seamless 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. Initially, a half inch pipe did have an inner diameter of 0.5 inches (13 mm)—but it also had thick walls. 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. In the 1930s, the pipe was designated by its internal diameter and a 1⁄16-inch (1.6 mm) wall thickness. Consequently, a 1-inch (25 mm) copper pipe had a 11⁄8-inch (28.58 mm) outside diameter. The outside diameter was the important dimension for mating with fittings. The wall thickness on modern copper is usually thinner than 1⁄16 inches (1.6 mm), so the internal diameter is only "nominal" rather than a controlling dimension.[5] Newer pipe technologies sometimes adopted a sizing system as its own. PVC pipe uses the Nominal Pipe Size.

carbon steel Pipe sizes are specified by a number of national and international standards, including API 5L, ANSI/ASME B36.10M and B36.19M in the US, BS 1600 and BS EN 10255 in the United Kingdom and Europe.

There are two common methods for designating pipe outside diameter (OD). The North American method is called NPS ("Nominal Pipe Size") and is based on inches (also frequently referred to as NB ("Nominal Bore")). The European version is called DN ("Diametre Nominal" / "Nominal Diameter") and is based on millimetres. Designating the outside diameter allows pipes of the same size to be fit together no matter what the wall thickness.

For pipe sizes less than NPS 14 inch (DN 350), both methods give a nominal value for the OD that is rounded off and is not the same as the actual OD. For example, NPS 2 inch and DN 50 are the same pipe, but the actual OD is 2.375 inches or 60.33 millimetres. The only way to obtain the actual OD is to look it up in a reference table.

For pipe sizes of NPS 14 inch (DN 350) and greater the NPS size is the actual diameter in inches and the DN size is equal to NPS times 25 (not 25.4) rounded to a convenient multiple of 50. For example, NPS 14 has an OD of 14 inches or 355.60 millimetres, and is equivalent to DN 350.

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 150 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, 160, 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 gold-flow 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.

In North America and the UK, pressure piping is usually specified by Nominal Pipe Size (NPS) and schedule (SCH). Pipe sizes are documented by a number of standards, including API 5L, ANSI/ASME B36.10M (Table 1) in the US, and BS 1600 and BS 1387 in the United Kingdom. Typically the pipe wall thickness is the controlled variable, and the Inside Diameter (I.D.) is allowed to vary. The pipe wall thickness has a variance of approximately 12.5 percent.

In the rest of Europe pressure piping uses the same pipe IDs and wall thicknesses as Nominal Pipe Size, but labels them with a metric Diameter Nominal (DN) instead of the imperial NPS. For NPS larger than 14, the DN is equal to the NPS multiplied by 25. (Not 25.4) This is documented by EN 10255 (formerly DIN 2448 and BS 1387) and ISO 65, and it is often called DIN or ISO pipe.

The Iron pipe size (IPS) is an older system still used by some manufacturers and legacy drawings and equipment. The IPS number is the same as the NPS number, but the schedules were limited to Standard Wall (STD), Extra Strong (XS), and Double Extra Strong (XXS). STD is identical to SCH 40 for NPS 1/8 to NPS 10, inclusive, and indicates .375" wall thickness for NPS 12 and larger. XS is identical to SCH 80 for NPS 1/8 to NPS 8, inclusive, and indicates .500" wall thickness for NPS 8 and larger. Different definitions exist for XXS, however it is never the same as SCH 160. XXS is in fact thicker than SCH 160 for NPS 1/8" to 6" inclusive, whereas SCH 160 is thicker than XXS for NPS 8" and larger.

Another old system is the Ductile Iron carbon steel Pipe Size (DIPS), which generally has larger ODs than IPS.

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. Plastic tubing, such as PVC and CPVC, for plumbing applications also has different sizing standards.

Agricultural applications use PIP sizes, which stands for Plastic Irrigation Pipe. PIP comes in pressure ratings of 22 psi (150 kPa), 50 psi (340 kPa), 80 psi (550 kPa), 100 psi (690 kPa), and 125 psi (860 kPa) and is generally available in diameters of 6", 8", 10", 12", 15", 18", 21", and 24".

When the sharp-nosed plug front part is formed, the roll onset engagement characteristic is improved. At the same time, the dissolution wastage is likely generated in the plug front part as the heat capacity is decreased. However, when thepredetermined high-temperature strength can be ensured in the plug front part, the piercing/rolling can efficiently be performed without the dissolution wastage.

Specifically, in the seamless pipe piercing/rolling apparatus of the present invention, it is preferable that tensile strength of the plug front part be not lower than 50 MPa at 1100° C. The target temperature of 1100° C. is themaximum temperature at which the plug front part can reach in the piecing/rolling. The reason why the strength required at this point is set to 50 MPa or more is that 1.2 to 2.0 times the tensile strength of the plug front part is required compared withthe tensile strength at 1100° C. of 3% Cr-1% Ni steel which is usually used as the plug material.

According to the seamless pipe piercing/rolling plug of the present invention, even if the stainless steel or high alloy steel is pierced/rolled, the minute seam defects in a rice grain form caused by the oxide film on the plug surface can beeliminated, the generation of the inside surface defects caused by the rotary forging effect (Mannesmann fracture effect) during engaging the material to be rolled in the inclined rolls can be prevented without decreasing the piercing efficiency of thematerial to be rolled. Furthermore, according to the seamless pipe piercing/rolling apparatus of the present invention, the plug front part and/or the plug rear part can be replaced without generating the trouble in jointing the split plugs during seamless pipe making process in on-line operation.

Hydroforming does not require the inner surface of a tubular blank to be coated with a lubricating resin. When a steel pipe is immersed in a resin solution so as to form a resin coating on the surface thereof, a resin coating is also formed on the inner surface thereof; however, the inner coating has no effect on hydroforming. In the case of a carbon steel pipe, the inner resin coating will prevent the pipe surface from rusting.

In the so-called Mannesmann tube making process used as the typical method of producing the seamless pipe, a billet heated to a predetermined temperature is fed to a piercer, and a hollow shell is produced by piercing an axial center portion ofthe solid billet. Then, the pierced hollow shell is passed through an elongating mill (mandrel mill) composed of five to eight stands to undergo a process of reducing the wall thickness of the hollow shell. After or without re-heating the hollow shell,correcting in the form and sizing are performed by a stretch reducing mill or a sizing mill. Then, a finishing process is performed to the hollow shell to obtain the seamless pipe which is of a product.

Therefore, the life-time of plug has a large influence on production cost of the seamless pipe. Particularly, with deep drilling of an oil well or development of oil well in the sea bottom in recent years, an expense ratio of the plug tool costrises more and more in the production cost of the seamless pipe by increasing needs for stainless steel or high alloy steel in which the impact on the plug is increased in the piercing.

However, when the plugs proposed in Japanese Patent Application Publication Nos. 2002-113507, 6-328105, and 2-63604 are adopted, unit cost of the plug becomes expensive compared with the Cr--Ni low alloy steel as describe later, and the expenseratio of the plug tool cost is further increased in the production cost of the seamless pipe.

Power is supplied to a heating coil 60 via a heating unit 62. Then as shown in FIG. 11, the steel pipe 51 is pushed through a pair of guide rollers 58 and 59 disposed right and left sides of the pipe by the pusher 54 in the direction of an axis of the steel pipe, is transferred toward heating coil 60 and is passed through the coil 60. In this way, the pushed steel pipe 51 is successively heated with induced current from the heating coil 60. Since the coil has a circular shape, the periphery of the steel pipe 51 is heated circularly around the axis of the pipe. As shown in FIG. 12, since the front side of the heated portion of the pipe is cooled successively by water 62 spouted from a plurality of holes h formed circularly on a circular channel 60a of the coil 60 so as to obtain cooled circular portion c of the steel pipe 51, only portion t having a width W, of the steel pipe 51, virtually remains in a heated state. The locally heated potion t successively transfers toward the rear end of the pipe as the steel pipe 51 transfers forward. The temperature of the locally heated portion t is kept over a crystallization temperature of the pipe. In the case of a carbon steel pipe, for example, the heated zone having width W in the direction of the steel pipe axis is kept between 760° C. to 900° C. The front end of the steel pipe 51 is transferred forward by a successive pushing force from the pusher 54, but since it is fixed by the arm clamp 57 attached to the pivotal arm 56, the steel pipe is forced to bend successively at the locally heated portion t.

Starting animate abstracts whose actinic agreement is apparent in Table 12 were anniversary acrimonious to temperatures accustomed in Table 13 by application an consecration heating coil, and, by application three-roll anatomy rolling mills, they were formed beneath altitude apparent in Table 13 to accommodate artefact pipes. The amount of stands was assorted depending on the blazon of the pipe; i.e., 24 stands were acclimated for seamless pipe, whereas 16 stands were used for solid phase pressure welded pipes and seam welded pipes.In Table 13, a solid accompaniment burden anchored animate aqueduct was acquired by pre-heating a 2.3 mm blubbery hot formed collapsed band to 600° C., continuously basic the consistent collapsed band into an accessible aqueduct by application a advantage of rolls, pre-heating the both bend portions of the accessible aqueduct to 1,000° C. by agency of consecration heating, added heating the both bend portions by consecration boiler to a temperature of 1,450° C., i.e., to a temperature beneath the melting, at which the both ends were butted by application a clasp roll, and accustomed out solid appearance burden welding. Thus was acquired the animate pipes accepting the agreed alien diameter. On the added hand, seamless animate pipes were produced by heating a continuously casting billet, and bearing accordingly the seamless pipe110.0 mm in bore and 4.5 mm in array by application a Mannesmann arbor blazon mill.

When the bolt is woven, carbon and graphite fibers are decidedly preferred. When the bolt is knit, bottle and ambrosial aramide fibers are decidedly preferred.carbon steel pipecan be formed artlessly by the action of this apparatus as illustrated in FIGS. 1 and 2. The ends of an originally seamless polymeric fluorocarbon tube of adapted admeasurement are durably plugged, with an air basin in one plug, and thetube captivated with a blur of any melt-fabricable fluoropolymer called as an adhesive. Tubular bottle bolt is pulled over the tube and smoothed. The resultant accumulation can be acrimonious in any adapted manner, but finer is amid in a hollowheat-conductive (usually metallic) butt and an air accumulation absorbed to the air inlet. Air pressure, i.e., 1/2-10 psig, is activated and the accumulation placed in an oven, acrimonious aloft the abatement temperature of the adhesive, and maintained at thistemperature for 5-30 minutes. The accumulation is removed from the oven and anon cooled while still beneath burden with a accomplished baptize spray. A abundant beck of baptize should finer not be acclimated back it can could cause warpage unless analogously applied. Natural covection cooling is not adopted back it extends the time at top temperature and causes boundless assimilation of the copolymer into the bottle fabric. After the accumulation cools, the air burden is angry off and the end plugs removed.
