Mechanical Tests Required

Transverse Tension Test—One test shall be made to
represent each lot of finished pipe.
Transverse Guided-Bend Test—One test (two specimens) shall be made to represent each lot of
finished pipe.
Nondestructive Test—Each length of pipe shall be
subjected to a hydrostatic test as defined in or, with the
approval of the purchaser, each length of pipe having a wall
thickness up through 0.165 in. (4.2 mm) shall be subjected to
a nondestructive electric test as defined in.
Hydrostatic Test—Each length of pipe shall be subjected to a hydrostatic test in accordance with Specification
A 999/A 999M, unless specifically exempted under the provision of Pressure shall be held for a sufficient time to
permit the inspector to examine the entire length of the welded
seam.
With the agreement of the manufacturer, the purchaser is permitted to complete the hydrostatic test requirement
with the system pressure test, which may be lower or higher
than the specification test pressure, but in no case shall the test
pressure be lower than the system design pressure. Each length
of pipe furnished without the completed manufacturer’s hydrostatic test shall include with the mandatory marking the letters
NH.
Nondestructive Electric Test—Each length of pipe
shall be subjected to a nondestructive electric test in accordance with Practice E 426.
For pipe up through NPS 4, the eddy-current test
shall be applied to the total pipe area. For pipe larger than NPS
4, the eddy-current test is permitted, at the option of the
producer, to be applied to the weld area only rather than the
total pipe area.

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…
