ASTM A106 is an American material standard that defines the requirements for welded and seamless steel pipes used in high-pressure and high-temperature applications. This material is commonly used in the oil and gas industry, chemical industry, and other industrial sectors.

ASTM A106 material is divided into three types: Type A – cast steel pipe; Type B – welded and cast steel pipe; and Type C – welded and cast steel pipe with relatively low thickness. All types have common features of high tensile strength, high pressure resistance, good ductility, and good heat resistance.

ASTM A106 material is made from carbon steel with a higher carbon content than ASTM A53, so it has better pressure and heat resistance properties. ASTM A106 also has higher accuracy with tightly controlled thickness, diameter, and length.

In summary, ASTM A106 is a steel pipe material with excellent properties for high-pressure and high-temperature applications. This material is suitable for demanding applications such as oil and gas pipelines, chemical industry, and other industrial applications. With high accuracy and good pressure and heat resistance properties, ASTM A106 is one of the most commonly used steel pipe materials in the industry.

Designation: ASTM A 106 – 02

Standard Specification for
Seamless Carbon Steel Pipe for High-Temperature Service1
This standard is issued under the fixed designation A 106; the number immediately following the designation indicates the year of original adoption or, in the case of revision, the year of last revision. A number in parentheses indicates the year of last reapproval. A superscript epsilon (e) indicates an editorial change since the last revision or reapproval.
This standard has been approved for use by agencies of the Department of Defense.

^AThe minimum elogation in 2 in. (50.8 mm) shall be determined by the following equation:

e = 625 000A^0.2 / U ^0.9

where:

e = minimum elongation in 2 in. (50.8 mm), %, rounded to the nearest 0.5 %,

A = cross-sectional area of the tension test specimen, in.2, based on specified outside diameter or nominal specimen width and specified wall thickness rounded to the nearest 0.01 in. 2(if the area thus caluclated is greater than the value 0.75 in.2 shall be used), and

U = specified tensile strength, psi.

X2. MINIMUM WALL THICKNESS

X2.1 Table X2.1 lists minimum wall thicknesses for nomi-al pipe wall thickness.

TABLE X2.1 Mimimum Wall Thicknesses on Inspection for Nominal (Average) Pipe Wall Thicknesses

NOTE 1—The following equation, upon which this table is based, may be applied to calculate minimum wall thickness from nominal (average) wall thickness:

t_{n X} 0.875 5 = t_m

where:

t_n = nominal (average) wall thickness, in. and

t_m = minimum wall thickness, in.

The wall thickness is expressed to three decimal places, the fourth decimal place being carried forward or dropped, in accordance with Practice E 29.
NOTE 2—This table covers some wall thicknesses associated with standard pipe sizes but is not meant to imply that these are the only thicknesses obtainable under this specification.

End of pipe end

Plain Ends (PE)

The PE pipes will generally be used for the smaller diameters pipe systems and in combination with Slip On flanges and Socket Weld fittings and flanges.

Threaded Ends (TE)

The TE implementation speaks for itself, this performance will generally used for small diameters pipe systems, and the connections will be made with threaded flanges and threaded fittings.

Beveled Ends (BE)

The BE implementation is applied to all diameters of buttweld flanges or buttweld fittings, and will be directly welded (with a small gap 3-4 mm) to each other or to the pipe. Ends are mostly be beveled to angle 30° (+ 5° / -0°) with a root face of 1.6 mm (± 0.8 mm).

Grooved ends

(example Victaulic pipes): these are pipes that allow a quick connection, used for non-critical applications

Threaded and coupled ends

(T&C), generally used for gas distribution,
Threaded connections are the most common pipe fittings used in oil and gas transportation systems. Due to external vibrations, cyclic loads, and pollution, the fitting parts may start getting loose, which could result in pipeline leaks and other environmental disasters. It is of great significance to develop a reliable technique that could provide…

Coating Pipe ASTM A106
External FBE Coating Pipe (Pipe PP) – Pipe PE Pipe Epoxy (FBE)		Fusion Bonded Epoxy (FBE) coating protects pipe surfaces against corrosion. Double or triple layers of FBE may even increase the resistance to friction and abrasion. FBE coating is also used as the primer layer in 3-layer PE/PP coating systems. Electrostatic epoxy powder is sprayed onto a pipe at a temperature typically around 220 – 235°C. On reaching the hot pipe surface, the epoxy powder melts and forms an uniform layer of epoxy coating on the pipe.




3 Layer PP/PE Coating Pipe (Pipe FBE ) – ( Pipe PE/PP layer		In addition to an anti-corrosion layer of FBE coating, mechanical protection can be added by applying a layer of Polyethylene (PE) or Polypropylene (PP). An adhesive layer takes care of the bonding between the FBE and PE/PP layer. Granules of PE/PP are extruded onto the passing pipe, forming a solid coating layer. Side extrusion is most commonly used, where a sheet of PE/PP is wrapped around a pipe. For smaller diameter pipes, so-called sleeve/ring extrusion is a common process.




External Liquid Coating Pipe (Pipe PU)		With external liquid coating, coating is applied to the outside pipe surface by a spraying system, providing corrosion protection for the pipe surfaces. There are multiple coating types available e.g. liquid epoxy, polyurethane (PU), or e.g. (UV-curable) laquer.


Internal Liquid Lining Pipe polyurethane (PU), or 2-component coating.		Internal liquid lining is a coating layer on an internal pipe surface to protect against corrosion or to optimize flow efficiency. There are multiple coating types available such as liquid epoxy, polyurethane (PU), or 2-component coating. After placing the pipe in the internal liquid coating station, the pipe ends are sealed off and a lance with the spraying gun system is moved through the pipe. Pre-heating could be an option for internal liquid coating.




Internal FBE Lining Pipe Fusion Bonded Epoxy (FBE)		An internal FBE coating is used to protect the inner surfaces of steel pipes from the influence of corrosion and light mechanical impacts and it provides excellent resistance to cathodic disbondment. The internal Fusion Bonded Epoxy (FBE) system is based on an epoxy powder spray system, mounted on a lance. The lance moves through the pipe while the epoxy powder is sprayed onto the internal pipe surface. The pipe must be heated so that the epoxy powder melts onto the pipe. After FBE application, the layer requires curing.





Cement Mortar Lining (CML) Pipe		Cement Mortar Lining (CML) is a method for applying a mixture of sand, cement and water onto internal pipe surfaces using a centrifugal spinning or pooring method. A smooth and compact layer of cement mortar protects water pipes against corrosion and abrasion. A characteristic of CML is that blasting the pipe surfaces is not necessarily required prior to the CML application. Selmers has solutions for factory applied and in-situ applied CML.




Concrete Weight Coating 3LPE/PP-coated Pipe		During the concrete weight coating process, concrete is applied onto the pipe. The concrete layer adds additional weight to pipes to compensate the buoyancy of submarine pipelines, and it also provides protection from external influences. Impingement: 3LPE/PP-coated pipes with weld cage or wire mesh reinforcement. Concrete is sprayed at the pipe by high speed application drums. Compression: FBE or 3LPE/PP coated pipes with concrete wrapped around the pipe along with wire mesh reinforcement.




PU Foam Coating polyurethane foam (PUF) Pipe		To keep substances in a pipeline at the correct temperature, polyurethane foam (PUF) insulation coating is commonly used for hot oil transmission lines as well as in district heating and cooling. Pipe-in-pipe application consists of an inner pipe and an outer jacket; the space between them is filled with PUF. Another manner for applying PUF is spraying PUF onto a rotating pipe, with an optional extra mechanical protection layer.




PP Foam Coating Multi-layer coating with polypropylene (PP) Pipe		Multi-layer coating with polypropylene (PP) foam providing high thermal insulation; this is used for deepwater pipeline projects. In some cases glass synthetic PP (PP enforced with glass fibre spheres) is used instead of PP foam. On top of a 3-layer PP coating, various layers of PP foam ensure a pipe gets the insulating characteristics required. Finally, mechanical protection is added with a solid top layer of PP.
