On the cathodic protection of pipeline coating

When choosing a coating system for a given pipeline project, the most important feature of the design is the stability of the coating. What is needed for this is that the coating compound has a high resistance value after the pipe is installed and after stable backfilling, and the resistance loss is small over time. This is especially true when cathodic protection is used as an auxiliary method for coating protection.

When an unstable coating is used, a cathodic protection system that is fully applicable in the early stages of the pipeline may not provide complete protection when the coating breaks down (represented by a decrease in the effective resistance of the coating). The system requires additional current, which means additional cathodic protection and continuous additional expenditure. The overall economics of coating plus cathodic protection can be affected by poor coating.

Through the practice summary, the following conclusions can be obtained:

1) The choice of the best coating and proper use are the most important.

2) Cathodic protection must be supplemented with a coating to ensure 100% protection.

3) "Field" testing is more reliable than laboratory testing.

4) The results of the adhesion test have nothing to do with the cathode peel test.

5) Cathode peel test is the best test method to measure the protective effect of coating.

6) The current required for cathodic protection is the best way to test the protective effect of the coating.

7) Appropriate coating thickness is very important. Soil stress is one of the main problems.

8) Cathode stripping resistance and soil stress resistance are very important requirements for pipeline coating. If the pipeline coating is effective, these criteria should be met: adhesion, sufficient thickness, low moisture absorption / moisture transmission, chemical resistance (especially from alkali protected by cathodic protection) and flexibility.

9) The most appropriate system selection is important, but correct construction is more important.

1,Body wipes are Convenient
Convenience is without a doubt the primary reason why body wipes have become so popular. Since their introduction in the early 1960s, hundreds of body wipe products for a wide range of diverse uses have become available. You can find them at your local grocery store, drug store, and online. Fast-paced lifestyles resulting from the contemporary demands of home, job, family, and recreational pursuits keep us busy all day long. We all love Body Wet Wipes because they save us time.

Carrying the equivalent of a quick shower in your pocket or purse is a big deal for men and women on the go. No matter the situation, the ability to pull out a wipe and freshen up is one of the benefits of the modern age. Here`s a partial list of the different kinds of cleansing body wipes that are readily available.

2. Body Wipes Are Easy to Use
Going hand-in-hand with the convenience of using body wipes is their ease of use. No instructions are needed. Simply remove a body wipe from its individual wrapper or box and use it. Then, the used wipe goes in the trash or is flushed away. No rinsing, washing, or reusing the wipe is necessary.

For the most part, the disposal of body wipes has minimal environmental impact. Some flushable wipes can wreak havoc on community sewer systems–especially body wipes that are not made of cellulose fibers. Wipes made from materials other than cellulose (paper) biodegrade too slowly and can clog sewer system pumps.

3. Body Wipes Can Be Antibacterial
You don`t have to suffer from germaphobia (fear of germs) to use antibacterial body wipes. Touching surfaces in public places that have been touched by hordes of other people is a great way to catch something. Wipes provide us with a quick way to protect ourselves.

It`s not just shopping cart handles. It`s doorknobs, restaurant table-tops, handrails, and the weight machines at your gym. And–horror of horrors–children, too. In fact, children can be the grimiest and most germ-laden carriers of all.

Many researchers now say that washing hands frequently with regular soap is just as effective as using an antibacterial wipe or antibacterial soap. But if soap and water are not available, an antibacterial body wipe may be just the thing you need in a pinch.

4. Body Wipes Are Great for a Quick Freshen-Up
Ever feel like you need to freshen-up after lunchtime run? Or when you`re on the road or between connecting flights? Perhaps you have a social event planned right after work. Anytime you need to freshen up but are short on time, personal body wipes can help you feel ready and rejuvenated.

A body cleansing wipe can clear away perspiration, dirt, and unpleasant odor, helping you feel refreshed and revitalized.

5. Wipes for When You Can`t Shower
You may be among those who can`t bear the thought of not taking a shower every day. But what about those times when showering is impossible? There will always be those times when taking a shower isn`t an option. It could be a camping trip, a long flight, an unexpected travel delay, or even an emergency situation. When it happens, having a supply of shower wipes or bath wipes can certainly brighten your day.

[Body shower" wipes have recently become quite popular among consumers. Some full-body shower wipes can even temporarily replace taking a shower. These wipes contain a mild cleaning solution, vitamin E, aloe vera, and they`re alcohol-free. They`re larger and thicker than typical body wipes, too–about the size of a standard washcloth but several times thicker.

Shower body wipes can remove sweat, body odor, and dirt. They also moisturize, dry quickly and leave no sticky residue. They`re safe for cleaning all areas of your body. Some have a medicinal smell that disappears quickly as the skin dries. Full body shower wipes are helpful for those who may be bedridden and unable to bathe.

6. Body Wipes for Hygienic Cleaning
Cleaning up [down there" has a long history– as long as humans have been roaming around planet earth. Before the advent of toilet paper, invented in the 19 century, we homo sapiens used dried leaves, clay, newspapers, and even Sears catalogs. Now, we have body cleansing wipes for use in the bathroom. What started out as a welcomed and convenient way to wipe baby bottoms has now grown into a billion-dollar business for adults, too.

However, there are differences of opinion among physicians as to the medical benefits of using body wipes as toilet paper. Some medical professionals say there`s no additional benefit compared to normal wiping with toilet paper, while others note that a sanitary wipe is more thorough. Most people would agree that using bathroom wipes just feels better.

Most leading brands of hygienic bathroom wipes are alcohol and paraben-free. They contain mild cleaning solutions and may contain aloe and vitamin E. Typically, these wipes are also fragrance-free. Because flushed wipes were known to clogging sewer systems, many wipes today are made with cellulose or plant-based fibers which biodegrade quickly.

7. Wipes for Exfoliating
Exfoliating wipes are different from facial Cleaning Wipes . While both are designed to clean the skin, exfoliating wipes are designed to remove dead skin cells, oil, dirt, and germs. The definition of exfoliate is [wash or rub with a granular substance to remove dead cells from the surface." A good exfoliating wipe will unclog skin pores and allow your facial skin to breathe.

What exactly makes an exfoliating wipe different? The ingredients. Because exfoliating wipes are made to scrub and exfoliate, their texture will be rougher. Microbeads are the most common additive that gives exfoliating wipes the ability to remove dead skin without harming the living skin. Other ingredients may include oils, vitamins, glycerin, crushed oats, or wax beads.

8. Wipes for Women
Ladies, it`s easy to become dependent on body wipes for the face. It`s a great way to remove makeup. With hundreds of brands available in the makeup aisle or online, there`s something to meet the needs and wants of anyone wearing makeup. Yes, they`re easy to use, but here are some things you may not know about face wipes.

Do makeup wipes clean effectively? While quick and convenient, some dermatologists say that face wipes may not be the best way to remove makeup at the end of a long day. Instead of cleansing and removing makeup, wipes may just be pushing the dirt and makeup around your visage. They may be even lead to clogged pores. But when soap and water aren`t available or you have time constraints, makeup wipes will certainly do.

Wipes are different–so choose wisely. When shopping for Facial Wipes , remember there are differences. Some wipes are meant for removing eye makeup, while others are designed for deep cleaning. It`s important to carefully read the labels.

Great for the beach. Facial Cleansing Wipes are great for a day in the sun and sand. You can use them to remove old sunscreen and to refresh your skin.

Great for facial cleansing on the go. After a long plane, car or train ride, a facial cleansing wipe can help you feel reinvigorated. And, you won`t rile the TSA with a package of face wipes.

Effective for removing stains. Facial body wipes can even remove small stains from your clothing. Gently pat a face wipe on a newly acquired stain and the stain will likely disappear. Don`t wait. If the stain has been there too long, all the rubbing in the world with your face wipe won`t do any good.

Facial wipes are not a substitute for washing. While using a face wipe to remove makeup is quick and convenient, don`t get out of the habit of washing your face. A thorough and complete cleansing of the face still requires good ol` soap (mild) and water.

Get rid of deodorant stains. Don`t you hate it when you`re applying deodorant and accidentally get some on your dark shirt or dress? When that happens, grab a face wipe and gently wipe the stain away. This should take care of any unwanted deodorant residue.

Clean up when dying hair. If you`re one who likes coloring your own hair, you know that when finished, there`s always dye on your forehead and neck. A face wipe will quickly and gently remove dye from your skin.

9. Wipes for Men
What wipes are formulated especially for men? Wipes for men contain fragrances and ingredients more suited to the masculine side. These face wipes are infused with an orange fragrance or other masculine-oriented colognes. They`re not made for removing makeup but will hydrate, refresh and soothe a man`s face.
