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.

Grey cast iron is not allowed for pipes , valves and fittings for media having temperatures above 220 °C and for pipelines subject to water hammer, excessive strains and vibrations. Grey cast iron is not allowed for river valves and pipes fitted on the vessel sides and for valves fitted on the collision bulkhead. Valves on fuel tanks subject to water pressure test pipe cast iron grey iron pipe DUCTILE IRON PIPEGray Iron pipe was introduced to the United States as early as 1817, when it was installed in the Philadelphia water system. Today, more than 611 U.S. utilities have had Gray Iron distribution mains in continuous service for more than 100 years. At least 22 utilities have had Gray Iron mains in continuous service for more than 150 years. Ductile Iron Pipe - DIPRADuctile Iron Pipe than when pumping through any substitute pipe routinely specified. When this difference is taken into account, significant savings can result from the use of Ductile Iron Pipe . Engineering Economy Pumping Costs and Equivalent Pipelines One way to realize the savings available with Ductile Iron Pipe is to consider pumping costs.
Ductile-Iron Pipe and Fittings (AWWA Manual M41) This manual provides both technical and general information to aid in the design, specification, procurement, installation, and understanding of ductile iron pipe and fittings. It is intended for use by utilities and municipalities of all sizes, as well as, design engineers and consultants. Ductile Iron Pipe, Ductile Iron Pipe SuppliersDuctile cast iron pipes are defined as pipes made from molten iron of No. 18 or above by adding spheroidizing agent and then passing through a high-speed centrifugal casting of a centrifugal nodular cast iron machine.

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 special and severe conditions of high pressure , water hammer, and excessive external loads. For more than 50 years, it has proved to be virtually trouble and maintenance Engineering Technical Data & Technical for Thickness Iron Pipe Ductile Iron /Gray Iron Weights Conversion Factors Diameters, Circumferences and Areas for Ductile Iron Standard Cement-Lined Pipe Weights for Pipeline Design Weight of Ductile Iron Pipe and Contained Water These weights are based on minimum class (Thickness Class 51 for 3" and 4" and Class 50 for 6" through 54") Ductile Failure of Cast Iron buried Water Mainsof the pipes in the network both major and minor. 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.
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. Cast iron pipe was gradually superseded by ductile iron pipe , which is a direct development, with most existing manufacturing plants transitioning to the new material during the water pressure test pipe cast iron grey iron pipe
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

Kembla HK Ltd - Pipe and Fittings DistributorDuctile iron , also called ductile cast iron , spheroidal graphite iron , or nodular cast iron , is a type of cast iron invented in 1943. While most varieties of cast iron are brittle, ductile iron is much more flexible and elastic, due to its nodular graphite
