Something to Support Pipe or Fabrication

Before we reach to the welding, weld, welding machine or welding job also with welding supply, now we read about something to Support Pipe or Fabrication, because at the fabrics I have to steal a little bit time to do this post for Piping & Fabrication.

Underbead Crack.
weld crack

A crack in the heat-affected zone or in previously deposited weld metal paralleling the underside contour of the deposited weld bead and usually not extending to the surface.

Undercut.
A groove melted into the base material adjacent to the toe or root of a weld and left unfilled by weld material.

Van Stoning.
Hot upsetting of lapping pipe ends to form integral lap flanges, the lap generally being of the same diameter as that of the raised face of standard flanges.

Vapor Pressure.
The pressure exerted by the gaseous form, or vapor, of liquid. When the pressure above a liquid equals its vapor pressure, boiling occurs. If the pressure at any point in the flow of a liquid falls below the vapor pressure or becomes equal to the vapor pressure, the liquid flashes into vapor. This is called cavitation. The vapor thus formed travels with the liquid and collapses where the pressure is greater than vapor pressure. This could cause damage to piping and other components.

Vertical Position.
weld position

With respect to pipe welding, the position in which the axis of the pipe is vertical, with the welding being performed in the horizontal position. The pipe may or may not be rotated.

Viscosity.
In flowing liquids, the internal friction or the internal resistance to relative motion of the fluid particles with respect to one another.

Just keep visiting, because we will keep and continue to post this blog, everything all about Pipe, Piping, Fabrication, Fabrics, Weld, Welding, etc. and thanks!

Inside to The Pipe Elements and Welding Type (SAW)

One more day has passed, and I still stuck in this factory without freedom here. And to release this feeling I just open the internet connection and start to post for Piping & Fabrication, and I have to quick because the time is catching me. Now we go inside to the Pipe Elements and Welding Type (SAW).

Statically Cast Pipe.
Pipe formed by the solidification of molten metal in a sand mold.

Straight Polarity.
straight polarity

The arrangement of direct-current arc welding leads in which the work is the positive pole and the electrode is the negative pole of the welding arc; a synonym for direct-current electrode negative.

Stress Relieving.

Cross the Knowledge of Piping Fabrication

Huh, this mind is stuck on the middle of no where, I can't think clearly, I must be got a headache. But, still I will continue this post for Piping & Fabrication, because there is so much article that I have to post. now we already reach to the letter "S" of General Definitions and now we will cross the knowledge of Piping Fabrication.
Saddle Flange.
saddle flange

Also known as tank flange or boiler flange. A curved flange shaped to fit a boiler, tank, or other vessel and to receive a threaded pipe. A saddle flange is usually riveted or welded to the vessel.

Know More about Rolled Pipe, Root Edge, Root Face, etc.

Show that you are care to your family, and that's what I've done last night. I have to taken care a few problems in my family, start from my daughter and the others, and I feel so free now because the problems step by step will solved, I hope. And now continue with the Pipe and Fabrication, now we will know more about Rolled Pipe, Root Edge, Root Face, etc.

Rolled Pipe.
rolled pipe

Pipe produced from a forged billet which is pierced by a conical mandrel between two diametrically opposed rolls. The pierced shell is subsequently rolled and expanded over mandrels of increasingly large diameter. Where closer dimensional tolerances are desired, the rolled pipe is cold- or hot-drawn through dies and then machined. One variation of this process produces the hollow shell by extrusion of the forged billet over amandrel in a vertical, hydraulic piercing press.

Root Edge.
A root face of zero width.

Root Face.
nomenclature root face

That portion of the groove face adjacent to the root of the joint.

Continue of Piping System Reinforcement Definitions

I really hope that my friend will give me some suggestion for this Piping & Fabrication blog, but while I'm waiting for it, I have to fight by my own. But still with the hope that I have, I believe soon or later I will reach what I want to. and this is the Continue of Piping System Reinforcement Definitions.
Quenching.
quenching

Rapid cooling of a heated metal.

Radiographic Examination or Inspection.
Radiography is a nondestructive test method which makes use of short-wavelength radiations, such as X-rays or gamma rays, to penetrate objects for detecting the presence and nature of macroscopic defects or other structural discontinuities. The shadow image of defects or discontinuities is recorded either on a fluorescent screen or on photographic film.

Reinforcement.
In branch connections, reinforcement is material around a branch opening that serves to strengthen it. The material is either integral in the branch components or added in the form of weld metal, a pad, a saddle, or a sleeve.

Surf The Deepest of Welding Position, Pressure in the Pipe System

Another day we have passed again, but this faith still the same, there is no change at all. Oh God, please give me some miracle so I can continue this life with the new hope and new life. That's what I said inside this heart, but anything happen, I still try to give this Piping & Fabrication continuous post. And today we will Surf the deepest of Welding position, Pressure in the Pipe System.

Plastic.
A material which contains as an essential ingredient an organic substance of high to ultrahigh molecular weight, is solid in its finished state, and at some stage of its manufacture or processing can be shaped by flow. The two general types of plastic are thermoplastic and thermosetting.

Polarity.
Polarity

The direction of flow of current with respect to the welding electrode and workpiece.

Porosity.
Presence of gas pockets or voids in metal.

Positioning Weld.
weld position

A weld made in a joint which has been so placed as to facilitate the making of the weld.

Postheating.
The application of heat to a fabricated or welded section subsequent to a fabrication, welding, or cutting operation. Postheating may be done locally, as by induction heating; or the entire assembly may be postheated in a furnace.

Postweld Heat Treatment.
postweld heat treatment

Any heat treatment subsequent to welding.

Preheating.
The application of heat to a base metal immediately prior to a welding or cutting operation.

Pressure.
pressure

The force per unit that is acting on a real or imaginary surface within a fluid is the pressure or intensity of pressure. It is expressed in pounds per square inch:

pressure

where     p = absolute pressure at a point, psi (kg/cm2)
              w = specific weight, lb/ft3 (kg/m3)
              h = height of fluid column above the point, ft (m)
              pa = atmospheric pressure, psi (kg/cm2)

The gauge pressure at a point is obtained by designating atmospheric pressure as zero:
    where p = gauge pressure.

To obtain absolute pressure from gauge pressure, add the atmospheric pressure to the gauge pressure.

Pressure Head.
From the definition of pressure, the expression p/w is the pressure head. It can be defined as the height of the fluid above a point, and it is normally measured in feet.

Purging.
The displacement during welding, by an inert or neutral gas, of the air inside the piping underneath the weld area in order to avoid oxidation or contamination of the underside of the weld. Gases most commonly used are argon, helium, and nitrogen (the last is principally limited to austenitic stainless steel).
Purging can be done within a complete pipe section or by means of purging fixtures of a small area underneath the pipe weld.

GENERAL DEFINITIONS

Absolute Viscosity
Absolute Viscosity
Absolute viscosity or the coefficient of absolute viscosity is a measure of the internal resistance. In the centimeter, gram, second (cgs) or metric system, the unit of absolute viscosity is the poise (abbreviated P), which is equal to 100 centipoise (cP). The English units used to measure or express viscosity are slugs per foot-second or pound force seconds per square foot. Sometimes,
