to make it insulated and rust free Gi spray is used.

Fiberglass is easy to install and can be purchased in insulation sleeves. The insulation is comprised of inorganic fibers, which are bonded with special resin. An aluminum-foil facing or vapor retarder is attached. The insulation is usually available in 3-foot sections.

1. safety first, as life is more important then any thing else..!

2. use specialized safety equipment and specialized PPE.

2. designate competent team of persons for the job.

3. take all precautionary measure in case of an emergency.

4. take out all the oil through the drain valve, if no drain valve use fuel/oil transfer pump.

5. put soaking material in the tank for e.g. marble powder.

6. take out all the soaking material with the help of hand tools like brass excavator.

7. pour fresh water for at least 24 hours in the tank.

8. drain the water, clean the tank with any detergent, dry the tank.

and tank is clean and ready to use again.

Low tox drilling mud is water based.

We often find a saw used to cut bolts. Rivets might be cut if we can get the saw on the body, but we often have to drill them out. A sidewinder grinder will make short work of them if you can get it on the body of the fastener. Certainly a plasma cutter will slice through them, but we have to be careful about damaging material around the fasteners when we cut them that way.

Except for the fracking fluid manufacturers, no one knows what's in that stuff - which is a huge problem because there could be anything in it.

It may be recovered for use in construction additives and there also applications like fertilizer. Reuse plan is very depending on the availability of such carbonate sludge, concentration and the species of other impurities.

The very first telegraphs used flags as a signalling system. Although much faster than horses, they relied on line of sight so the message needed to be received and re-sent numerous times. They were an ingenious system but were labor intensive and useless in fog.

The electric telegraphs allowed far longer distances to be covered without manual intervention. Once the technology was established, a message from one side of the country to the other was received instantly. The final link, from the telegraph office to the recipient relied on physical delivery of a message and it was this element that took the time.

yes. It's only technological university in ghana.

The emitter resistor in a common emitter configuration provides negative feedback to the transistor, reducing both its voltage gain and distortion.

Transmission microscopy and reflection microscopy refer to type of illumination used to view the object of interest in the microscope. Reflected light microscopy, also called episcopic illumination or just epi-illumination, uses top-down lighting to illuminate the specimen and the light is reflected back from the specimen to the viewer. This type of illumination is most often used with opaque specimens like metallurgical samples. Transmitted light microscopy, also called diascopic illumination, uses bottom-up illumination where the light is transmitted through the specimen to the viewer. This type of illumination is most often used with translucent specimens like biological cells.

this would need some more detail , to be specific ,

and dependant on whether temperature, pressure , level or flow types.

..

generally you should consider the impact if the system fails / would it result in a catastrophic situation arising, resulting a dangerous condition .?

are there any fail safe emergency arrangements needed to continue cooling via pumps, or safety valves to control a pressure safely.

is the new system about to be commissioned the right type for the application ?

..

is installation - method the correct one.?

are the sample and return pipelines set up correctly ?

are there any intrinsic - safety requirements?

should a valve stem or piece move during its operation ; will it clear any local objects or strike them resulting in a failure ?

.

is the electrical system designed suitably for the power consumption ?

are there any IP - protection sealing requirements needed ?

.

if the application involves a flow measuring system ;

the isolation -- valves should be commissioned by equalising the pressures across the instrument manifold.

then opening slowly theLP low pressure isolator, and then fully,

and finally opening the HP isolator to commission the instrument .

The wooden boat was invented in 1873 by Sir Edgar of Lincolnshire. He was a humble man with a thirst for knowledge and reinventing himself. He loved to invent things and one day he came across half a Walnut shell floating along a stream and was from then on inspired to create the boat.

Yes, melted plastic can hurt you. The primary danger is from a burn. Melted plastic is hot, and it tends to stick to skin and clothing. It is exceptionally dangerous stuff in that regard.

Pipes that have been welded (or melted) together.

this question is related with oil industry

Humber College used to teach about injection molding and plastics industry. It was a really great program for someone who wants to be in this field. I don't think any other college or university teach about plastics injection molding anymore.

I wish Humber can start teaching about injection molding again in future.

If you refer to surface purity, very. if there is dirt, oil, rust, paint, even ink, the substance will get into the molten puddle, and weaken the weld. It may also effect the arc current enough to get porosity in the weld (bubbles) and then you are screwed. If you refer to base material purity (i.e. carbon content) Then not much unless you try to weld high carbon to low carbon (i.e. mild steel to cast iron) then you will run into all kinds of problems. heating up high carbon enough will melt low carbon. You may also notice arc fluxuation depending on carbon content.

Actually, If the problem is only for processing n jobs on only one machine, the solution to minimize the average flow time is easy by using SPT method (short processing time). The method goes by assigning the jobs with short processing times first .

But the problem becomes more challenging when there are m machines; in this case Johnson algorithm is used which only guarantees the optimality for two machines only .

For more than two machines, integer integer programming modes are used.

Plenum refers to a type of building and how its air is exchanged. When a bulding is on fire and the cable starts to burn it gives off toxic fumes and will kill you. Plenum cabling is coated differently for burning purposes.
