Simply put, absolute spread in a rolling mill is the difference in the width of the stock we put in and the width of the finished piece. For instance, if a bar goes in and is rolled to reduce its thickness and it is 4 inches wide when it goes in and is 10 inches wide when it comes out, the absolute spread of the rolling mill in this operation is 6 inches. (The maximum output width, 10 inches, minus the input width, 4 inches, equals the absolute spread, 6 inches.)

As i understand, it should be used in the pipelines where there are minimal or no leakage condition is expected. raise face due to its very shape, ensures a tight coupling with the gaskets. hence gasket is held with the pressure between the two raise faces of the mating flanges.

Economic Order Quantity (EOQ):

in this method, our interest is on the raw material that we are going to use in the production. However, we need to do the EOQ method for each kind of raw material, if the product needs multiple material to be manufactured. Usually, this type of analysis is one shot method, because the period we are planing to order for is long (the assumption is that the period is non-ending).

As for Economic Production Quantity (EPQ):

The concentration is one the final product , which has been manufactured in the plant. This analysis is done once just like EOQ. A company could have more than one product that is when we do this method for each product. Here we assume that the production rate is greater than the demand rate. in this case we will need to manufacture the product for a certain period (production uptime). Then we stop the production (production shutdown) until the next uptime, which should be around the time where the inventory is near finishing. For the case where the demand is greater than the production you just produce the maximum amount you can.

If you mean the powder - you can store it indefinitely in a moisture-free environment. If you meant the mixed concrete - it starts to set in about an hour, so it's mixed 'as an when required'

Tobbing foundry, production foundry, captive foundry, independent foundry...

Stop Boiler Valve (or Crown Valve) is installed on an outlet line of a boiler. It's purpose is isolation of a boiler from a downstream steam line. Its position may be either open or close, it cannot be used for throttling of steam.

Sure, if the cables break, it can fall.

ANSI B18.1.1 is a standard for allowance in the thread of bolts and nuts, in which values of major dia, pitch dia etc is given for different classes of bolts and nuts.

You must monitor your machine from time to time. You could use visual inspection, or some other methods depending on machine. Most popular methods for rotating machinery are vibrodiagnostics, oil anlysis and proactive maintenance,

we use water for maching in WJM, and abrasives in AJM.

Fontargen E206 is an electrode for joining and surfacing of pure copper. DIN 1733: El Cu AWS/ASME/SFA 5.6 : E CU Cu = 97.5%, Ni = 1.5%, Mn = 0.5%, Fe = 0.5% Tensile strength 280 N/mm2 Elongation (l=5d) 34% A sufficent pre heating of the parent metal is a necessary condition for obtaining the given values

In welding technology a Pulsed MIG is a touchless transfer method concerning the electrode and the weld puddle, completed by forming one droplet of metal at the end of the electrode per pulse. Just the right quantity of current is added to drive that one droplet across the arc and into the puddle.

it stands for Variable Frequency Drive. It uses either a local controller or an input signal to control the frequency or speed of a motor.

Priming is a carryover of entrained water with the steam into the engines that affect the turbine blade, break cylinder heads, piston, valves.

Usually, a town or group of towns that are primarily industrial, perhaps based around a major employer such as a steel-works, colliery or aircraft factory, attracting a coterie of allied and supporting trades and businesses.

Actuators are used for the automation of industrial valves and can be found in all kinds of technical process plants: they are used in wastewater treatment plants, power plants and even refineries. This is where they play a major part in automating process control. The valves to be automated vary both in design and dimension. The diameters of the valves range from a few inches to a few metres.

Your best bet is a CO2 laser using an O2 jet. However, I doubt if any but the most determined could hobbyist could build that powerful of a laser. Still, CO2 is your best bet.

If an airplane exceeds it's maximum angle of attack, or drops below a certain velocity aerodynamic STALL is what occurs. It is characterized by separation of the flow over the top surface of the wing. This phenomenon reduces lift which, if designed right, will cause the aircraft to nose dive.

That being said, stall for most airplanes is really only dangerous during take off and landing since there's not much vertical space to recover from the sudden loss of lift.

~3.21, to test take a 100 ml graduated cylinder, fill with 60 mL of water. Set cylinder on balance, tare; then add proppant slowly until water level reaches the 100 mL mark. Adding 40 mL of proppant. Then a simple calculation => g/mL

Green HR has two essential elements: environmentally friendly HR practices and the preservation of knowledge capital. Most people will say that Green HR involves reducing your carbon footprint via less printing of paper, video conferencing and interviews, etc. The most important definition to remember in terms of our current economic situation is the reclaiming of America's top talent. Companies are quick to layoff when times are tough before realizing the future implications of losing that knowledge capital. Green HR initiatives help companies find alternative ways to cut cost without losing their top talent; furloughs, part time work, etc.
