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 USA. 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 is usually delivered to a customer or jobsite as either "sticks" or lengths of pipe typically 20 feet, called single random length or they are prefabricated with elbows, tees and valves into a prefabricated pipe spool [A pipe spool is a piece of pre-assembled pipe and fittings, usually prepared in a shop so that installation on the construction site can be more efficient.

Typically, pipe smaller than 2.

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.

An example of a tool used for installation for a small plumbing pipe threaded ends is the pipe wrench. Small pipe is typically not heavy and can be lifted into place by the installation craft laborer. However, during a plant outage or shutdown, the small small bore pipe may also be pre-fabricated to expedite installation during the outage.

After the pipe is installed it will be tested for leaks.

Before testing it may need to be cleaned by blowing air or steam or flushing with a liquid. Pipe supports Pipes are usually either supported from below or hung from above but may also be supported from the side , using devices called pipe supports. Supports may be as simple as a pipe "shoe" which is akin to a half of an I-beam welded to the bottom of the pipe; they may be "hung" using a clevis , or with trapeze type of devices called pipe hangers.

Pipe supports of any kind may incorporate springs, snubbers, dampers, or combinations of these devices to compensate for thermal expansion , or to provide vibration isolation, shock control, or reduced vibration excitation of the pipe due to earthquake motion.

Some dampers are simply fluid dashpots, but other dampers may be active hydraulic devices that have sophisticated systems that act to dampen peak displacements due to externally imposed vibrations or mechanical shocks.

The undesired motions may be process derived such as in a fluidized bed reactor or from a natural phenomenon such as an earthquake design basis event or DBE. Pipe hanger assembles are usually attached with pipe clamps. Possible exposure to high temperatures and heavy loads should be included when specifying which clamps are needed.

The most common process pipe joint is the butt weld. The ends of pipe to be welded must have a certain weld preparation called an End Weld Prep EWP which is typically at an angle of Copper pipes are typically joined by soldering , brazing , compression fittings , flaring , or crimping. Plastic pipes may be joined by solvent welding, heat fusion , or elastomeric sealing.

If frequent disconnection will be required, gasketed pipe flanges or union fittings provide better reliability than threads. Some thin-walled pipes of ductile material, such as the smaller copper or flexible plastic water pipes found in homes for ice makers and humidifiers, for example, may be joined with compression fittings.

Underground pipe typically uses a "push-on" gasket style of pipe that compresses a gasket into a space formed between the two adjoining pieces. Push-on joints are available on most types of pipe. A pipe joint lubricant must be used in the assembly of the pipe.

Large above ground pipe typically uses a flanged joint, which is generally available in ductile iron pipe and some others. It is a gasket style where the flanges of the adjoining pipes are bolted together, compressing the gasket into a space between the pipe.

Developed in the s, these mechanical grooved couplings can operate up to 1,psi working pressures and available in materials to match the pipe grade.

When pipes join in chambers where other components are needed for the management of the network valves, gauges Fittings and valves Fittings are also used to split or join a number of pipes together, and for other purposes.

Valves control fluid flow and regulate pressure. The piping and plumbing fittings and valves articles discuss them further. Cleaning Main article: Tube cleaning The inside of pipes can be cleaned with a tube cleaning process , if they are contaminated with debris or fouling. This depends on the process that the pipe will be used for and the cleanliness needed for the process.

In some cases the pipes are cleaned using a displacement device formally known as a Pipeline Inspection Gauge or "pig"; alternately the pipes or tubes may be chemically flushed using specialized solutions that are pumped through.

In some cases, where care has been taken in the manufacture, storage, and installation of pipe and tubing, the lines are blown clean with compressed air or nitrogen. Other uses Pipe is widely used in the fabrication of handrails, guardrails, and railings. See also Commons has media related to Pipe. 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. The only way to obtain the actual OD is to look it up in a reference table. 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.
