Pipe (fluid conveyance)VIDEO ON THE TOPIC: How To Build A Rocket (From Scratch)
It can also be used for structural applications; hollow pipe is far stiffer per unit weight than solid members. In common usage the words pipe and tube are usually interchangeable, but in industry and engineering, the terms are uniquely defined. Depending on the applicable standard to which it is manufactured, pipe is generally specified by a nominal diameter with a constant outside diameter OD and a schedule that defines the thickness.
Tube is most often specified by the OD and wall thickness, but may be specified by any two of OD, inside diameter ID , and wall thickness. Pipe is generally manufactured to one of several international and national industrial standards. Many industrial and government standards exist for the production of pipe and tubing. The term "tube" is also commonly applied to non-cylindrical sections, i. In general, "pipe" is the more common term in most of the world, whereas "tube" is more widely used in the United States.
Both "pipe" and "tube" imply a level of rigidity and permanence, whereas a hose or hosepipe is usually portable and flexible. Pipe assemblies are almost always constructed with the use of fittings such as elbows, tees, and so on, while tube may be formed or bent into custom configurations.
For materials that are inflexible, cannot be formed, or where construction is governed by codes or standards, tube assemblies are also constructed with the use of tube fittings. Additionally, pipe is used for many purposes that do not involve conveying fluid. Handrails , scaffolding and support structures are often constructed from structural pipe , especially in an industrial environment. There are three processes for metallic pipe manufacture.
Centrifugal casting of hot alloyed metal is one of the most prominent process. Seamless SMLS pipe is formed by drawing a solid billet over a piercing rod to create the hollow shell. As the manufacturing process does not include any welding, seamless pipes are perceived to be stronger and more reliable. Historically, seamless pipe was regarded as withstanding pressure better than other types, and was often more available than welded pipe.
Advances since the s in materials, process control, and non-destructive testing, allow correctly specified welded pipe to replace seamless in many applications. The weld flash can be removed from both inner and outer surfaces using a scarfing blade.
The weld zone can also be heat-treated to make the seam less visible. Welded pipe often have tighter dimensional tolerances than the seamless type, and can be cheaper to manufacture. There are a number of processes that may be used to produce ERW pipes. Each of these processes leads to coalescence or merging of steel components into pipes. Electric current is passed through the surfaces that have to be welded together; as the components being welded together resist the electric current, heat is generated which forms the weld.
Pools of molten metal are formed where the two surfaces are connected as a strong electric current is passed through the metal; these pools of molten metal form the weld that binds the two abutted components.
ERW pipes are manufactured from the longitudinal welding of steel. The welding process for ERW pipes is continuous, as opposed to welding of distinct sections at intervals. ERW process uses steel coil as feedstock. In this process, the current to weld the pipe is applied by means of an induction coil around the tube. There are two technologies that can be used to manufacture steel pipes of sizes larger than the steel pipes that can be produced by seamless and ERW processes.
LSAW are made by bending and welding wide steel plates and most commonly used in oil and gas industry applications. Due to their high cost, LSAW pipes are seldom used in lower value non-energy applications such as water pipelines.
SSAW pipes are produced by spiral helicoidal welding of steel coil and have a cost advantage over LSAW pipes, as the process uses coils rather than steel plates. Tubing for flow, either metal or plastic, is generally extruded. Pipe is made out of many types of material including ceramic , glass , fiberglass , many metals , concrete and plastic. In the past, wood and lead Latin plumbum , from which comes the word ' plumbing ' were commonly used. Typically metallic piping is made of steel or iron, such as unfinished, black lacquer steel, carbon steel , stainless steel , galvanized steel , brass , and ductile iron.
Iron based piping is subject to corrosion if used within a highly oxygenated water stream. Copper tubing is popular for domestic water potable plumbing systems; copper may be used where heat transfer is desirable i. Inconel , chrome moly , and titanium steel alloys are used in high temperature and pressure piping in process and power facilities. When specifying alloys for new processes, the known issues of creep and sensitization effect must be taken into account. Lead piping is still found in old domestic and other water distribution systems , but is no longer permitted for new potable water piping installations due to its toxicity.
Many building codes now require that lead piping in residential or institutional installations be replaced with non-toxic piping or that the tubes' interiors be treated with phosphoric acid. According to a senior researcher and lead expert with the Canadian Environmental Law Association , " In the US it's estimated that 6. Plastic tubing is widely used for its light weight, chemical resistance, non-corrosive properties, and ease of making connections.
In many countries, PVC pipes account for most pipe materials used in buried municipal applications for drinking water distribution and wastewater mains. Pipe may be made from concrete or ceramic , usually for low-pressure applications such as gravity flow or drainage.
Pipes for sewage are still predominantly made from concrete or vitrified clay. Reinforced concrete can be used for large-diameter concrete pipes. This pipe material can be used in many types of construction, and is often used in the gravity-flow transport of storm water. Usually such pipe will have a receiving bell or a stepped fitting, with various sealing methods applied at installation.
These tests can be used to prove that the alloy conforms to various specifications e. Maintaining the traceability between the alloy material and associated MTR is an important quality assurance issue.
QA often requires the heat number to be written on the pipe. Precautions must also be taken to prevent the introduction of counterfeit materials. Pipe sizes can be confusing because the terminology may relate to historical dimensions. For example, a half-inch iron pipe does not have any dimension that is a half inch. As technology improved, thinner walls became possible, but the outside diameter stayed the same so it could mate with existing older pipe, increasing the inner diameter beyond half an inch.
The history of copper pipe is similar. The outside diameter was the important dimension for mating with fittings. There are two common methods for designating pipe outside diameter OD. Designating the outside diameter allows pipes of the same size to be fit together no matter what the wall thickness. Since the outside diameter is fixed for a given pipe size, the inside diameter will vary depending on the wall thickness of the pipe.
For example, 2" Schedule 80 pipe has thicker walls and therefore a smaller inside diameter than 2" Schedule 40 pipe. Steel pipe has been produced for about years. The pipe sizes that are in use today in PVC and galvanized were originally designed years ago for steel pipe. The number system, like Sch 40, 80, , were set long ago and seem a little odd. For example, Sch 20 pipe is even thinner than Sch 40, but same OD. And while these pipes are based on old steel pipe sizes, there is other pipe, like cpvc for heated water, that uses pipe sizes, inside and out, based on old copper pipe size standards instead of steel.
Many different standards exist for pipe sizes, and their prevalence varies depending on industry and geographical area. The pipe size designation generally includes two numbers; one that indicates the outside OD or nominal diameter, and the other that indicates the wall thickness. In the early twentieth century, American pipe was sized by inside diameter. This practice was abandoned to improve compatibility with pipe fittings that must usually fit the OD of the pipe, but it has had a lasting impact on modern standards around the world.
Typically the pipe wall thickness is the controlled variable, and the Inside Diameter I. The pipe wall thickness has a variance of approximately Not Japan has its own set of standard pipe sizes, often called JIS pipe.
The Iron pipe size IPS is an older system still used by some manufacturers and legacy drawings and equipment. Copper plumbing tube for residential plumbing follows an entirely different size system in America, often called Copper Tube Size CTS ; see domestic water system. Its nominal size is neither the inside nor outside diameter. This code has the force of law in Canada and the US. Europe and the rest of the world has an equivalent system of codes.
Pressure piping is generally pipe that must carry pressures greater than 10 to 25 atmospheres, although definitions vary. To ensure safe operation of the system, the manufacture, storage, welding, testing, etc. Manufacturing standards for pipes commonly require a test of chemical composition and a series of mechanical strength tests for each heat of pipe.
A heat of pipe is all forged from the same cast ingot, and therefore had the same chemical composition. Mechanical tests may be associated to a lot of pipe, which would be all from the same heat and have been through the same heat treatment processes. The manufacturer performs these tests and reports the composition in a mill traceability report and the mechanical tests in a material test report , both of which are referred to by the acronym MTR.
Material with these associated test reports is called traceable. For critical applications, third party verification of these tests may be required; in this case an independent lab will produce a certified material test report CMTR , and the material will be called certified. Pipe installation is often more expensive than the material and a variety of specialized tools, techniques, and parts have been developed to assist this.
Pipe is usually delivered to a customer or jobsite as either "sticks" or lengths of pipe typically 20 feet 6. Typically, pipe smaller than 2 inches 5. The pipe spools are usually tagged with a bar code and the ends are capped plastic for protection. The pipe or pipe spool is retrieved, staged, rigged, and then lifted into place. On large process jobs the lift is made using cranes and hoist and other material lifts.
They are typically temporarily supported in the steel structure using beam clamps, straps, and small hoists until the pipe supports are attached or otherwise secured.
