Ultrasonic testing procedure

Ultrasonic testing procedure

Ultrasoniic testing has been used widely to determine rate of corrosion and erosion, or detecting discontinuities below the surface of a variety of materials. It's based on the same principal as sonar, a sound beam is transmitted into a material to determine thickness or soundness, and reflects back to the unit. This provides a thickness measurement with the accuracy of +/– .004" that can be trended for corrosion/erosion rate analysis.

Ultrasonic testing procedure

The system uses a beam of pulsed ultrasonic energy between 20 kHz to 50MHz in range. The transducer is made of a piezoelectric material which is able to convert mechanical energy into sound waves and then reverse that process, sending the pulse to the ultrasonic equipment. Whatever testing is to be done requires the use of reference standards for calibration and flaw characterization.

Nova Data Testing Services utilizes equipment able to "auto calibrate" to the material being inspected and can inspect high temperature equipment. This allows us to inspect a wide variety of materials, while in process, in various environments. Our equipment also allows for thickness measurements through coatings. This means no more damage to the coating in order to acquire an accurate result.

How to do search engine optimization

✓How to do search engine optimization:–

How to do search engine optimization

How to do search engine optimization

1. Describe your images with the use of the alt tag. This will help you for search engines that index images to find your pages and will also help readers who use text only web browsers.

2. Do not link to link-farms or other search engine unfriendly neighborhoods. A good rule of thumb is if your pages do not contain any words that reflect the content of the site you are linking to, do not link to it.

3. Use the same keywords as anchor text to link to the page from different pages on your site. This is especially useful if your site contains many pages. The more keywords that link to a specific page the better.

4. Make sure that the title tag contains text which a human can relate to. The text within the title tag is what shows up in a search result. Treat it like a headline.

5. Make sure that the text within the title tag is also within the body of the page. It is fully unwise to have keywords in the title tag which are not contained within the body of the page.

6. Submit to the search engines yourself. Do not use a submission service or submission software. Doing so could get your site penalized or even banned

7. Do not use the exact same title tag on every page on your website. All Search engine robots like Google might determine that all your pages are the same if all your title tags are the same. If this happens, your pages might not get indexed.

8. I always use the headline of my pages as the title tag to help the robots know exactly what my page is about. A good place to insert the headline is within the h1 tag. So the headline is the same as the title tag text.

9. Do not spam the description or keyword meta tag by stuffing meaningless keywords or even spend too much time on this tag. SEO pros all agree that these tags are not as important today as they once were. I just place my headline once within the keywords and description tags.

10. Insert keywords within the title tag so that search engine robots will know what your page is about. The title tag is located right at the top of your document within the head tags.

The law of leadership text

 If youru bussiness model is all ready exist and you faced larger, better-financed competitors then your violated the first law of marketing
           It states that if you are not in first in market then create a new market for your business. at first in car market has only car for ride then it splitting in different market to grow a new market like sports car for sports car market, luxury car for luxury car market etc. Always try to first in market.  The leading brand in any category is almost always the first brand into the prospect's mind. like Uber  in online texi service. IBM in computers.  Coca-Cola in cola.
       Not every first is going to become successful, timing is an issue, wrong bussiness model and execution . For example— Frosty paws, the first ice cream for dogs, is unlikely to make it.  The dogs love it, but the owners are the ones who buy the groceries, and they think that dogs don't need an ice cream of their own. They should be happy just to lick the plates.
                         So always create a new market category where you are one to do business.
It is the summary of "THE LAW OF LEADERSHIP" of the book"THE 22 IMMUTABLE LAW OF MARKETING".
This Post to help people who does not have time to read book and does not have hard copies. I'm not promote any kind of book it a summary to helping people to understand easily.

Moulding process in steel foundry (SAIL)

1. Moulding of metal in steel foundry in SAIL steel plant [kulti] [steel making]:-


It is an important process which is used for metal casting and shape or design the metal
Sharing my knowledge that i know when practice in sail steel foundry.
Take two boxes one is upper box and lower box then fit a pattern inside the lower box. Pattern  depends upon the requirement. After fitting pattern fill with silica sand in the holo part of lower box. Than make small holes and apply carbon dioxide thereby the silica sand will make hard and increase it's hardness. Then polished the surface and build the mould edge. Now the Time of casting sand will be attached with molten metal and separate top and lower part for used graphite power.
After making lower part, make top part of the part set on the lower part and riser and runner is set inside the top part then full fill the top part with silica sand and applying carbon dioxide for increase it's hardness and strength then separate from each other part and remove pattern which has been inside the mould.
Then join two parts again with moving crane for pouring moten metal or steel.

✓it note is in basics of works of 'SAIL: Steel Authority of India Limited' in kulti.

✓Hot-metal quality suitable for all steel applications

✓In there integrated electrical power generation is  possible.

✓Highest operational flexibility with respect to production capacity.

 2. Limitations:- 

✓It has the limitation in distributirg the coal and DRI in the optimised manner in the melter-gasifier.

✓Lost of chemical energy due to export corex gas.

✓ The system is maintenance onenied.

✓ It is provided with very sophisticated gas deaning facilities.

✓Hot DRI transfer and hol qas recycling are hazardous especially during there maintenance priod.
