| 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… |
