Sometime it is impossible to manage your skin specially , when you wake up and find a huge spot on your nose or on a face. However, there are ways to prevent and treat common skin problems. It is a common inflammatory skin disease characterized by pimples on the face, chest, and back. A pimple starts when the pores in the skin are blocked with a type of oil called sebum, which normally lubricates the skin and hair. It is common during teen age , when hormones are flexible, causing the skin to overproduce sebum. Because many oil producing glands are on the forehead, nose, and chin, this area the T-zone is where a person is most prone to pimples. Harsh scrubbing and over-washing should be avoided due to the fact that they can increase skin irritation and an over-production of oil in compensation for the heavy cleansing method. This could clog pores. Also , products which are gentle exfoliants are helpful and healthy skin cleansers. Those with scratchy ingredients such as fruit seeds or shells should be avoided as they can damage the skin. Alcohol is a bad ingredient for facial products and can remove the top layer of the skin, and cause an over-production of oil. You should avoid touching, squeezing, and scratching an acne affected area. Because the blemishes have been forming for weeks, the infection could potentially spread inward causing skin damage , scarring and increased infection. So, a dermatologist is a perfect person to be shown the damaged skin, if the blemishes are recurring at a commonplace. A dietary supplement, also known as food supplement or nutritional supplement, is a preparation intended to provide nutrients , such as vitamins, minerals, fatty acids or amino acids that are missing or are not consumed in sufficient quantity in a person's diet.

Nowadays, due to our busy schedule of life , we tend to miss out on the essential nutrients such as protein, vitamins and minerals which are responsible for our good health. Good nutrition is the most important factor in achieving optimal health. If we face some type of challenges in life which doesn't allow us to have a balanced diet all the time, then supplementing out daily diet with food supplements is quick, easy and effective way to fill nutrient gaps. Supplements are substitute of the essential nutrients, which we do not eat , in our busy daily routine. Since these Supplements provide us with the required nutrients, it helps us to get extra energy and helps us build muscles. A person who is not having a balanced diet needs supplements. Importance of balanced diet has been mentioned time to time and to fill in the nutrient gaps, we do need supplements. Normal diet does not provide you with extra amount of nutrients.

But, good supplements give you an extra edge when it comes to Building Muscles. Collect different types of herbal information as well as know about herbal tea pregnancy. What is meant by Shell and Tube?

In Heat Exchanger,there is one most familiar type of exchanger is Shell and Tube Exchanger ,the designers are allow to use wide range of pressures and temperatures because of flexibility and compact.
Shell and tube heat exchangers are basically used for the transfer of heat in industrial process applications. They are available in a variety of diameters and lengths.It is manufactured using the most advanced technology available and is specifically engineered for a wide range of applications. Every unit is designed, manufactured and tested to meet the quality requirements of the ASME code: Section VIII Division #1 and ISO 9002. There are two more categories

1. Petrochemical industry which tend to be covered by standards from TEMA
2. Power industry such as feedwater heaters and power plant condensers

There are number of common features specified regarding type of industry exchanger.A shell and tube exchanger consists of a number of tubes mounted inside a cylindrical shell. There are two fluid exchange the heat one fluid flows over the outside of the tubes while the second fluid flows arrangement through the tubes. The fluids can be single or two phase and can flow in a parallel or a crosscounter flow arrangement

Which Industries are used this Shell and Tube Heat Exchanger

The Heat Exchanger using industries are as follows:
1.Waste water treatment
2.Refrigeration systems
3.Wine-brewery industry
4.Petroleum industry.
5.Marine Engineering.

Advantage and Disadvantage of Shell and Tube Heat Exchanger


1. The Design of Shell and Tube Heat Exchangers is very Compact.
2. Its capable to handling with High Pressure.
3. Its less expensive too.
4. Can be used in systems with higher operating temperatures and pressures
5. Pressure drop across a tube cooler is less
6. Tubular coolers in refrigeration system can act as receiver also.
7. Using sacrificial anodes protects the whole cooling system against corrosion
8. Due to the pressure differential ube coolers may be preferred for lubricating oil cooling.


1. It is very tough to readily analyze the shell side of the tubes for scaling or tube damage
2. Less efficiency in Heat Exch. Cheap Jerseys From China Cheap Jerseys From China Cheap Authentic Jerseys Cheap Jerseys Wholesale Cheap Jerseys China Free Shipping Cheap NFL Jerseys Online Cheap NFL Jerseys Free Shipping Wholesale Jerseys Wholesale MLB Jerseys Wholesale NBA Jerseys
