ductile pipes , which eventually replaced them. Cast iron pipes , in a configuration similar to ductile pipes , have been used actively in North America for at least one hundred fifty years. How to tell ductile pipe from cast iron pipe?How to tell ductile pipe from cast iron pipe?The spheroidal or nodular form of graphite found in ductile iron is accomplished by adding an inoculant, usually magnesium, to the molten iron during the manufacture process. Ductile iron can be identified in a laboratory setting by using a spectrograph to examine its exact composition, or by using a tensile test. Examine the pipe.How to Tell Ductile Pipe From Cast Iron Pipe Hunker Hydrostatic pressure test for ductile iron water pipeline water pressure test pipe cast iron grey iron pipeThe problem that I have is that the maximum working pressure for the system is 25 bar (362 psi) and the rated pressure for the ductile iron pipe that we have is 350psi, the contractor contacted the manufacturer but still they did not answer, and it seems that the manufacturer prefers to go for low factor and maybe they will ask for 350psi water pressure test pipe cast iron grey iron pipe
