Know more Fabrication with the Erection Pipe and Extrude Pipe

This has to be the end of general definitions of piping elements from letter "E", and I intend to do this so I can prepare other post in tomorrow morning. so with Piping & Fabrication still running the mission, now we will go with :

Electric Resistance-Welded Pipe. 

Pipe produced in individual lengths or in continuous lengths from coiled skelp and subsequently cut into individual lengths having a longitudinal butt joint in which coalescence is produced by the heat obtained from resistance of the pipe to the flow of electric current in a circuit of which the pipe is a part and by the application of pressure.

End Preparation. 

The contour prepared on the end of a pipe, fitting, or nozzle for welding. The particular preparation is prescribed by the governing code. Refer to Chap. A6 of this handbook.

Engineering Design. 

The detailed design developed from process requirements and conforming to established design criteria, including all necessary drawings and specifications, governing a piping installation.

Equipment Connection. 

An integral part of such equipment as

pressure vessels, heat exchangers, pumps, etc., designed for attachment of pipe or piping components.

Erection. 

Erection

The complete installation of a piping system, including any field assembly, fabrication, testing, and inspection of the system.

Erosion. 

Destruction of materials by the abrasive action of moving fluids, usually accelerated by the presence of solid particles.

Examination. 

The procedures for all visual observation and nondestructive testing.

Expansion Joint. 

A flexible piping component which absorbs thermal and/or terminal movement.

Extruded Nozzles. 

The forming of nozzle (tee) outlets in pipe by pulling hemispherically or conically shaped dies through a circular hole from the inside of the pipe. Although some cold extruding is done, it is generally performed on steel after the area to be shaped has been heated to temperatures between 2000 and 1600 F (1093 and 871 C).

Extruded Pipe. 

Extruded Pipe

Pipe produced from hollow or solid round forgings, usually in a hydraulic extrusion press. In this process the forging is contained in a cylindrical die. Initially a punch at the end of the extrusion plunger pierces the forging. The extrusion plunger then forces the contained billet between the cylindrical die and the punch to form the pipe, the latter acting as a mandrel. One variation of this process utilizes autofrettage (hydraulic expansion) and heat treatment, above the recrystallization temperature of the material, to produce a wrought structure.

Finally with this piping and fabrication handbook we already add a little knowledge of piping system and fabrication and I hope all of this will be useful to all of us. Thanks!!!
